Victron Interface MK3 to USB device not recognized

Hello all, I just installed a victron multiplus 3000 inverter. I have the Victron interface MD3 to USB dongle and have downloaded the VEConfigure 3 software. However, my windows 7 laptop give me an usb error. "USB Device Not Recognized". Is there a USB driver I need to download? Any thoughts on why I'm getting the error. Also, I've used 2 different laptops...Windows 7 & Windows 10. Thanks

Hello PClarke,

Yes, there is a USB driver. You can access it from inside the "Special" menu of VEConfig.

Then you will need to add it like any other unknown hardware device in your version of windows.

Hi, I am struggelig with a similar issue. VE Congigure cannot indentify my EasySolar 24/3000. I have downloaded the drivers through VE Configure (the only .exe file in that package is called "PL2303_Prolific_DriverInstaller_v110.exe". is this the correct driver?

Also, next step in the troubleshooting guide says: ..Check device manager to see FTDI device in USB or Serial Connections". Sorryy newbie here, I dont really know what that means.. All help would be appreciated..

Ps. I have tested the cable and the device is connected. So, I think it is a driver issue.. P.s. I have Windows 10.

Hi @EspenMatta,

Did the driver install after you ran the .exe file?

Restart your computer, and try again with VEConfigure.

To check the device manager to see if the FTDI device is being recognised by Windows:
