Title:
  [PATCH] IR doesn`t work (lirc_igorplugusb)

Status in “lirc” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: lirc

  Hi, I have IgorPlug-USB(AVR) receiver, it works on Windows fine with
  4-5 transmitters I have tested.

  I have installed generic Jaunty (Intrepid, some other custom kernels.. with no luck too).
  I have Installed lirc package and chose from the list Igor Cesko USB receiver.

  On boot I see that appropriate kernel module loaded without errors:
  $ dmesg | grep lirc
  [   21.824130] lirc_dev: IR Remote Control driver registered, major 61 
  [   21.868206] lirc_igorplugusb: USB remote driver for LIRC v0.1
  [   21.868218] lirc_igorplugusb: Jan M. Hochstein <hochstein@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>
  [   21.944392] lirc_dev: lirc_register_plugin: sample_rate: 100
  [   21.993818] lirc_igorplugusb[3]: Ing. Igor Cesko, Copyright(c) 2003 IgorPlug-USB (AVR) on usb3:3
  [   21.997883] usbcore: registered new interface driver lirc_igorplugusb

  So I run irw utility to test the system and press buttons on transmitter, irw gives no output instead of received characters.
  $ irw

  In dmesg output I see buffer overrun error on each keypress:
  $ dmesg | grep lirc
  [   21.824130] lirc_dev: IR Remote Control driver registered, major 61 
  [   21.868206] lirc_igorplugusb: USB remote driver for LIRC v0.1
  [   21.868218] lirc_igorplugusb: Jan M. Hochstein <hochstein@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>
  [   21.944392] lirc_dev: lirc_register_plugin: sample_rate: 100
  [   21.993818] lirc_igorplugusb[3]: Ing. Igor Cesko, Copyright(c) 2003 IgorPlug-USB (AVR) on usb3:3
  [   21.997883] usbcore: registered new interface driver lirc_igorplugusb
  [  165.356078] lirc_igorplugusb[3]: Device buffer overrun.
  [  165.700094] lirc_igorplugusb[3]: Device buffer overrun.

  The same story with all transmitters I tested. All of them work in
  Windows. I think the problem is in lirc_igorplugusb kernel module,
  almost the same code in all distributions.

  I have now skills in IR technology so.. reported this bug to you. Any
  help will be appreciated.

  Thanks, Denis
