USB USB Ports do not work in 2.0 mode
USB USB Ports do not work in 2.0 mode
My 2373-92U does not recognize any USB 2.0 devices and always pops the message " this device could run faster..." and continues in USB 1.0 mode
I tried to load the Intel Chipset drivers from the IBM support site: no improvement
With a second XP-SP2 installation on the same machine, I verified that the MB hardware is ok - here, it works in USB 2.0 mode.
Any idea how to fit my work image - I just don't want to re-install everything.

Possible Solution
You need to install the enhanced USB 2.0 driver - Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD
Check out this link to this same topic on this forum. The easiest way I know to install this driver is to update to Windows XP SP2 or Windows 2000 SP 6.

Could be a system board problem. The USB2 ports in some T40 models seem to fail sometimes. Do a search for USB2 problems here on the forum, I'm sure you'll find a couple threads.
Homebuilt PC: AMD Athlon XP (Barton) @ 1.47 GHz; nForce2 Ultra; 1GB RAM; 80GB HDD @ 7200RPM; ATI Radeon 9600; Integrated everything else!
I think you'll find a lot here. The bottom line of the story seems to be that if you put something on your USB connection that demands a little more current than the controller chip likes to give (which may still be within USB specs...), it fries. And the solution is a new system board.
I had this problem, and after a bunch of bumping through the service manual tree (did you? yes. did you? yes. did you? yes.) I told the guy on the phone that I'd read here that their solution was to replace the board. He put me on hold for two minutes, and came back to tell me they were going to replace the board. Now it works fine.

2nd round of thoughts....
I just realized that my post may not have made much sense as it was not complete ...
My thinking is that assuming that the hardware/motherboard are OK ( and you mentioned that you verified this through a 2nd WinXP SP2 install ) then it would seem that this is a software problem. The easiest way I know to solve software problems with hardware is driver installation which is where my argument comes from.
In a basic T4x install from Recovery CDs, you get Win XP which only comes with USB 1.1 drivers. To get USB 2.0 speeds, you need to install the enhanced drivers hence the need to install chipset drivers etc etc. I was arguing that the easiest way to bring your USB speed up to 2.0 is to install Win XP SP2 that will automatically do this for you. If you do not want to do this, I would look for the .inf file that contains the headers for "Intel(R) 82801DB/DBM USB 2.0 Enhanced Host Controller - 24CD" which is the missing driver and work from there.
(
This file is 'usbport.inf' that is/should be in the folder c:\windows\inf. Right click on the file and choose "Install" then follow the prompts. You need to have the correct driver files handy though but you can copy those easliy from the folders for your 2nd Win XP SP2 install or just point the installation process to those folders when prompted. According to my install, the files you need are
usbehci.sys that goes to c:\windows\system32\drivers
usbhub.sys that goes to c:\windows\system32\drivers
usbport.sys that goes to c:\windows\system32\drivers
hccoin.sys that goes to c:\windows\system32
usbdui.sys that goes to c:\windows\system32
and finally
usbport.inf that goes to c:\windows\inf

Re: 2nd round of thoughts....
I don't think this statement is necessarily correct, at least for machines recently acquired from the factory. For example, my recently purchased T42p came with XP-SP2 already installed as part of the factory preload, (even though the TAbook description for my model did not specifiy XP-SP2 as it does for some models). I assume that the recovery disks I created on this system would return the system to the same state that it was in when received from the factory, i.e., with SP2 already installed.smugiri wrote: In a basic T4x install from Recovery CDs, you get Win XP which only comes with USB 1.1 drivers.

My T42 came with Win XP SP1, august 2004, and it has the USB 2.0 Enhanced Host Controller - 24CD. So it's not just a matter of having SP2 or not. Apparently IBM installed this driver as soon as it became available, or it is also part of SP1. Just go into Access IBM and look at your system configuration, you will see several USB controllers, the enhanced 24CD version may be among them.

Hmmmmm...
The Thinkpad T40p that I have has an Intel USB controller, more specifically some variation of the "Intel 82801DB" USB controller ( I was not able to pull up more accurate information than this using dmesg ). It then seems to me that there is no way to get USB 2.0 on this machine with just Win XP SP1 since according to Microsoft, USB 2.0 in XP SP1 was ONLY supported for the NEC USB controller, an argument that is seems to have been supported by the fact that when I did a Windows re-install recently, I did not get USB 2.0 at the initial Win XP SP1 install. I would like to argue that that USB 2.0 support comes from some other source e.g IBM device drivers chipset drivers or from Win XP SP2 but not from a plain vanilla Win XP SP1 install on any hardware that does not have an NEC USB 2.0 controller.. It seems to me that this was the case with your T42. Another way to argue this is that since Centrino machines consist of an Intel chipset, processor and wireless card, they cannot have the NEC USB Controller and IBM does have T42 Centrino machines on the market. My argument then would be that it is impossible to have USB 2.0 from a plain vanilla Win XP SP1 install on a Centrino T42.
If you re-read my initial post, you will see that my argument was not that the only way to get USB 2.0 was an XP SP2 install, it was that one of the easiest ways to get USB 2.0 in cases where there is no hardware problem is to install Win XP SP2 . You could also probably do this with a chipset update etc etc. I was just suggesting that this is one approach that one could take that might work.

update...
According to this dmesg output from FreeBSD, it seems that Thinkpad T40p's have the 'Intel 82801DB (ICH4)" for a USB 2.0 controller.

USB ports think they're 1.1, not 2.0
Been researching this all week -- looks like a common problem: suddenly, for some reason, your T40's USB ports stop connecting at 2.0 speed, and only connect at 1.1, saying, "This device could run faster if you connected it to a USB 2.0 port."
Examples:
...at Lockergnome
...at Anandtech
...at DSLreports
This happens even on SP2, even after you update the BIOS, install the latest version of every driver, uninstall and redetect your USB drivers.
If you have SP1, this patch from Microsoft might help.
According to an IBM tech I spoke to today, if none of the above worked, the cure is to replace the system board.
Before I do that, anybody got a better idea?

Thinkpad T40 2373xxa
It seems like I read on this forum of others that had the same USB 2.0 problem with their T40's, and the solution was to replace the system board. Of course you would want to exhaust all other options first. But do a search on this forum for "USB 2.0" and "T40" to find what others have found. Use the Search button at the top of the page, and use the radio button: "Search for all terms".

Jessek,
It is probably faster to get the system board replaced. I called the 24/7 tech support line. Convince them it is the system board issue (already did the following, re-installing drivers, applying updates etc). Got a mail-in box from DHL the next day. I sent the laptop (T41) in using the provided box and got it back in 2 days. The USB ports work in Hi-speed mode now. Some posts here and on other boards suggested that plugging high current draw usb devices could have fried the hi-speed circuit. I don't but my laptop is fixed after system board replacement. Good luck.

Factory restore media
FYI
I got the factory restore media from IBM to one of my T42´s.
The media came from Scotland or Ireland, and was in my native language. (Danish)
It was with a SP2 added in the automatic install, whereas the original install included only SP1.

If people interested in this thread didn't search for other posts, I believe I remember from researching during my own experience that the reason the motherboard gets replaced is that one of the controller chips for USB is subject to some kind of burn-out if it's abused (one of the possibilities being from attaching a peripheral that requires too much juice), and that's what causes the reversion from 2.0 to 1.1. As a consequence of my experience, I'm now extremely careful what I attach, and make sure that if it needs extra power (my MP3 player *must* be hooked to the computer only when it's on its charger, for instance) I hook up the power before making the USB connection. Since my new motherboard, and being more careful, I haven't yet had any other problem. I'm also not going to try any of the various USB accessories that I really don't need (USB cubicle space heaters, etc. :-)

Correct me if I am wrong here but... A USB Coffee Maker would only require the power correct?
I mean, it isn't as if one actually needs a computer to charge or control them to make a cup of coffee. Then again, thinking about"designer" coffee, maybe it is worth a shot; perhaps a double too. Besides, it would go well for the extendable coffee cup holder that pops out from the right side of the machine, it seems the two should work perfectly together!

USB 2.0 working like USB 1.0
I had the same problem: USB 2.0 working like 1.0, tried everything: reinstall WIN XP, update bios, SP2, Windows update ...... and finally solution.
IBM T40 thinkpad has small but enoying POWER SUPPLY problems. Something is wrong in powering the system which influences the unstability of USB exits to function normally. What i did was buying USB 2.0 replicator (with 4 USB ports). The cheapest was "Sweex", but probably works with all other brands. So plug it in one of your 2 USB ports and wait system to regognize it. After that, plug one by one of your gadgets (USB DVD-RW, USB HD, USB mouse etc.) and all of them will work like USB 2.0.

I had this problem on my T40P ! USB didnt want go v.2.0 anymore. Replaced the board ... no works just fine!
I have anther USB problem though. After wake up from hibernation or Standby usb port is dead sometimes and i have to deaktivate/activate usb controller in HardwareManager. This strange thing i had with old and new board now ...

Re: USB port not working as 2.0 again
I doubt if the BIOS update is the problem, but here is the page with the BIOS updates on it. Look at the chart at the bottom of the page. It has links to the older BIOS versions.davekung wrote:Anyone know the file of the 3.17 BIOS. I want to try to restore to previous version of the BIOS to rule out BIOS issue.
Link: BIOS Update (Non-Diskette) - ThinkPad R50/p, R51 (1829, 1830, 1831, 1836), T40/p, T41/p, T42/p
Out of curiosity, what USB devices are you using with your T41?
DKB
Thanks for the link. I have external 2.5" HD enclosure, DVD burner enclosure and Sandisk Mobilemate (SD, Memory Stick/Transflash) reader. Tonight, I'm going to put the spare HD back to my T41 to see if USB 2.0 works. If it works (I hope it is the case), then it is Windoze problem, not BIOS. After that, I'll try to flash with the prior BIOS version to see it fix the problem.
New system board, all set now
Got my system board replaced this weekend -- USB ports now happily connect at 2.0 speed again. For once, I'm *really* glad I bought an extended warranty.

Hi
i have this same problem with my t40
now i give notebook to service
(i know, this cannot be softawe proble becouse usb 1.1 and 2.0 make 2 diffrent chips on board!)
now i'm user t43p,
The USB ports on my T40 2374 are suddenly running at dramatically slower speeds.
I've made two big changes recently:
1) The system board failed, and a Lenovo/IBM technician came to my house to replace it under the extended warranty.
2) I replaced the hard drive with a 100 GB model.
Other than the problem with the USB ports, everything is fine.
I'm assuming that one or both of those changes is the cause of the problem, but I don't know how to diagnose and repair it. If there's an easy fix, I'd rather take care of it myself than have Lenovo/IBM back out to deal with it.
Any suggestions? Thanks--
UPDATE: I updated the BIOS to 3.21, release date 2006-06-02, but it had no effect on the USB port speed.

Re: USB USB Ports do not work in 2.0 mode
My experience has been somewhat different, and may be useful, now that everything seems OK (+/-):
I've got a T40 that I've mostly replaced with a "new" used X60, so I decided to restore the T40 to fresh-install XP Pro status, maybe for my wife (though she's not sure yet). Long story shorter, many attempts failed totally, INCLUDING the 6 IBM Restore CDs I'd created on that same computer! Interestingly, here's what worked: Earlier, I had a devil of a time restoring Windows XP Pro to my X60. (The vendor had installed a bootleg copy of Windows 7, and hadn't made any IBM Restore CDs.) The only way that eventually worked on the X60 was to use the 6 IBM Restore CDs I'd created on the T40! Those are the SAME CDs that FAILED to restore the T40 properly!
But after I'd gotten the X60 going, and updated its drivers, I made two IBM Restore DVDs on it, with a used USB external (IBM) multi-drive I just bought. THOSE disks worked OK on the T40!! (One part that made me nervous was toward the end of the clean install, when it seemed to be running a version of CHKDSK, and truncated a bunch of first segments of INF files, so I was nervous that some drivers might be corrup.)
Everything seemed to work fine. Only problem was, I got nothing -- zero, nada, bopkes -- out of the USB drives! Device Manager showed the individual devices installed, but not the USB Root Hub. There were a few yellow exclamation points, but none seemed relevant. I researched, updated a bunch of drivers, and started worrying that the USB ports on the MoBo were fried. But rebooting with a Linux CD (from Macrium Reflect Free backup software) worked fine, and revealed my external HDD on a USB port, so the hardware was fine.
I saw nothing helpful in the BIOS.
I finally installed the new-ish Lenovo ThinkVantage Toolbox. It started nagging me to update the drivers for four "unidentified devices" that I'd been ignoring in the Device Manager. Lo and behold, when I clicked on "install (or update?) driver", each of them turned into a USB Root Hub!! (So THAT's where they went!)
After that, the USB ports SORT of worked, but not well. Basically, Plug and Play didn't work at all. So I could go into Disk Manager and assign a drive letter by hand, and then SOME devices would show up in Windows Explorer, but not all. (Thumb drives worked, but not my external HDD.)
To solve that problem, I opened Anvir Task Manager. I looked through the list of Services, and found several that involved PnP that were not set up to run at startup. I changed their status so they would. Now everything seems to recognize my external USB storage devices automatically
-- EXCEPT Windows Explorer, which still doesn't want to recognize my external HDD as "H:"!
But other file managers, like Q-Dir, show it just fine. I suspect that when I replace Windows Explorer with Explorer++, I'll forget all about this problem.
I hope this helps somebody else.

Re: USB USB Ports do not work in 2.0 mode
When I reinstalled my T42 I ran into the same problem. This is an odd solution but strangely enough it worked for me. They're USB 2.0 drivers for VIA chipsets even though the T42 doesn't use VIA to my knowledge.
