Hi Hector,The Atheros firmware download driver is not dependent on HCI USB driver. This driver is needed to complement any Atheros driver like BT_HCIUART_ATH3K.

How can an USB driver work with an UART driver? If you do not want to depend on BT_HCIBTUSB then that is fine, but at least you need to depend on USB.
The thing is I have an Atheros AR6233 chipset which has wireless and Bluetooth. Bluetooth part in this chip operates as a UART. The driver for this is hci_ath.c but I also need to download the firmware to the chip, and for this I need to compile ath3k.c. However I don't need BT_HCIBTUSB. But you are right, looking at the source code of ath3k.c it is calling usb commands, so it needs to depend on USB at least.
This brings an interesting question: shouldn't the firmware download part be isolated from the USB driver? After all, I want to communicate with a UART bluetooth chip.
