G15 on Linux

Hi!

I'm currently trying to get the Microsoft Sidewinder X4 working in Linux. So, I came across libg15. G11 / G15 and X4 are really similar to each other, including 18 programmable keys (S1-S6 x 3), 3 banks and a record key. However, the X4 doesn't send out any scancodes, afaik the G15 doesn't too (is that right?). The problems seem to be the same, so I thought about modifying the code, so it fits the Sidewinder X4. Even after some hours of research (in libg15, g15daemon, g15macro), I wasn't able to find out where the USB Raw Data got translated into scan codes or keycodes.

Here are my findings so far about the Sidewinder X4:


Microsoft Sidewinder X4:

Status
_______________________________
Bank 1: 07 04
Bank 2: 07 09
Bank 3: 07 11
Auto: 07 0A
Record B1: 07 64
Record B1 (blink): 07 44
Record B2: 07 69
Record B2 (blink): 07 49
Record B3: 07 71
Record B3 (blink): 07 51

The "bank-switching" (like M1-M3) is a simple procedure:
1. You press "Bank Switch" - keyboard sends "01 00 00 00 00 00 14 00" # 8 bytes
2. "Get Status" request
3. Return actual status (e.g. 07 04, Bank 1)
4. Send 07 09, so keyboard switches to Bank 2
5. Keyboard sends / receives (?) "01 00 00 00 00 00 00 00"

So, is there someone who can give me any advice?

Thank you for your time,
