I have the same issue with a Scimitar RGB Pro, it's also probably the reason why macros on my keyboard have never worked.
This is the message in device manager:
Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer.
I only got the mouse today and have pretty much wasted the day trying to get it to work. The only way the driver works is to quit iCue which isn't viable for me due to the fan/pump/temp settings I have.
