I bought the Core P5 case and the riser cable was not working. I emailed Tt and they responded via email within three days asking for documentation that I actually purchased the case. Sent it to them. Within 7 days of the first email I now have a new cable. The day prior to it coming in the mail I received a phone call where they told me to expect it the next day. I actually haven't tested the new cable yet as I just got it today and I have been busy but I have to give Tt an A+ for customer support. Im astounded that they got me a new cable this quickly. When they called they just asked that I return the old cable to them after I check the new one. I will do so within the next couple days after I test the new cable. My faith in investing in further Tt products has increased because of the quick response time and support. Thanks. Very happy. 
Also- I am in Thailand right now but used the US email address listed when I sent the original email. 

I would like to give an opinion.
Try to do the following:
1- Unplug the control and Uninstall the program completely
2 - Restart Win10 and run CCleaner to clear the registry
3- Enter the Device Manager and delete all the USBs that are not being used
4- Run the CCleaner again
5- Restart Win10
6- Install the program (without connecting the control) with Administrator Privileges
7- Turn off the PC
8- Plug control into an internal USB
9- Restart Win10
If it does not work, try this:
5- Turn off the PC
6- Connect the control to an internal USB
7- Restart or Win10
8- Install the program (with the control connected) with Administrative Privileges
 
See if it works
This seems to me the same problem that some iPhones have with USB
