Thinkpads Forum

My T23 has two USB ports. Am I right in thinking these are USB 1.1 standard and not USB 2.0? How does one tell?

On my t42 if I go to device manager and open USB controllers it lists them as enhanced 2.0 or something like that. On my t30 it leaves out the enhanced and 2.0. I think it will designate the 2.0, not the lesser.

The t23 usb ports are 1.1 not 2. Kyocera is correct about the device manager "enhanced" designation if usb 2 drivers are installed (which should only happen if usb 2 ports are available).

You can get usb 2 speed on a t23 with a PC card USB 2.0 adapter.

Thanks dsvochak for definitive answer. Have checked for enhanced driver on the T23 - nothing doing as advised. Also checked same on my desktop PC which I thought had USB 2.0 and found nothing there either so must assume that is also USB 1.1 after all.

-- are USB 1.1 standard and not USB 2.0?

As you probably know, there are PC Cards (aka PCMCIA) that provide USB 2.0 ports for machines that only have USB 1.1 built in.

I've been using a (now old) Keyspan USB 2.0 Card very happily.

IMO this makes machines like the T30 a great deal now. The machine is otherwise fairly uptodate (Pentium IV and 802.11), and the problem that they lack USB 2.0 can be gotten around.

All bought refurbished
T42
T30
X23 (upgrade to 60GB HD also helps with speed)

IMHO, PCMCIA cards that combine USB 2.0 **and** FireWire are even more versatile. Cheap too.

--First I heard of a combo USB\firewire PC card. Any advice about where to look for one for a sensible price?

I have a Lacie USB 2.0/FW 400 PCMCIA card that I purchased from Cendirect in Canada. Orange Micro makes one as well.

Does anyone know if the PC Card USB 2 adapter actually gives us true USB
I/O speed?

I put one in a 600E ThinkPad, and the speed boost was quite noticeable to an external USB 2.0 DVD writer. I didn't actually measure the thoroughput though.

Thanks for the reply Gomjabbar. I purchased a serial port to USB 1 adapter two years ago thinking I would get an I/O speed boost. I couldn't notice any speed different, though Radio Shack (The maker & seller) claimed I would get near USB 1 speed.

I couldn't see how I would since, the adapter box shouldn't be able to increase the serial port speed. I wanted it mostly to improve a PC to Handheld connection anyway, so I kept the device.

A PCMCIA USB 2.0 card for PC -> handheld is probably ok.

Keep in mind that the PCMCIA USB ports are not "powered".

Some USB pcmcia cards come with a power supply - it plugs into the
card itself.

(I ran into this a while ago with a USB camera.)
