This is weird.
You should get the same response when running the scanimage -L command
twice. Perhaps the first time, hotplug had not updated the USB
permissions yet. What kernel are you running?

I don't know about the assertion. To me this looks like a bug
because scanimage -L should not have anything to do with tl_x
tl_y br_x and br_y (the scan area coordinates).

try /proc/bus/usb not /proc/bus/ubs
