Re: X10 USB Wireless Receiver

Hello Christoph,

The the 5-byte-codes trancated to 4-byte codes are mostly unique (there are 3 
codes which are also in 5 bytes non-unique). Using only 4 bytes should be ok 
for this remote in PC mode. But in this case the actual_length should always 
be truncated to 4.

What do you mean with:

The remote transmites the codes not via IR but uses an antenna. I think the 
recieved codes are those which the remote sends.
My Remote has two functions. One is to control the mouse with 11 keys which 
send 4-byte codes. Second, the about 30 other keys, which emits 5 bytes, have 
normal TV or REC remote control functions. It might be possible that these 
two groups have different protocols. How could I find out?

Some Examples:
4-Byte-Codes:
00000000142570e0 00 PC_MOVE_W qsonicmr6in1pc
00000000142671e0 00 PC_MOVE_E qsonicmr6in1pc
00000000142772e0 00 PC_MOVE_N qsonicmr6in1pc
00000000142873e0 00 PC_MOVE_S qsonicmr6in1pc
00000000142974e0 00 PC_MOVE_NW qsonicmr6in1pc
00000000142a75e0 00 PC_MOVE_NE qsonicmr6in1pc
00000000142b76e0 00 PC_MOVE_SE qsonicmr6in1pc
00000000142c77e0 00 PC_MOVE_SW qsonicmr6in1pc
00000000142d78e0 00 PC_CLICK_LEFT qsonicmr6in1pc
0000000014307be0 00 PC_CLICK_HAND qsonicmr6in1pc
0000000014317ce0 00 PC_CLICK_RIGTH qsonicmr6in1pc

For this Remote Bits 9-13 seems to be relevant for 4-byte keys (These are all 
4-byte keys)

5-Byte-Codes:
20ee11827d
20ee11d52a
20ee1152ad
20ee11c936
20ee11b04f
Every Code starts with 20EE11 so this could be truncated.

In combination with 4-Byte codes the lowest 16 Bytes are relevant.

The problem is that I could speak only for my remote in Combination with my 
reciever but the driver supports some more...
