If I plug a USB device into the machine it does not give me the balloon pop up that tells me that it can work faster. So I surpose it has USB 2.0.

But can I check it out someway?

You don't mention what T40 you have, but I guess it is a 2373-14G (based on your first post in the thread T40 have problem with screen that falls out), so I looked up the equilavent US-model of this (being the 2373-14U) which I found the detailed specs for in the tawbook (official title being: "Personal Systems Reference, IBM ThinkPad Notebooks A, T, X, and G Series, 2000 to 2005 - withdrawn, May 2005 - Version 291"); see page 47 there saying:

Ports:

Two USB (Version 2.0) / parallel / external DB-15 monitor / infrared (4Mbps) / RJ-11 (modem) / RJ-45 (ethernet) / no keyboard or mouse or serial ports (use USB)

PS: I suggest you consider updating your "footer" (currently saying: "I'm danish. Sorry for my sometimes bad english spelling and understanding") to be reflect things the way I beleive they are: I'm Danish! I read and understand English perfectly!

This is a known issue on T4x machines, and amounts to a minor system board failure, when the USB ports revert to 1.1 or quit working altogether. Nothing short of motherboard replacement cures it.

My advice would be to get a PCMCIA USB 2.0 card and feed your needs from there.

Good luck.

I don't think i got that???

Do you mean that the USB sometimes act as a 1.1?

I have no problem when using my USB stick.

But when i boot up on a ghost.exe to make a ghost to my USB harddiks, it takes hours...... SShhhhhh...

And my ghost get in error after some time....

Not every device that you plug in will trigger the "can work faster warning"...

i don't get "can work faster warning"... at all.

if i Move a file from my thinkpad to my USB harddisk, how fast does it than have to be moved if it's USB 2.0?

this way I could see if it's USB 2.0 speed?

or maybe ghost can't use 2.0 speed in DOS mode?

If your file transfer speeds are 1.5MB/s or lower, you're running at USB 1. If your file transfer speeds are 10MB/s or higher, you have USB 2 (assuming the hardware at the other end of the cable is USB2, eg a portable HDD). Note these are real MB/s not Mb/s!

Hello,

I suggest you to use HDTach, to bench your USB devices.

You'll find it here :

You do know that Ghost has a performance control - right. Default is very slow.

Does my T40 have USB 2.0 ?
