I have just started getting a message that a USB device is not working properly. This is on a new Thinkpad T60 running Windows XP Professional SP3.

I have had all devices attached for about 10 days or so.

When I go to device manager there is no sign of a problem: everything is working correctly.

I am unable to find out which device it is.

I searched this forum but the only reference I found was to older computers which may not be Usb2 capable. This is not my problem.

Any ideas?

Thanks.

EDIT: I realized I had a harddrive attached but turned off. Although I could not track down any error messages except the balloon that came up, I have disconnected it and, so far, no messages. We'll see over the next day or two, but this may be the problem.

Thanks

EDIT: This has not solved the problem. I get the message that one of the USB devices has malfunctioned and it points to "USB root hub (2 ports)" and shows an unused port and an unknown device. However, when I check my device manager, it says that there are no problems, everything is working as it should. ??

EDIT: I now found the event log view and there are 2 types of error messages. They do not relate to the time that I get the balloon. 2 of the 3 are "Ati2mtag" errors and the third is "System Control Manager". Are these related to my problem, and the balloon just pops up randomly?

EDIT: well, I'm still having the problem, and have narrowed it down to a malfunctioning device. Thanks to all.
