Hi,
Thank you for testing this.
I could not reproduce issue 1 locally with my MX Keys for Business, but
I applied your fix since it also works on my hardware. Either the
different keyboard models behave differently, or something differs
between our setups. I folded it into the existing interface handling to
keep the code smaller.
I also noticed that my older Lightspeed receiver exposes interfaces 0
and 1 as boot keyboard and mouse interfaces too, while only interfaces
>= 3 are treated as generic HID. So Bolt appears to need different
interface handling from the existing Lightspeed receiver path.
Issue 2 was easy to reproduce, and I applied your fix more or less
verbatim.
I will send a v2 patch shortly. I would be very grateful if you could
test it again.
Regards,
Erik
