I am having some issues with the VF50 V1.1A modues with CE7 1.3beta4 connecting to my PC (Mobile Device Center isn’t connecting, its says “error”). The issue is intermittent, sometimes it connects, sometimes it says error. Also, the issue seems to only occur intermittently for some modules, where other modules always work. I have tested on 2 PCs (Windows 7 and Windows 10) that do not have any issues connecting to other mobile devices.
I cannot replicate the error with other module types, only VF50.
After it says error, if I open Windows Explorer on my PC I can see the device and browse the files.
I enabled the debug logs in Mobile Device Center as explained here:

The last entry in the wmdc.log file is:
DateTime=2016-06-23T21:42:30.0105669Z
wmdc Error: 6 : Caught exception: System.Runtime.InteropServices.COMException (0x80004005):
Unexpected COM exception-2147024894
I have tried disabling the USB high-speed settings. I have found 2 websites that mention the high-speed settings for VF50, but they have different information.
Q: Have you experienced this error with Mobile Device Center?
Q: Can you please confirm which are the exact registry settings to disable high-speed for VF50? Thanks.
