Do you see the problem with ghoto2-2.0-4 and libusb-0.1.5-3? You don't mention which libusb version you were using. libusb-0.1.5-2 exhibited this bug, but 0.1.5-3 was meant to fix it (and did for me).
I *believe* that I was using libusb-0.1.5-3. My system had been upgraded from RH7.2 to RH7.3, and libusb-0.1.5-3 is in the upgrade log, so I must have had that installed. By the time I had fixed the problem and decided to bugzilla it, I had collected the rawhide src rpm, compiled and installed, so I no longer had an audit trail. That is why I didn't say explicitly that it was libusb-0.1.5-3 which failed. I can't see how it could have been anything else in view of /root/upgrade.log. ael
I think the current release works then -- please re-open if not.
