Unitech AS10-U keyboard like Barcode scanner - Raspberry Pi Forums
hi
have barcode scanner above. supposedly works keyboard. works magic in windows without having install drivers. trying work pi, having hard time.
vendor id 040b , product id 6543. pi can see after plug in @ /dev/usb/hiddev0, works wheni access /dev/input
od -x </dev/input/by-id/usb-040b-longnumber
command above displays lot of hex numbers don't seem consistent every time scan same bar code.
cat </dev/input/by-id/usb-040b-...
displays tons of ascii characters. not sure how extract actual bar code.
import sys
fp = open('/dev/input/by-id/usb-040b-longnumber', 'rb')
tstr = ''
while true:
buffer = fp.read(8)
c in buffer:
if ord(c) > 0:
tstr = tstr + c
print tstr + "\n"
these simple codes i've tried. guidance appreciated.
thanks
