What does lsusb -v show ? The correct firmware is required, you can find it in: http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=summary Copy the files in ar3k/ into /lib/firmware/ar3k (might be different depending on your distro). Reload ath3k and something like this should be seen: root@linux-test ~# hciconfig hci1 up root@linux-test ~# hcitool dev Devices: hci1 00:03:7F:44:84:8A > Looking back through the ath9k-devel list, I can see that there was some > discussion on this chipset, but it seems that Bluetooth functionality > wasn't tested with it.

Coexistence testing is ongoing and bugs are still being ironed out, but basic support is mostly done. > Aside from the Bluetooth problems, there are also problems with > frequently dropping signals (even when I am very close to the access > point), but right now that's a secondary concern to Bluetooth for me. Can you try with the latest driver (using compat-wireless) and see if the problem persists ? If it does, please post the kernel log with driver debugging set to 0x8f49. http://wireless.kernel.org/en/users/Drivers/ath9k/debug Sujith -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
