I have spent some time trying to get the data transfer working between the Palm Desktop 4.2.1 on my Mac and my Sony Clie. After one of the latest OS X updates (I don’t know exactly which one), I started get the error message _Transport Monitor Could not complete your request (16)_ each time the Mac booted and I couldn’t activate hotsync from the Palm Desktop hotsync / setup menu. Every time I set hotsync to _active_, the error message flashed up and the radio button flipped back to _disabled_.
I didn’t find any useful information in Google – most people with similar problems had had success after completely deleting and reinstalling the Palm Desktop, but this didn’t work for me.
I finally discovered that if I disabled the usbmodem_port under _connection settings_ (under hotsync / setup), I could activate hotsync and synchronize normally. After one successful synchronization, I was able to reactivate the usbmodem_port with no further ill effects. Hopefully this might help anyone else with a similar problem.
Thanks! I was getting really #%#%%$. Now it works.
I have a Palm Tungsten T2 and this solution does not wotk with it. Anyone have a solution when using a T2?
