Comment 44 for bug 88746

I have an old mainboard with a card reader attached to one USB port. Since when I upgraded to Feisty, I have not been able
to read two of my USB sticks, which I could read before Feisty and which I can read on a different PC with Feisty. However,
the card reader works and moreover I can read an MP3 reader with a USB interface. The "modprobe -r ehci_hcd" trick works
for me. If, after trying unsuccessfully to read a USB stick, I launch usbview, it hangs and the kernel logs show repeatedly
this:
May 6 21:33:12 localhost kernel: [ 648.336000] sde : READ CAPACITY failed.

Kernel is 2.6.20-15-lowlatency, mainboard is an anonymous PM-999BA-AVS, chip VIA KM133+686B, AGP 4x,
integrated Savage4 (disabled), FSB 266 MHz, ATA 100, AMD Duron 1000 MHz, Radeon 9250 128 MB, USB audio
Creative.

In the attached kern log, I attach the USB stick at May 6 21:45:10, which fails. I then remove the ehci_hcd module and
try again at May 6 21:51:45, when it works.
