My 2nd gen shuffle still works fine with the lastest iTunes and latest Mac OS X. Did you only update iTunes when this problem started, or was it both iTunes and Mac OS X?
As a test, I woud disconnect all USB peripherals (except for standard keyboard and mouse if desktop Mac), and connect the shuffle to a direct USB port. There may be some odd USB device conflict.
Another test, to help narrow down possible causes, is to create a new user account, in System Preferences Users & Groups pane. Log out (don't use Fast User Switching) and log in to the new user account. Try using iTunes with the shuffle there, to see if it works better. If that helps, the cause is something in your current user account. If the problem is the same, the problem is something that affects the overall system or hardware.
I just noticed that your profile shows two Macs. Do they both have the same Mac OS X version and iTunes version, and does this problem occur with both Macs?

Thanks for your response. I updated to 10.7.4 in May; iTunes 10.6.3 on June 11.
No other USB devices plugged in.
In a clean test user account, same problem occurs.
Same problem occurs also on a 21.5 late 2009 iMac running same configuration (os 10.7.4 and iTunes 10.6.3).
Restoring and syncing this shuffle with a mid 2007 macbook running os 10.6.8 and iTunes 10.6.1 seems to run fine.
After restoration on either of the Lion machines, if I copy 1 Podcast alone to the shuffle, some of the time, but not all of the time it will copy successfully. The next copy fails. Attempts after restoration to copy multiple items fails also.

Other sync methods, such as using Autofill from a playlist, also fail? Does it make any difference, if Enable disk use is checked or not checked, on the iPod's Settings tab (in iTunes)? With disk use enabled, do you get any errors if you copied some files using Finder to the shuffle (as a "disk").

After restore auto fill randomly worked. Could not change anything after that.
Another restore, enabled disk mode. Was able to put a couple small files on the shuffle.
After that was able to select music or podcasts and sync normally.
Thanks very much for your assistance.

Great! It would have been nice to know what the actual cause was...
Be sure to remember to delete those "small files," or they'll sit there, taking up space (even if you disable disk use)...
If the problem is something specific like, disk use must be enabled for your shuffle to work with your Mac config, that should be reported to Apple as a possible bug.
