Dear all, I have installed Huey USB using drivers zipped into the package (I must edit the inf file in order to change nprofile /USB to /HMI to load correctly the device drivers). In the system management I can see the driver and the device without any problems. But if I do command dispcal -? Into -c parameters (comunication port) I can see just only 1 (COM1 port) and nothing else. So I can not use my Huey :-( !!!! Any suggestions ???? Many thanks in advance Umby
