Hi,
I would like to detect usb removal using electronic circuit. I have already checked the power line of the usb port. The difference in volt and current between the usb stick present on the port or not present on the port is only 0.09V and 500 microamp. So how can I use these values to generate logic 1 (usb stick present) or 0 (usb stick not present) by electronic circuit?
Any ideas???
