I can see what's going wrong here.  In the previous version of the
package I changed the controller (RT) revision checks in rt2500usb and
rt73usb so that they would each reject devices that the other should
handle.  (Normally the device id table determines which driver should be
used, but at least one device id has been used for devices with
different chipsets.)  A similar change was then made upstream, but it
looks like the check was initially reversed in rt2500usb, resulting in
this error.  This has since been fixed upstream.

I will probably make a new upstream snapshot, as there are some other
significant bug fixes in it.  If upstream isn't stable enough I will
just patch this in the Debian package.  Either way, this should be fixed
soon.

Ben.
