Please share the contents of that device's directory, so that the lookup
can be adjusted. I could only test with one single device, so I haven't
tried to be clever and think about all possible cases. Feel free to
spawn a specific hw-detect bug report for that.
See attached files with and without firmware. The following links and
directories exist only with firmware:
lrwxrwxrwx 1 root root 0 Mar 5 13:29 driver ->
../../../../../../bus/usb/drivers/p54usb
drwxr-xr-x 3 root root 0 Mar 5 13:29 ieee80211
drwxr-xr-x 6 root root 0 Mar 5 13:29 leds
drwxr-xr-x 3 root root 0 Mar 5 13:29 net
I am afraid that when the firmware is missing the driver is not attached
to the device so there is no direct way to retrieve it through /sys.
An indirect way may be to list loaded USB driver modules in
/sys/bus/usb/drivers or /proc/modules and search in their firmware
fields with modinfo ? Heavy and not 100% reliable though...# with firmware
# ls -l /sys/bus/usb/devices/2-4/
