USB storage devices not shown in Path Finder, yet function, and show in System Information?

This problem only started after installing Path Finder. However it shows up in both Finder and Path Finder.

Occurring starting about last month, this has gone from a seldom, to all the time situation. (Oddly, some times Findner would display and Path Finder would not, and sometimes the reverse as well.) Plugging in any USB memory device either directly to the computer, or with cables, will allow the files to be accessed/changed/deleted by programs, but the device with it's files will not show in finder. The device shows in System Information. I have set Finder to show everything, but they no longer apear.

Before failing entirely, I would sometimes have the device show for a short time, then get an "Improper removal" error, without touching the device, after a few moments. All these memory devices still function properly when used in external devices and when direcly accesed by software. All other USB devices function normally. All memory devices function normally with other equipment. Memory devices function as expected when accessed by software. System Information finds them. This is not dependant on a specific USB port.

I have tried this with a new user account, and also tried deleting the "" file preference files located in the Preferences Folder. The preferences are re-set, but the drives are not listed.

Reproducible from a fresh reboot, with no programs running. No diagnostics indicate any problems. Mac Mini with Lion with all updates.

    In the lower left corner of the window, click on the grey gear. Go to the Hide Section option and see if Devices is checked. If so, uncheck it. You could also try making a new side bar by going to the New Sidebar option. Just name your sidebar and everything should show up.
