Did you try to understand why the USB hub was not properly detected ? I would venture that it would be of help to improve development experience on your device.
-
Did you consider using a powered USB Hub ?
-
May I recommend to search a bit more ?
That will make your life easier.You did not answer the question related to grabbing the system log.
