Plugging in a USB hub causes crash and/or uninitialized root port [RPi Zero W]

Open SynthGal opened this issue 1 year ago • 3 comments

Howdy folks.

As the title says, plugging in a USB hub causes the device to sometimes crash/restart, and then report over HDMI that it "Cannot get device descriptor (short)" and "Cannot initialize root port". If I unplug the hub and plug in a keyboard, it then says "Previous attempt to initialize device failed" which makes the device useless until I power cycle it.

The Raspberry Pi Zero (or RPi Zero W in my case) only has one USB port, and my MIDI keyboard doesn't have the controls for adjusting any synth parameters. I would like to be able to plug in a KORG NanoKontrol2 for doing this, but I need a USB hub for that. I've tried several different hubs and they all do this.

Any ideas?
