PCSU200 shown as "unknown device"

On my Windows 7 machine (and another Windows 7 machine) the PCSU200 is displayed as “unknown device” in the device manager. If I use other USB ports it is the same message.

Has anyone a suggestion what I can do.

Many thanks in advance
Thomas

The USB cable may be defective - you may try with other cable if possible.
Have you tried to install the Windows 7 driver for the PCSU200?

If still no help, then this may indicate the PCSU200 is defective and you have to return it to your distributor for inspection/exchange.

I checked it already with a different USB cable but it was not working.

I will send the device back to the dealer for inspection.

Thank you very much for the reply.

Did you load the drivers?
