Re: [PATCH v3] ath3k: Add support of MCI 13d3:3408 bt device

Hi,

I tried to understand why this "0x13d3, 0x3408" device support
wouldn't go in btusb as it's really close to IMC BT chip found in
Realtek Wifi devices which is on the path to go in btusb [1]

then I guess there is a lot of code that could be shared to support
all IMC usb devices in the btusb module.

Regards.
