> The problem as I recall first occurred in late January or some time in February when  someone decided to remove large portion of the VIDs from the code because of driver collisions and I suppose the purpose of it was to reshuffle VID tables and insert some sort of order. Since then, compat-wireless does not automatically provide drivers for the rt307x via rt2800usb. To this point, only manual modification and inserting of the VIDs above solves the problem.

As I mentioned, I am not experiencing this. See attached the modinfo output for the modules that I built with a clean compat-wireless package.

The only way I can explain this is that on your system, for some reason, changes to config.mk are not picked up by the build system.

Can you try removing the include/linux/compat_autoconf.h file (from the root of the compat-wireless tree), and then run a make clean, followed by a make.
