I just have to say that the usb drives are working fine here. Is it possible that you had a bad upgrade of hal? or maybe the hal daemon isn't running?
Also the "unknown error occurred" is similar to what happend with my hard disks until I added them to pmount.allow so I could use konqueror to manage/mount/umount them but the usb drives shouldn't fall into this category either. -- Not possible to mount USB stick after upgrading to kde-3.5.5 https://launchpad.net/bugs/65662 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
