Try to load the driver with
modprobe em28xx i2c_scan=1 and submit the output..
I have a few tools floating around which can be used to determine the
best keymap for your remote of your device.
The problem is pinnacle used to sell the same device in different
countries with different infrared setups..

The keys are reported correctly, but buf is always 0xfe instead of
and there is no difference whether I press a button, hold it, or release it.
Syslog keeps reporting the debug message with the last pressed button.
How can I detect if there is a key pressed?
I don't have experience in writing drivers, should I sniff what the
drivers does? If so, is there a simple way to sniff i2c communication on the
remote sensor address (0x8e in my case)?
Many thanks for all the work you've done on making the em28xx driver :)
