kern/70523: umct sending/receiving wrong characters

[Brian Candler]

[Aside]
My Vaio, which was prone to freeze up completely with the other (uplcom)
USB->232 interface, has a UHCI USB controller. I applied the following two
patches to the base 4.10-RELEASE:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/usb/uhci.c.diff?r1=1.40.2.14&r2=1.151
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/sys/queue.h.diff?r1=1.54&r2=1.55
and the uplcom device seems to work now. Hasn't had much testing, but I'm
hopeful that things will be happier in 4.11-RELEASE :-)
