Comment 1 for bug 930460

According to that debug output your device is not
being detected as disk. calibre can only connect to devices that
are detected as disks by the operating system. If your device
has an internet connection, you can connect it to calibre
wirelessly using the calibre content server.

See
http://manual.calibre-ebook.com/faq.html#how-do-i-use-app-with-my-android-phone-tablet
for exmples of how to connect wirelessly to Android devices.

Ask on the calibre
forum at mobileread.com for more help with using the content
server.
