Either that or just fix udev-detect prior to trying to load it.

I'm guessing this could be related to a duplicate serial number in the
usb device itself or similar (e.g. lazy manufacturers?). This is why
Daniel asked for lsusb -v output to see what additional details are able
to be used here.

However, I *strongly* advise using the latest release of PA + the
patches on stable-queue. 0.9.19 is quite old now and there are a couple
hundred additional fixes already committed, one of which may have looked
at this kind of issue.
