Most droid devices no longer support simple Mass Storage
USB access anymore.... Something about their lack of
security... ;)
The best way I've found for accessing my droid devices
(aside from pulling the MicroSD card) has been to run an
FTP server on the device.
With that, you can simply connect with AmiFTP or pFTP and
move files back and forth straightforwardly over your wifi
network.
The most recent FTP server for droid I found was called
"FTP Server (Free)" on the open source marketplace
"F-Droid":

Good luck,
