USB Keyboard Barcode scanner drops chars
Status in linux package in Ubuntu:
I'm using a USB barcode reader that mimics a keyboard. Using Windows,
the barcode reads correctly but in both Lubuntu 14.04 and Ubuntu
14.04, it drops some repeating chars. It consistently outputs the same
value in both.
503466052825 (Drops third 0)
8714976320 (Drops 7,8,6)
Using usbmon, I captured the input and translated the codes in
http://www.usb.org/developers/hidpage/Hut1_12v2.pdf . The values being
received from the reader are correct. The repeating chars are being
received by Ubuntu but are not output.
Looking at the output from lsusb, the device is recognised as a USB
HID but uses ID 0416:c141 which is described as "Winbond Electronics
Corp." which may not be the correct manufacturer.
This has been recreated on both a physical machine and VM.
