[Bug 177166] USB UIRT: uirt2_raw: checksum error

[levander]

Public bug reported:

Binary package hint: linux-image

There was a regression in between 2.6.22 and 2.6.20 that made the USB
UIRT stop working.

The USB UIRT is an infrared transceiver.  You plug it into your
computer, and it receives signals from your remote control.  This is an
important device because it's not only the cheapest piece of hardware
that does this ($8), but it's also the only cheap one that connects via
USB and not via your serial port.  So, it's a very important piece of
hardware for HTPC software like MythTV.

Here is the error messages reported in /var/log/messages:

People are working around this issue by copying ftdi_sio.c and
ftdi_sio.h from a 2.6.20 kernel source code tree into the 2.6.22
sources:

It's definitely an upstread issue.  Here, they're talking about the
issue on the mythtv-users mailing list and distributions other than
Ubuntu:
