snd_uaudio ugen0.6 device and config descriptor dump

So far I compared with previous version of system where devd successfully
matched the same device to snd_uaudio module (by bus, vendorID, productID as
per usb.conf). Although currently it appears like devd does not support this
behavior because an attempt to reinstate /etc/devd/usb.conf didn't have any
effect.

In addition I noticed a flood of weird uhub messages in syslog such as the
following:
>>>Jan 28 12:41:43  kernel: uhub_reattach_port: giving up port reset - device vanished
But it does not say which port. I am not sure whether this is relevant to this
issue or this is a separate one. As someone suggested I switched the following
config and these log messages disappeared:
>>>sysctl hw.usb.disable_enumeration=1
Also having enumeration enabled makes invocation of usbconfig getting stuck.

Please find the usbconfig dump of device and config descriptors for the
snd_uaudio device in question

Thanks,
Max
