Comment 507 for bug 88746

I experienced this bug as well. I tried all the fixes in this thread as well as other sites but nothing worked. Sometimes my usb would die and lose all power and a restart wouldn't even bring back power. I could unplug and replug in my flash drive and it would be assigned a new address or I would have to totally shut down and reboot to reset my usb system. That made me think that the kernel was making my usb system crash at the bios level. I disabled my usb 2.0 in bios and it worked but I had usb 1 transfer speeds. So I disabled bios legacy support and re-enabled bios 2.0 on chip contoller. It again caused my usb to crash on large files and caused a slow down in transfers on small files. I read about plug and play crashing the usb on another thread (http://marc.info/?l=linux-usb-devel&m=106789579416232&w=2) and looked in my plug and play configurations in my bios. There was a option to assign irq to usb that was enabled. I disabled it and now have had no problems with transferring files. I think some people with this problem might be helped by this fix.

I have award bios (not sure the version) and am running ubuntu 8.04.1 fully patched
