Unfortunately I have to make deeper investigation of problems so I need someone who will be able to help me to study FreeBSD USB stack.

Some useful tools:

- usbdump can dump all traffic.
- usbconfig can dump all config and device descriptors
- webcamd can be compiled with debugging. Maybe an error is printed.
