Any pointers to the bulk/interrupt issues? Was it a general issue, or
related either to
at91-ohci or ar9271?

As far as I've been able to find out, I've got the latest firmware
(check again with linux-firmware).
I've also tried with the master from open-ath9k-htc-firmware.

Is this based on the use of at91- SoC, or based on the ar9271?

The primary use case is to run as a client, though there will likely
be some instances where it'll
function as a AP. (Though primarily for M2M communications), thus
pretty low traffic.

Cheers,
Anders
