I followed all of the directions to install calibre and like it so far, but the send to device button is greyed out, I've tried unplugging and replugging the device, to no avail, searching the forums I found a post referring to TTFQuery and attempted to install it, but receive the following error:
error: Could not find suitable distribution for Requirement.parse('TTFQuery')

I tried running prs500 info but it just hangs.

Any suggestions would be greatly appreciated.

Is your 505 being mounted by ubuntu?

Yes it is, also for some reason I have 2 zombie calibre processes.. :S

reboot
