In 2.5.4[56] USB has the following problems:
- Kernel and lsusb unable to get strings (empty in driverfs and lsusb
gets EPIPE from usbdevfs)
- bAlternateSetting == 0 on interface 1 of my SpeedTouch USB (this
prevents loading the firmware to it)

Reverting all the USB changes in 2.5.45 fixes the problems.

Here is what happens with broken kernels:
