[Bug 1577559] [NEW] USB Keyboard Barcode scanner drops chars


You have been subscribed to a public bug:

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

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

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.

This has been recreated on both a physical machine and VM.
