Problems opening com-port


I have some problems with the XBIB-U-DEV.
when i try to open the com-port i get an error. Than after i reconnect the usb cable, end try it again it functions fine. This is a big problem, because after a restart of the computer i need to reconnect the usb cable.

i tried different drivers but all seem to have this problem.
i am using windows 7 enterprise 32 bit.

Has someone the same problem or a solution?




Uninstall the old drivers and try the latest driver,
