Put the attached file driver.py in your calibre installation. On my Win7 installation, if goes in the folder
Code:
C:\Program Files\Calibre2\Lib\site-packages\calibre\devices\android
You will need to pattern-match if you are not running windows or if you have changed the installation folder.
Please do not overwrite any files. On windows, you don't need to, because the existing driver is named driver.pyc. I don't know about other OSs.
Please let me know if it works or not.
[edit]: I had to zip the driver to upload it. Be sure to unzip it.
