--- Comment #29 from remyvarma@xxxxxxxxx ---
Thank you. Yes it would be great to find the root cause of this. I am happy to
help debug. Two things I noticed. Is it normal to have two messages like this:
[   54.976434] dwc2 ff400000.usb: new device is high-speed
[   55.090994] dwc2 ff400000.usb: new device is high-speed
(I also see the same thing on mine)

And also, I think possibly related to this:

I saw DPTXFIFO 9: Size 256, Start 0x00000123 in my debug logs at some point,
even with that patch applied. I will reenable debug logging to try to find it
