Software to customise this USB PC Remote Control
Solution 1:
It is not an infrared receiver alone, but an infrared receiver coupled with a chip which translates IR codes received to fake keypresses/mouse moves and sends that using standard HID protocol. Thus, it looks like a Human Interface Device and could only do things the keyboard/mouse can, and AutoHotKey should work fine. You can check what keys are reported to the PC, you can try to use this application, and then write an AHK config.
