Removing the USB device
Always power off the system before unplugging the USB device!
If the USB device is unplugged while recording is active, parts of the measurement data
may be missing.
If the USB device is unplugged and re-inserted for < 4 s while the C 60 is powered up, the
C 60 still records data.
If the USB device is unplugged and re-inserted for > 4 s while the C 60 is powered up or a
different USB device is plugged in, the C 60 restarts. In this case, the C 60 is not opera-
tional for 1.5 s.
When no data on the USB device is recorded:
Configure the measurement label usb_mediastate on a RaceCon measurement view or
on a C 60 display page.
The value of usb_mediastate reflects the operating condition of the USB bus:
State

1: Wait: Device detected
2: Ok: Media installed
