What is my advice to all people in such situations, this is to avoid fiddling with firmware updates, because this will turn in to a brick any copycat produced chip. Self-powered and even low-power devices like USB 3.

December 4, at Do you have genrsys kind of problem? I mean you could keep it and use it as a USB2. If throughput is what matters, look into getting more controllers first!
