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: Stopping hotplug subsystem: pci pci [success] usb usb [success] isapnp isapnp [success] ide ide [success] input input [success] scsi scsi [success] done. Starting hotplug subsystem: pci pci [success] usb usb [success] isapnp isapnp [success] ide ide [success] input input [failed] scsi scsi [success] ide ide [success] input input [failed] scsi scsi [success] done. dmesg | grep usb shows me this: usb.c: registered new driver usbdevfs usb.c: registered new driver hub ehci_hcd 00:10.3: VIA Technologies, Inc.
