RC5 specifies 5 address bits and 6 data bits.

Old drivers ignored the upper 3 address bits and used the lower 2 address
bits plus 6 data bits for the keycode (0..0xff).

Recent drivers use only 6 data bits for the keycode (0..0x3f).
For maximum backward compatibilty all address bits are ignored by 
default, i.e. the driver listens to *all* addresses.

Pass the '-a' parameter to av7110_loadkeys and the driver will 
listen to the specified address only.

From DVB/apps/av7110_loadkeys/README:
| If you have two or more devices which use the same IR protocol,
| you should specify the -a or --address parameter. If the parameter
| is omitted, the driver listens to all device addresses. Some examples:
|
| Listen to *any* IR transmitter with uses the RC5 protocol:
| # ./av7110_loadkeys hauppauge.rc5 > /proc/av7110_ir
|
| Listen to RC5 transmitter with address 2:
| # ./av7110_loadkeys -a 2 hauppauge.rc5 > /proc/av7110_ir
|
| If you don't know the correct value for the -a parameter, take a look
| on the debug output of the driver (see below).

HTH,
