I am stuck too with the exact same problem.
Presently I have installed/unistalled driver multiple times but it is not helping.
Can get adb to see my device. Since adb and fastboot commands are working it is not a PATH issue.
Installed 3.10.1 version of drivers since I am on Win8.
If adb can be made to detect my device .. I can push backup to the internalsd and simply restore the backup from cwm.
Presently my Internal memory is clean and unfortunately this device does not accept sd cards.
