[ath9k-devel] EOMA68-A20 (allwinner sunxi a20) 4.7.0-rc2 ath9k_htc "ath9k_htc: Unable to allocate URBs" issue

In case of:
[  147.060165] usb 5-1.4: ath9k_htc: Unable to allocate URBs
you are out of bandwidth limit of you usb root hub.

Any research in this direction are welcome.

In case of:
[   75.816339] usb 5-1.4.2: BOGUS urb xfer, pipe 1 != type 3
the adapter was started in USB 1.0 mode (which is present, but never
tested - so, not supported.). Why it is in USB1 mode - no idea, but it
is already second time i have seen it.

Support for USB1 mode seems to be welcome too.
