Description Piergiorgio Sartor 2008-02-22 05:22:32 EST
Description of problem:
First of all, I would apologize in advance if this is not a bug or if it's
duplicated one.
The issue, which could be somehow found also searching around in internet, is
that both modules have same alias for some devices.
There are suggestions around to blacklist one or the other module, in order to
have the proper one loaded.
I could imagine the aliases should be always unique, but I'm not sure.

Version-Release number of selected component (if applicable):

How reproducible:
Well, always, in this kernel.

Steps to Reproduce:
From root shell:
( modinfo rt73usb; modinfo rt2500usb ) | grep alias | sort | uniq -d

Actual results:
alias:          usb:v050Dp7050d*dc*dsc*dp*ic*isc*ip*
alias:          usb:v050Dp705Ad*dc*dsc*dp*ic*isc*ip*
alias:          usb:v148Fp2573d*dc*dsc*dp*ic*isc*ip*

Expected results:
I guess nothing should appear, as per, for example, the pci ralink modules.

listing the ID is both possible drivers is the best alternative we have.  I'm
