Please post the diff, so it can be integrated into -stable!

have you put the newly-built module into the right directory?
modprobe only takes modules from the kernel's module directory
(which is normally /lib/modules/$KVER/kernel/...)
you can verify that by calling modinfo p54usb and
check if there's a line usb:v413Cp5513d*...

please don't use "iwconfig". WEXT is obsolete, you can find a
nl80211 replacement "iw" right here:

No need for a reboot, if the correct module is loaded the device
should be recognized instantly... (or as soon as it is replugged.)
