>Synopsis:      cu(1) on Alix 2D13 faults when attaching to DeLorme LT-20
USB GPS
>Environment:
        System      : OpenBSD 5.7
        Details     : OpenBSD 5.7-current (GENERIC) #905: Sun Jun  7
09:16:35 MDT 2015
                         [hidden email]:
/usr/src/sys/arch/i386/compile/GENERIC

        Architecture: OpenBSD.i386
        Machine     : i386
>Description:
I have previously viewed the NMEA sentences received by an older DeLorme
LT-20 USB GPS through cu(1).  Trying this again with the latest i386
snapshot generates a fault.
>How-To-Repeat:
Attached to this report is a saved script(1) transcript captured over a
serial port of
installation of the latest i386 snapshot followed by plugging the USB
device attempting
to viewing NMEA traffic emitted by the GPS.  I also include a reboot with
the USB device
attached before repeating the same cu(1) attachment.

trace and ps output is shown in both cases.
>Fix:
Not known.
