lynxis lazus has uploaded this change for review.
firmware: usb: call USBD_HAL_DISCONNECT while usb init to recover from resets:
The firmware doesn't recover from a OSMO_ASSERT() which direct reset the board.
After the reset the firmware will waits forever for the USBD state USBD_STATE_CONFIGURED.
By adding the explicit USBD_HAL_DISCONNECT the board always recovers.
Fixes: OS#5478
