[SOLVED] Problems with undefined symbol libusb_set_option in Chimaera release

Hi All,

Thanks for releasing Chimaera.  Upgrade went incredibly smoothly except for my scanner.  When I try to run hp-scan, I get the error below:

roger@aardvark:~$ hp-scan 
Traceback (most recent call last):
  File "/usr/bin/hp-scan", line 40, in <module>
    import scanext
ImportError: /usr/lib/x86_64-linux-gnu/libsane.so.1: undefined symbol: libusb_set_option
roger@aardvark:~$ 

I've tried uninstalling the hplip tools all the sane and libsane packages, etc.  No success.  When I reinstall, I get the above missing symbol.

roger@aardvark:~$ dpkg -l | grep -E "(hp|sane)"

roger@aardvark:~$ 

There was discussion about this on the Ubuntu forums, but reinstalling libsane1-1.0.0 didn't fix it, neither did a forced reinstall.

Has anyone else seen this and is there a workaround?

Thanks,

Roger

Re: [SOLVED] Problems with undefined symbol libusb_set_option in Chimaera release

Found the problem.  At some point in the distant past, I had built libusb and installed it in /usr/local/lib.  With the upgrade to Chimaera, this locally built library was out of sync.  I deleted the libusb files /usr/local/lib and all is well again.
