Hi,
thanks for the info, it helped me to find a solution but not sure if it's a
proper one.
Here is the patch i used to fix the problem on FreeBSD 9.1.

Hi,
i have the following problem.
I have a composite USB device with multiple USB interfaces. Some of
interfaces belong to the Bluetooth device and other to the WLAN device.
The problem is i want my WLAN driver to claim only the interfaces which
belong to the WLAN device. But ng_ubt kernel driver claims all interfaces
for itself beginning with the interface 0. Therefore, my WLAN driver
doesn't work if ng_ubt is loaded first.
The second question is, why FreeBSD USB stack calls the match callback of
my WLAN driver only once with USB interface index 0. Shouldn't it call the
match callback for each interface on a USB device ? Linux kernel e.g. does
it per USB interface.

Hi,
If the interfaces are parented to another interface, they are not probed.
Read the UBT specification at usb.org and provide a patch that will only grab
bluetooth interfaces.
