Calibre 0.6.26 worked fine on my Karmic Ubuntu Desktop (9.10). It notified me about the new version so I did my usual binary install from the "Download Linux" page and 0.6.27 will no longer work. It errors with the following messages:

davidm@dm-lappy:/opt/calibre$ ./calibre

Ubuntu does not seem to have the libusb1 library in Karmic. Is it possible to reinstall the prior version that worked well for me? Or can someone point me at where I can get this library?

Thanks,

David
