Sorry to hear the IOIO does not prevent USB glitches. And I thought it was the OTG Y-cable method that was to blame. But does the IOIO actually need the main device to run in OTG mode (i.e., being the USB host)?

If you like an older version of Tophat better, you can still use it. I keep the old .apk files just in case. Of course you do then give up some improvements done in the more recent versions.

A third way is via an "IOIO box" but that seems overkill to me.

Compared to buying a $1000 phone to try to get enough brightness, seems
like a terribly minimalist solution to me. I'm using IOIO-OTG and have
a secondary input wired to give a big PF display. Worked great for a
while, then TopHat dropped the capability out of current releases for
some reason. Maybe XCSoar still has it, but never liked their UI.

Reliability of the system is marginal, usually takes a couple
unplug/replug cycles of the usb to keep things running on a long flight.
