I think I spoke too early. Must have been a snarl up at my end, because even removing the "#" comment sign before "CONFIG_RT2800USB_RT30XX=y" in config.mk doesn't solve the detection problem.

I just concluded a test with today's compat-wireless /April 20/, enabled "CONFIG_RT2800USB_RT30XX=y" in config.mk, but rt2800usb doesn't detect the VIDs and subsequently fails to initialize the device. Adding, however the card's VIDs in the upper portion of code appears to solve the case. I welcome you to test yourself.

The good news is, once we get past the detection debacle the device seems to finally show some life.

Walter.
