The drivers only list devices they support. The drivers is where this
information is stored for the kernel and userspace utilities. Drivers
don't scan buses and don't choose whether to support a particular device
or to leave it to another driver.
Not having some supported devices listed in the driver would be a bigger
problem, because if the driver doesn't know whether it supports a
device, how can more generic utilities know that?

You should talk to hotplug/udev developers about it. The mailing list
is at linux-hotplug-devel at lists.sourceforge.net
Blacklisting the driver doesn't look like a flexible solution. You need
a way to "blacklist" a driver for a device, or better yet, "endorse" a
driver for a device to make sure that no other driver is allowed to use

There is no way such patches will be applied. The fix doesn't belong to
By the way, orinoco_pci only support Prism based cards. I'm not aware
of any non-prism PCI cards compatible or potentially compatible with
orinoco_pci. Any "Orinoco PCI cards" are actually supported by
