Here are 4 USB devices connected:
1. USB Audio playing sound in the background.
2. Sandisk 16gb flash drive - copying a 1gb file in the background from sdcard to this drive.
3. USB keyboard - typed and entered the command to test USB gamepad (Atmega32u4).
4. USB Arduino Atmega32u4 - running and pressing each buttons. All work well.
Everything works fine. I also have a USB hub that works just fine with similar fe1.1s chip that I use all time with my Pi Zero.
Can you tell me exactly what issues you had with the fe1.1s?
any estimated timeframe the PCB will be available? i was planning on purchasing your 2.2 but i could wait depending on when this one would be available.
