As it turns out, this also works for the Dell 410 series cards. Attached is an updated patch to include them.

Hello,
As I've recently discovered, the more recent (Dell Wireless 370+) BT adapters with the latest firmware don't come up in Bluetooth Radio mode. They come up in a HID/UHE dongle like mode before the OS loads and expect the OS to transition the device to HCI mode. Unfortunately, the transition to HCI mode isn't done in the same fashion as the existing switch_hidproxy function available in hid2hci. I'm attaching a patch to hid2hci that adds a function for the expected behavior on these newer adapters.
The device that needs to have the report sent to it is claimed by usbhid at OS load time, so there are some calls in there to release it from usbhid.
I tested this against a Dell 370 BT adapter. This should be the same for the newer adapters (after the 370), but I haven't verified them yet, so there may be an additional patch needed for it.
Thanks,
