yaa i know everything about the 1160 initialisation but the problen is that i am not getting how should i communicate with peripheral device?

how the packets r send on usb lines?

how i should send control transfer requ to peripheral?

means after writing PTD header wht i should write so the peripheral will understand it that it is a device descriptor request?


i have written code to send a device descriptor req to peripheral and it has return a stall but i am not sure that is it going on right track or not.

i am a bit confused abt the packets, handshakes, and frames

i just wanted to now that does every packet from peripheral gets stored with PTD in host? or just data packets gets stored?

plz help me i am in big trouble for this since october...............
