Hi
As this is USb IP, it should be on fpga board as u r in testing phase, am i right?
which usb speed u r working with, i mean which device HS or FS??
How ur taking care of initial reset condition... I am assuming that u r working on device side... i.e. u r implementing device..
Added after 38 minutes:
And if u r working on HS...just check this out
considering ur device is self powered. n say u have connected usb cable to host port (means cpu usb port in simple words) so here ur initail reset from host comes into picture (i am taking abt initial reset betn host n device) so just check that CHIRP condition. u might have designed state machine with proper timings.....here timing is very imp....so according to clock freq u decide proper time.....
i think this helps u...
Regards.
