[PD] The dwc_otg.speed=1 issues on RPI with keyboards

[Alexandre Torres Porres via Pd-list]

I need an audio in and I got an imic griffin, it says on pd page i need to
make this adjustment, how do I know if I don't really need to do it
anymore? Anyway, if raspbian has changed, maybe we should update the pd
page about it

I dont mind getting a bluetooth keyboard if I have to, I just wonder if any
should work fine or if there are some issues.

thanks
cheers
