USB broken
Hi,
I am running Debian Sarge, kernel 2.4.25-1-386. USB had been working fine and
then one day it broke. I do not think I had made any changes to the system
between the day it was working and the next day when it was not.
dmesg indicated that hubs were found and drivers loaded, but if I connected my
palm pilot and pushed the hot sync button, nothing appeared in syslog and no
connection was made. Also xsane could no longer find the scanner and my usb
printer also did not work. I also could no longer mount my camera.
I tried /etc/init.d/hotplug restart and there was a message, "can't synthesize
root hub events". I also got "input failed". Googling "can't synthesize root
hub events" located a post that suggested either /proc/bus/usb/devices was
missing or usbutils was not installed. The proc file system was present, so
I tried installing usbutils. It installed fine.
Again I tried /etc/init.d/hotplug restart. "can't synthesize root hub events"
was gone, but "input failed" was still present. Here are the messages
from /etc/inti.d/hotplug restart:
