They don't. There are a whole set of freely available specifications for 
devices (eg USB printers, USB input devices, USB mass storage devices - see 
http://www.usb.org)
However some devices have ugly specs (eg Communication Device Class) that 
manufacturers didn't always like. So manufacturers implemented USB modems 
without controllers (because it was cheaper, and it worked with windows). 
Also, some manufacturers didn't want to be in the commodity market, and went 
for product differentiation.

I take it that you are complaining about your inability to get the USB 802.11 
devices working. They could have been implemented to one of the CDC models, 
but weren't.
