I was sorting through some old hardware, and I noticed that I picked up
an edimax wifi dongle from Amazon or such awhile ago.  I stopped using
it because it's only N and not AC and what for I was trying to do N
isn't fast enough.

Anyway, if all you have is the edimax and a keyboard attached I might
be able to reproduce the error locally on an RPI 2 myself and might be
able to give the owners of dwc2 some debugging info. I have a USB bus
analyzer that I bought a long time ago so I can probably send them
useful packet captures.

Maybe you can e-mail me your build .config file and I'll see if I can
reproduce the issue.

The edimax wifi dongle I have has the module number: EW-7811Un.

I'm assuming nothing is special about the keyboard and the RPI 2,
