Does anybody here used uPSD3234A USB or USB communication? I got the SETUP command from Host controller to setup the new address for uPSD3234A, in USB specification we know that this kind of control transfer consist of two stages, first is SETUP, second stage is status stage(IN). If I use polling method to poll back the status and setup the address for uPSD3234A USB, it works fine, But I tried to do the same thing using interrupt way, but it failed, I am pretty sure that I have got two interrupts from SETUP and IN token, but after I assigned the new address to usb, it didn't accept it, it always keeps default address 00, I lost here, I don't know what happened.

Any idea from you guys?

Thanks.
