Hi Môshe van der Sterre, Thanks for you answer. This mouse can store keys in their internal memory but can also load profiles from a local file. When using profiles, keys are not stored in internal mouse memory. I had tested it in other PC running Windows and when I disconnected from USB and then connected to my PC running Linux verified that keys where not being detected. Only when I stored the keys in mouse memory (without using profile) I could catch them using xev or showkey. This is why I think that could be a missing feature for linux mouse module.

This means there is not actually a need for a specific kernel driver. I guess it is possible to program the mouse from user-space, with libusb for example. If there is no linux software available that already does this, you will need to do some reverse engineering on the usb protocol used. This can be very simple, very hard or anything in between. I have no experience reverse engineering USB from windows, but you could start by looking at USBPcap or simmilar windows based usb sniffers. > > As for the correct mailinglist, this question would be on topic for linux-newbie as it relates somewhat to driver development, but not the others. > > I hope this helps, > Môshe van der Sterre > > On 12/01/2016 11:57 AM, Samuel Bernardo wrote: >> Hello, >> >> I'm sorry if I'm spamming some lists with this help request, but I don't >> know exactly what's the right mailing list. >> >> I would like to use Logitech G502 RGB gaming mouse with programmed >> profiles from their software, but I realized that generic driver in >> linux didn't support it.
