Is it a laptop? The BT firmware driver was trying to load AthrBT_0x00000200.dfu file and it got failed because no firmware file was present. But 0x00000200 means fw_version.rom_version which coming from controller chip, however, I haven't seen this version on Atheros chipset. >>>>> >>>>> I'm adding my friend - Rick Huang here.

That's why you cannot bring up your card with ath3k driver.
