Wake on USB from a USBUART
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?
