I have installed the lastest PL2303_Prolific_DriverInstaller_v1.9.0.zip on windows 7 64 bits, and I have some random signal on the DTR and RTS pin.
I use the DTR pin to hard reset my circuit.
Under linux I have no problem, but under Windows I see sometimes DTR and RTS go UP and after 2 seconds go Down.
I’ve desactived all the “USB selective suspends settings” and “Allow the computer to turn off this device to save power” in windows.
On the first joined image, the first measure is the RTS and the second is DTR, with 500ms/div

On the second image, it’s with 10s/div
Have you seen the same thing, or have you a solution ?
