help for understand the usb calls:

[GAURAV GUPTA]

 Hi all,

My name is tarru .i am trying to understand the usb call .

and currently i got struck and i would like to know the difference
between  functions.


usbd_transfer()

and

usbd_do_request()

are we doing anything different ? .i  confused since in both cases we are
transferring/queering for data to usb device

Please let me know if anybody can help on this

Thanks,

Tarru
