2.6.2 USB Problem
Apparently, the old usb-uhci module has been changed to uhci-hcd. uhci-usb
exists but it is for bluetooth. Alsa's snd-usb-audio, in any event, will only
work as before with uhci-hcd loaded.
This module is very problematic and will not shutdown correctly. From a
console, a modprobe -r on it will hang up and have side-effects. On shutdown,
one gets a couple of messages suchs as urb -128, usb-request-urb -32 and then
it hangs.
I have stopped it sometimes with control/alt/delete. The next stop or two of
shutdown proceeds but it will hang again. Momentarily!! hitting the power
switch will allow SOME cleanup and a shutdown (even if a reboot was being
executed). So a couple of questions:
1. How to fix the errant module/USB system. The new usbfs is mounted but this
changes nothing.
2, There is something now sitting on the power switch (unknown key
pressed--the keyboard is usually disabled at this point) that prevents an
immediate power off on a (suitably equipped/supplied MB--this is a good
capability if is is for real!). If it can be configured, it could assure
orderly dismounts and prevent file-system problems. Is it and how to
configure it?
