Hi, I lost /dev/bus/usb during remote system upgrade (Ubuntu 9.04 -> 9.10) on Watcher telescope control computer (@Boyden observatory, South Africa). I do not see /dev/bus/usb, and lsusb does not show anything. It worked before, USB devices are present in dmesg, so I think USB subsystem is working properly. To debug this it will help me to know how udev creates and populates /dev/bus/usb - which rule(s) does this, how to debug what might be wrong. We hit some problems during system upgrade, and I am pretty sure this is related to them. I just need to debug the machine, which is while I am in Europe and machine is in South Africa a bit difficult (and dangerous to change anything, as it might not boot and then I have a problem again..). Thanks a lot for any hint.
