Description of problem:
On thinkpad t61 there are three usb ports. One is on the left side of the computer and the other two are on the right. The one on the left works great. The two on the right do not work. I have noticed this with multiple devices such as usb flash drives, external hard drives, and a wireless usb mouse.
I originally searched the Fedora forums and found a post of someone else with the same problem. I the post was old with no responses so I replied to get it noticed. After a few more posts I was instructed to run "dmesg > ~/dmesg.txt" and then post the resulting text file. I did so and the other forum member pointed out a few lines of the text file that were to blame. He then instructed me to report the bug.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Attach usb device to one of the usb ports in question.
If I'm attaching a drive, I would expect it to mount. If I'm attaching a mouse then I would expect the mouse to be recognized and work.
irq 19: nobody cared (try booting with the "irqpoll" option)

1. T61 is different from X61 in this regard
2. It's both kernel problem and a BIOS bug, F8 has what is required
to work if BIOS is fixed too.
you are using ThinkPad BIOS version 1.14
If you upgrade to the latest BIOS your problem will be fixed.
