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:

_All_ the changes? Hm, that was a lot :(
Anyway, which USB drivers are you using? That might help us narrow this
down a bit.
thanks,

speedtouch 8932 3
hid 39652 0 (unused)
uhci-hcd 27900 0 (unused)
usbcore 88372 2 [speedtouch hid uhci-hcd]
Anyway the problems are obviously either in the USB core or in the uhci
driver.

Oops, I don't think I fixed up that driver based on the other changes
that happened in the USB core. I'll try to find some time to look at
it, but can't guarantee anything...

Hm, no, I take that back, I did fix up the obvious compile time fixes
for that driver. I wonder what broke it...
What's the symptoms of it not working?

For what it's worth. On my system I have problems with 2.5.4[56]. And they
seem to be related to USB. When I boot with nousb it boots OK. But without
this option I get OOPSes and panics everywhere. The system is happy with
2.5.44.
Some of these OOPSes happen during shutdown in device_shutdown. But panics
during boot are happening too. And then all I see on my screen is that the
call-trace in is reap_timer_fnc somewhere.
I've tried switching on USB_DEBUG, but that didn't help much. Neither the
DEBUG=1 in drivers/base/power.c.
My machine has a MSI K7T266 Pro motherboard with Athlon 1.3GHz. It has a
VIA chipset, 82C686b+VT8233. Harddisk: IBM Deskstar 60GXP, 40Gb.
I'm using CONFIG_USB_UHCI_HCD_ALT=y
