Bug Description
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:
