I bought some USB IR using standard Windows 7 driver and works normally with original remote. I want to program Harmony 525 to use it like MCE keyboard (device) but seams that USB IR response only on 48 codes from original remote. My question is:

- Where that 48 remote codes are written, into USB IR memory (chip) or somewhere in PC driver?
- What parses codes into commands, USB IR module or some .sys .dll or .inf file in PC?
- Can I add manually somewhere additional codes for additional commands or not? In other way, can I customize USB IR to responde (because it receives every code, led is blinking) more than 48 programing codes and how?
