Soft lock after putting the PDM to sleep

[DFlak]

When connected via USB if you use "sleep" button it will briefly put the board to sleep, then the board wakes up (after abt. 1-2 seconds) but all the buttons are greyed out. Wakeup button does nothing. You need to disconnect and reconnect the adapter.

It may be related to the lack of auto-disconnect, similiar behaviour

I need to add a disconnect after putting it to sleep

@DFlak can you see if v0.1.4 handles this properly? I'm not sure if putting the device to sleep drops the port from the PC.
