The short answer is sane is out of date and needs to be recompiled since libusb0 no longer exists.
Chris Here is what I emailed someone else wrt issue: Normally a library is named something like libusb and major sover of 0 so you have libusb0. However as I just recently noticed in libusb's case the library name appears to be libusb-0.1 with sover major of 4. I didn't see any other libraries that were like that at the time so I used libusb-0.1-4 as the name. ex) /usr/lib/libasound.so.2.0.0 - package name libasound2 /usr/lib/libusb-0.1.so.4.1.0 - so I picked name of libusb-0.1-4 I suppose I could have named it libusb-0.1.4 but if I change it now it will be considered new again and dinstall won't put it into sid until someone manually adds it, which in libusb-0.1-4's case took over a week. Then everything will have to be compiled against it again. If I had simply called it libusb4 like some other packages seem to libsigc++0 for example, when libusb upstream decides to call the library libusb-0.2 with major sover 4 I would have a problem, since the old package and the new package would be called the same thing.
