Re: Hi all, I'm newbe, so apologize for my stupid questions.

OK.
Where can I find the code where physically the HDC read the packet from the 
control endpoint where HDC sent the setup request from?
I found the interrupt handler for uhci-hdc but inside I cannit see something 
like this
	status = inw(uhci->io_addr + USBSTS);
	if (!(status & ~USBSTS_HCH))	/* shared interrupt, not mine */
		return IRQ_NONE;
	outw(status, uhci->io_addr + USBSTS);		/* Clear it */

made for the control endpoint  FIFO buffer.

If you have siggestions they will be very appreciated.

Thanks a lot and sorry if I profit by your patience.

Best regards
