SM300 and USB with HP VEE version 7.5

We have communications problems with the SM300. After installing the USB driver from your website,

Windows recognizes it as a "SM300 Signal generator" in the group "Rohde&Schwarz USB Devices".

For labeling the instrument in the settings, use the logical name SM300.

Enter the entire USB address (USB::etc) as SiScan shows it in the
