BLE to USB switchover interface freeze

[mondalaci]

When switching from BLE to USB, the USB mouse interface often doesn't send reports anymore, but the keyboard keeps working. Sometimes, it's the other way around. Sometimes, both interfaces keep working. The bottom line is that the switchover is quite erratic.

This issue is relevant when switching from the dongle or a BLE host to USB.
