unable to mount any device in 1.3

[boscaiolo]

I always upgrade when calibre offers a new version at startup.

Having just upgraded to 1.3, I find calibre no longer detects my sony prst2. Trying to get debug information caused it to completely freeze with 1 process running. It was necessary to force close calibre.

I then tried again with the Kindle 2 keyboard. This also is no longer detected. Unlike the Sony, I do get debug information which shows the mount failed (see below):

The debug info does not reveal where it is trying to mount, so I cannot check for permissions problems.

Any suggestions?

There have been no changes to device detection in 1.3. THat error indicates your udisks is broken, it is preventing calibre from mounting the device. Either fix udisks, or mount the device by hand before starting calibre.

Either fix udisks, or mount the device by hand before starting calibre.

I have never had to configure udisks, and have no idea how it can be broken. I can mount the partitions by hand easily enough, but to where should I mount them? What is calibre looking for? In the case of the Kindle there is only one partition to mount, but the sony presents as three devices. Where should I mount them?

[kovidgoyal]

Mount them wherever you like, calibre will detect the mountpoint automatically. And in a linux distro things can break without you having to do anything at all.

Kovid, thanks very much for your quick response and help.
