Does this mean that a process wont go to sleep in the kernel
mode(2.4.x) unless it explicitly call schedule() or its variants?

Hi, all
In usb.c (kernel 2.4.20, I have to work on this kernel version),
function usb_start_wait_urb() sets the process state to
TASK_UNINTERRUPTIBLE and add the process to awd.wqh before calling
usb_submit_urb(). What is this for?
And What if scheduling happens during the usb_submit_urb() but b
to the bios area now. I'll let you know if I fix it:)
Thanks,
Dave

Usb portion of it with a linux 2.6.6 kernel. I can't see anything
In the /proc/bus/usb file listing, yet it is mounted. Can anyone

following messages:

usb 3-1: device not accepting address 2, error -110

I stumbled into a couple of questions for which some on this list might know
the answer rightaway, and, if possible, i like to learn about your advice or
opinion.
