I used to be able to connect my Droid Incred to my mac powerbook. A pop up screen comes up and I select "ignore". Afterward, two drive icons would pop up (one for the device and another for the SD card). Now, for some reason, the computer doesn't seem to acknowledge my device. I plug/unplug and switch USB ports but still no go. Device is set for 'disk drive' as default connection type and it's supposed to ask me whenever I connect, but it doesn't. What happened??? Maybe I inadvertently deleted something?
