Re: USB host controller and client driver

What is the role of function drivers ?? Are client drivers and host
drivers enough to handle all situations ??

As you might know the USB protocol is asymetric -on one side you have
the USB host and to that you connect USB functions (in your case the
USB function is the USB mass storage device, and the host is your WinCE
device).

Now, due to the asymetry of the protocol (the host polls the
functions), if you want your device to be the USB function (think PDA
connecting to PC) you'd use the USB function drivers and special usb
function hardware rather than USB host drivers and hardware.
