dear frebsd-bluetooth@ users

with HPS blessing another updated/cleaned up version of the ng_ubt2
driver for usb2 was committed to -head.

this version should properly handle stalled usb transfers (i.e. the
system should not panic anymore). also the code is now (hopefully)
easier to read/understand/maintain.

please give it a try and let me know if there are any problems. i'm
also interested to hear about your experiences with ng_ubt2 and how it
stacks up to usb1 ng_ubt.

i also would like to thank HPS for his patience while working with me on this.

thanks,
max

URL: http://svn.freebsd.org/changeset/base/187741

Log:
 Clean up ng_ubt2. Get rid of excessive use of NG_NODE_REF/UNREF().
 Make detach() completely synchronous. Properly handle stalled USB
 transfers (use internal mechanism instead of submitting own control
 transfers). Rename/remove a couple of variables and update comments.
 This work was done in close collaboration with HPS.
