[sane-devel] microtek scanmaker 4900

[m. allan noah]

i dont think that sane-find-scanner or check-usb-chip use the backend
files. they are independent programs.

it seems that the problem is this scanner uses USB_CLASS_PTP? thats
mostly used by cameras, and its not even listed in usb.h on my older
machine, so if you want to add it, you'll have to use an ifndef in
sane-find-scanner.c

there is no check for the sm3840 in check-usb-chip.c

even if you get those two programs to work, you still have to add
support to the backend, and there is still no guarantee that it will
work.
