Look, support for Ralink chipsets is a mess. They are supported by too sets
of drivers - Ralink's ugly as hell but working staging drivers (rt2860,
rt2870, rt3070, soon rt3090) and properly developed but lagging rt2x00
drivers (RT2400PCI, RT2500PCI, RT61PCI, RT2500USB, RT73USB, RT2800USB).

Theoretically my WUSB54GCv3 is supported by RT2800USB (which was added during
2.6.31 merge window), but it doesn't work. With tiny patch added to rt3070
(just usb id) my card works. Some day rt2x00 drivers will be better than Ralink's,
but right now they are not.

So I wouldn't like to encourage any of them. I just wanted to fix clearly
wrong help text which stated that rtl8187 (Realtek's chipset!) supports
all WUSB54GC cards.
