USB Keyboard Barcode scanner drops chars

Asked by Rory O'Siochain on 2016-05-02

I'm using a USB barcode reader that mimics a keyboard. Using Windows, the barcode reads correctly but in both Lubuntu and Ubuntu, it drops some repeating chars. It consistently outputs the same value in both.

For example:
Barcode
5034660520825 becomes:
503466052825 (Drops third 0)

Barcode
8714789763620 becomes:
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.
