thanx a lot kejian2000
i have just compiled the code the compilation is ok and i understood the control transfert of endpoint 0 but i didn't find the function that send and receive the data i think that you worked in asm MyTasks()???? u understand me i hope???
and i will post my code so if u can read and make me some comment u will understand the type there are two function PutEP1 and GetEP1 that send and receive so the code is from microship but i made some modification and i made an identify.h where i identify the non defined variable but when i test the code it indicate unknown perepherique and i don't know where is the problem!!!
daviddlc if u have some thing give us ;) i will be crazy because nothing work for me :)

Hi,
Transfer is completed by SIE automaticlly.
SIE receives/sends data when it owns the buffer, see the datasheet of 4550.
In my codes, the ep0 is used for control transfer, ep1 is not used, so it's control mode.
Not HID class, just customer.

Added after 27 minutes:

if u only transfer 1 byte, control transfer mode is enough. libusb32 is a open-source usb driver, u can search the key words in google.
