Media key regression from 0.63 to 0.64

[alankeny]

I need to report a regression between release 0.63 and 0.64. On July 22nd I reported in the "Tester Wanted" discussion that everything was was working with my setup except the media keys on the keyboard including mute, volume up, and volume down. Shortly after that you made a change, and all my media keys started working with the deskhop-test2.zip version posted in that thread. They continued to work properly through the 0.63 release.

With the 0.64 release my media keys are back to the previous behavior. They result in mouse movement and sometimes right-clicks instead of sending mute, volume up, and volume down. Please let me know if you need me to collect any information from the 0.64 release. For now I've gone back to 0.63.

Thanks so much for continuing to develop this project!

That's odd because no part of the code that touches those was changed. Can you perhaps do usb hid descriptor dump and paste here, I'll try to check what the code might be getting confused with...

[alankeny]

I'm not sure which one you need, so I'm sending three descriptor dumps:

• Unifying Receiver directly connected
• DeskHop switch running 0.63
• DeskHop switch running 0.64

Let me know if you need anything else.
