For those interested, the issue was on the HID descriptor, or rather the fact that for some reason the 'feature report' was not liked by hidapi, and I've changed it to an "output report" as follows, now both machines can communicate.
Still, I have s mall issue in which if the report is not read promptly on the RPI, the PC will get stuck until it is read. Not sure why.
