In Ubuntu 11.04, I unwisely right clicked and "safely unmounted the drive" of my Sony HDR-XR150 connected via USB. Now, when I plug my digital camera into my computer via USB, Ubuntu either doesn't register the new drive, or flashes the "recognition and choice of what to do with the USB drive" screen briefly.
Please help.
FYI, I ran dmesg with the following results:
