Comment 11 for bug 118205

To clarify some things:

According to README from rt2x00-cvs-2007070304 dependiences for various cards are as follow:

 When loading the modules manually with insmod, you should load them in the
 following order:

 # eeprom_93cx6.ko (optional, only required for pci devices)
 # rt2x00lib.ko
  # rt2x00pci.ko (optional, only required for pci devices)
  # rt2x00usb.ko (optional, only required for usb devices)
 # rt2400pci.ko (optional, only required for rt2400 support)
 # rt2500pci.ko (optional, only required for rt2500 support)
 # rt2500usb.ko (optional, only required for rt2570 support)
 # rt61pci.ko (optional, only required for rt61 support)
 # rt73usb.ko (optional, only required for rt73 support)

Gutsy kernel 2.6.22.7 contains only rt2x00lib.ko, rt2x00pci.ko and rt2x00usb.ko. Enabling e.g. a RT2561 based card requires a rt61pci.ko and a firmware (README again):

 rt61pci and rt73usb require firmware to be available while loading the module.
 The following firmware files are available for each driver:

 # rt61pci
  - rt2561.bin
  - rt2561s.bin
  - rt2661.bin

 # rt73usb
  - rt73.bin
