I've had the same problem with the ASUS IR reciever that came with my
mini-ITX motherboard. The USB HID driver claims it and it won't output
any data for other remotes, and even some of the keys for the bundled
ASUS remote. the lirc MCE USB driver won't claim it, even when I added
the USB IDs to the driver sources. Apparently some vendors are
describing their products as "MCE remotes" when they are nothing even
close to an actual genuine Microsoft/Philips MCE USB IR reciever.
My solution was to go on ebay and buy one of those HP branded MCE USB
remotes selling for around $20.00. It also capable of sending IR as
well. Buying a USB receiver that also has an IR sender usually
guarantees that it has a raw mode and is not HID only. It works with
generic remotes just as the serial receiver did. The bad news is all
the sellers of these remotes are in Hong Kong and it takes about a full
month to arrive.
