I apologize, but I currently have no ubuntu later than 12.04 LTS for
several reasons. However, as far as I used the device, it seems to work
well current 12.04 LTS.

regards

Title:
  USB barcode scanner (emulating keyboard) crashes with current kernel

Status in The Linux Kernel:
  Fix Released
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I just experienced a problem that seems to be related to the kernel's
  HID driver.

  I have a USB barcode reader that I sometimes use to read the ISBN of
  books of my library. That barcode reader emulates a keyboard. If you
  scan a barcode, it just appears as if you had entered the encoded
  number on  a keyboard, so it does not require a special driver.

  I used that scanner last spring (not sure whether this was ubuntu
  08.04 or 08.10) for the last time, where it worked pretty well. Now I
  tried to use it again (checked with two ubuntu machines) but it does
  not work anymore. When plugging in, the LEDs are lit, but the beeper
  gives an unusual sound. When trying to scan, it scans once, but
  nothing appears on the console, and then the scanner is dead (until
  pulling it from USB to cut it from power supply).

  The scanner itself is ok, it still works under windows on the same
  machine, although it requires a reset to factory defaults after having
  it tried with Linux.

  I guess that the current kernel tries to perform some configuration or
  any other special things with USB keyboards, that is not compatible
  with the 'keyboard type' USB scanner.

  
  dmesg when plugging it in: 

  [34828.208582] usb 6-3: new low speed USB device using ohci_hcd and address 7
  [34828.374898] usb 6-3: configuration #1 chosen from 1 choice

  lsusb:

  Bus 006 Device 007: ID 1130:0001 Tenx Technology, Inc.

  Probably it is the bug described under
  https://lists.linux-foundation.org/pipermail/bugme-new/2009-May/021980.html
