It seems true.
You can refer any document which tells about the enumeration of USB Device.

Please respond to "ashish

Hello All,
I have a generic query regarding slave usb functionality.
I understand that embedded firmware does all the functions for a
usb device.
but in case if i have to write a slave driver what all steps i
will have to do at high level just for processing a SETUP request
packet by host.
i assume SETUP packet is first received in receive buffer.
then slave driver should pick it up , interpret it and ask the
underlying hardware support to supply the device decriptor which
may in turn deposit the response bytes in transmit buffer.
consequently it would be scheduled to be transferred out of port
on wire.
is this true by and large ?
or i am missing some intermediate points.
Best Regards
Ashish
