 I have an application where I would like to wake the PC from a USBUART device.

i have read a lot about USB communication and found I should be possible to wakeup the PC with a RING signal send to the usbser.sys driver.

I have downloaded non Cypress device and see the PC is ready to wakeup. I have also connected another device (FTDI device) and let this device wakeup the pc. It's all working.

My problem is now to send a ring signal from a CY8C24894. I have used this command: 


but without the wanted result. 

Have anybody tried to wakeup the PC from at USBUART?

Best regards
