There does not seem to be proper firmware support for the chip.
According to mainline code, it should be loading firmware
ar3k/AthrBT_0x01020200.dfu. But the firmware download times-out.
Not sure whether setting "driver_info = BTUSB_QCA_ROME" as suggested in
http://marc.info/?l=linux-bluetooth&m=144633933801493&w=2
would work either. The rom version returned by this chip is 0x1020200.
This version is not present in qca_devices_table, which again will
result in error.
