Ok, it turns out that it doesn't fail all the time, but only sporadically.
So increasing the number of retries fixes (or at least works around) it.
OK, feel free to add ~3 retries inside af9035_ctrl_msg() i think.
You didn't mention if error is coming from af9035 firmware or from USB
stack. Just for the interest...
No idea why this behaves differently from fc0011 on Hans' driver, though.
Maybe some delay or there is retry on error logic.
