[sane-devel] HP 7450C libusb problems

[George Garvey]

   I'm getting a lot of problems with Fedora kernels 2.6.5-1.358 and
2.6.6-1.422 and this scanner.

   These are with Fedora sane-backends-1.0.14-1. I replaced the avision
files with the latest from Rene's SVN yesterday and rebuilt the RPMS. These
messages are from after using this newly built RPM. The problem was
happening before, with the standard RPM from Fedora. This is what prompted
trying the beta version.
