Technical discussions around xCORE processors (e.g. General Purpose (L/G), xCORE-USB, xCORE-Analog, xCORE-XA).

Hi. Try the USB Mouse IP by XMOS that is a High Speed example use of the USB Mouse HID model. The project builds and acts like a mouse that keeps looping the mouser pointer in a square shape.

Does this IP work on your box? Once confirmed, remove and redock onto your MAC USB port. Curious to hear the status.

That one works every time. 20 redocks on each USB port on both Mac and Windows without any failures.

Got to the bottom of the issue. Seems there was a bug in the MIDI code that was causing the USB to crash. All is well now but thanks for the help.
