Gente
Este mail me llego preguntando como areglar una problema con USB.
Yo propociono hacer un nodo /dev/input/mice pero parece que esto no
funciono.
Alguien tiene alguna idea?

2 . lspci was not supported.
3. lsmod
no modules..
4. cat /proc/bus/usb/devices
none..
5 . cat /proc/bus/usb/drivers
hub
usbdevfs
hid
i tried to insert the modules uhci.o and usb-uhci.o
after booting, but it is saying
init_module : No such device
After that when i try to see the lsmod or /proc/modules nothing was
shown..
But when i insmod again the same usb-uhci.o now it gave some output and
then segmentation fault and then in /proc/modules it gave
usb-uhci 22928(initializing)
in lsmod it gave uninitialised
cat /proc/usb gave the following info..
SA1100 USB Controller : Not Configured

I dont know what's happening......
By doing mknod for /dev/input/mice and cat /dev/input/mice is just
keeping
quite even if i move the mouse..
** Same is the case even with usb-uhci compiled into kernel....
I think this gives more details of the situation.......
Waiting for your answer sir...I need badly soon do the work
urs sincerely
