Abstract
A circuit configuration for a USB peripheral has an integrated circuit, which has two pins for connecting to two data transmission lines of a USB connection. A peripheral functional information resistor, which is specified as being essential in accordance with USB, is connected to one of the pins. The other pin is connected to the operating voltage via an electrically conductive component. The integrated circuit has an evaluation device, which identifies the USB connection state in dependence on the potential that is present on the other pin.
