USB-UIRT Forum

Hello Everyone,

Although this isn't exactly about the USB-UIRT, i was wondering, what is the exact signal/signal sequence that must be sent over the USB port in order to wake a computer? USB-UIRT has the option of programming codes that will act as wake commands, but my question is, what if i wanted to incorporate that same functionality on another device (such as a pda) that's connected via the USB port while the computer is in an S3 (Standby) state?

Thanks in advance,

You'll want to check out the USB spec. This requires manipulation of the D+ and D- signals on the USB bus as well as the USB driver telling Windows to enable wake-up for the device.
