Hello

I've connected our Dell 3750W UPS to an ESXi host via a USB2.0 cable. After installing the Dell MUMC application, the UPS is detected but reports 'Communication with device has failed'. 

It's definitely configured correctly on the virtual machine as device manager detects the UPS. I have other UPS's in other cabinets connected in the same way with no issues.

I've tried both the MUMC and ULNM software with the same result on both. I also connected the UPS directly to my laptop to test it with the MUMC installed which seemed to work correctly, which suggests something on my VM or host that isn't right, not the UPS or cable.

Can anyone help with this as I'm running out of ideas.  

Thanks
