Re: [Gpsbabel-misc] Garmin Venture HC on Mac OSX

[Robert L. <rob...@gp...>]

There seems to be something unique about the Venture HC on Mac and Linux.  I
have a request in with Garmin, but haven't heard back from them yet.  I
suspect there's something in the firmware that is different than the other
devices but that happens to work with their Windows driver.

Apple's USB stack can become unstable when dealing with naughty USB
devices.   Once it gets grumpy, unplugging and reconnecting the device will
usually restore sanity.   It usually won't "heal" on its own.

Joe, does it ever work for you?  If you detach and reattach the device, does
your debugging trace end in the same spot as the other reporter of this
problem?
