Yes. I'm using a DROIDX and running liberty gb. 05. It doesn't happen all the time bit its enough to drive you crazy. My desktop is running windows 7 64 bit. Usually I can get out of it by rebooting my phone and waiting for about 2 minutes after start up before I plug the USB cable back in. It's not that big of a deal for me since I hardly connect my phone via USB to access my SD card but when I do it is very annoying to have to go through all of that.
