T40 - USB2.0 not working well

#1 Post by wtpark » Tue Jul 26, 2005 4:30 pm

Hello,

I own a T40 2374-4CU. My computer has usb2.0
however it doesn't recogize some of the usb2.0 peripherals sometimes
and I have no control over it.

Does anyone have similar experiences?
Anyone know how to fix this symptom?

Thanks

Try using a cable that specifically states it's USB2.0 rated.

Report back.

If your BIOS has a setting to disable USB, then reenable it in the BIOS. Next, check in device manager. Go to Start > Control Panel > System > Hardware > Device Manager. Do you see any devices marked with a red x or a yellow ! , if so, that may be your problem. Right click on the device and uninstall it. Reboot Windows. If you still have no USB showing up in device manager, I would guess you have a problem on your motherboard.

You can go to the device driver matrix page for your laptop and download PC Doctor to run diagnostics. You can get to the device driver matrix page for your T40/P by starting at the following link:
