I have had this problem for a couple of years. Whenever I attach my
Garmin GPS in mass storage mode, no da device is created and the GPS
freezes completely. I have to take out a battery to reset it. I am
getting this with 10-STABLE and 11-STABLE, with a Garmin eTrex Touch 20
and a Garmin Oregon 700. I get the same symptoms in all cases.
The eTrex Touch 20 went through a number of firmware updates. It once
had a firmware that supported mass storage mode only. When I plugged it
into my FreeBSD machine, it worked correctly. After I upgraded to a
newer firmware that gives me a choice between mass storage and MTP, the
above symptoms started. So it is some change to the Garmin USB stack
that causes this. Needless to say, the device works correctly with
Windows and Linux - they seem to have tested that.
I have ehci and xhci in my kernel. If I comment out xhci, the device is
not recognized at all - no dmesg output and the device thinks it has
been plugged into a charger. With xhci, I get the following output
before the device freezes:
