How to wakeup PC?

Sorry, what I have posted is NOT correct. I've re-read the spec and the resume signal is a differential "1", not SE0. The code should therefore look like this:

Code:

    cli();
    USBOUT |= _BV(USB_CFG_DPLUS_BIT);
    USBDDR |= _BV(USB_CFG_DPLUS_BIT) | _BV(USB_CFG_DMINUS_BIT);
    _delay_ms(5);  /* spec says min 1 ms, max 15 ms */
    USBDDR &= ~(_BV(USB_CFG_DPLUS_BIT) | _BV(USB_CFG_DMINUS_BIT));
    USBOUT &= ~_BV(USB_CFG_DPLUS_BIT);
    sei();

You must generate a USB reset condition to wake up the PC. This is done with

Code:

    usbDeviceDisconnect();
    _delay_ms(10);
    usbDeviceConnect();

You should only generate the reset if the PC is really in sleep mode. You can find out by checking for start of frame pulses on D-.
