If you can`t install drivers for your "Moto" - try to edit your registry.

Let`s start
1. Go "Start" - "Run" - type "Regedit" - Click "Ok"
2. PC will run RegProgram and you will see window with a lot of RegBranches
3. Go: "HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Enum/USB/"
4. Now you should give permissions for editing this RegBranch (click right mouse button on "USB" branch - "Permissions" - "All" - "Full acess"
5. There are some braches at "USB" branch starting with "Vid_22b8&" and now you shoyld find a branch which have a "Servise" branch and change parameter "Service" to "usbhub"(without commas=)) and parameter "ActiveService" to "usbhub"
6. This is all! Restart your PC
