  I apologize is if this the wrong place or format for the report.  This
  is my first bug report.
  
  An HID bluetooth barcode reader scanning Code128 barcodes (and possibly
  other symbologies) will drop repeating digits if they are less than 8
  digits apart.  This does NOT happen if the repeating digits are back to
  back.
  
  
  Example the number encoded in a code128 barcode then scanned with a bluetooth HID barcode reader:
  
  -"1234567890" will properly return "1234567890"
  -"10"  will properly return "10"
  -"100" will properly return 100  (the repeating zero's are back to back, so no problem)
  -"1010" will IMPROPERLY return "10"
  -"10101" will IMPROPERLY return "10"
  -"101010" will IMPROPERLY return "10"
  -"1010101" will IMPROPERLY return "10"
  -"10101010" will IMPROPERLY return "100" (yes 100)
  
  The test system has a USB (Anycom or Trendnet) bluetooth USB dongles
  with an Intermec sf51 bluetooth HID barcode scanner successfully paired
  (as HID profile) to the Ubuntu system.
  
  Using USBMON in debug I can see the all of the proper digits coming
  across in hex.  There are no dropped digits.  I then used HCIDump and
  again saw all the digits coming across without loss.  Using Showkey
  shows the problem I believe.
  
  Scanning the barcode "1010" shows this in showkey:
  
  keycode 2 press
  keycode 11 press
  keycode 2 release
  keycode 11 release
  
  Keycode 2 is "1" and Keycode 11 is "0".
  
  More complex numbers better illustrate the problem:
  
  Scanning the barcode "L003184192" returns "L00318492".  The "1" is
  missing.    This is what appears in showkey (I've added the ASCII letter
  after the "press" or "release" statement from showkey for this example
  text):
  
  keycode  42 press (shift)
  keycode  38 press  (L)
  keycode  42 release (shift)
  keycode  38 release (L)
  keycode  11 press (0)
  keycode  11 release (0) 
  keycode  11 press (0)
  keycode   4 press  (3)
  keycode   2 press  (1)
  keycode   9 press (8)
  keycode   5 press (4)
  keycode  10 press (10)
  keycode  11 release (0)
  keycode   4 release (3)
  keycode   2 release (1)
  keycode   9 release  (8)
  keycode   5 release (4)
  keycode  10 release  (9)
  keycode   3 press (2)
  keycode   3 release (2)
  
  What looks to be happening is that the missing "1" key is "pressed" at
  the beginning of the input and is not "released" in time to be "pressed"
  again.
