Hi sean sean Welcome to - [Geeks to Go] Sorry for the delay -
What is your definition of [HUB Port]
(1) Do you mean [Root Hub] referred to in [Device Manager] if so then you may need to use an [External Powered USB HUB] that is solely dedicated to [Motorola Razr cell phone]
(2) Do you mean [External USB HUB] if so it must be an [Externally Powered] & dedicated to the [Motorola Razr cell phone]
Regardless of your definition here are some comments -
(1) USB Ports are limited to 500 milliamps
(2) External Powered USB HUBS usually have an [External/Internal Switch] that should be set to the [External] Position to save drain from PC Power Supply
(3) Not all [Native USB Ports] are capable of 500 milliamps
(4) And not all [USB HUBS] are [Externally Powered]
(5) There are [Quality Differences] between USB HUBS Some can handle [Inrush Current] Better than others
(6) If the USB Device is a 500 milliamp device you may have to select a [USB HUB] that was tested & proven to be compatible to [Motorola Razr cell phone]
(7) Laptops have [Power Saving Utilities] that may be interfering with installation They are usually Controlled by [BIOS Settings] ACPI (Advanced Configuration and Power Interface)
A power management specification developed by Intel, Toshiba and Microsoft that makes hardware status information available to the operating system. ACPI enables a PC to turn its peripherals on and off for improved power management especially in portables.
(8) Have you the latest [Drivers] [Correct Data USB CABLE] & Manual Try website -

(9) Do you have an active Account for this service-
(10)- Phone may need a reset Leave Cables Connected Turn Phone [OFF] for 5 10 seconds Then Turn [ON]
That is all the suggestions I have as of now Might want to visit [Laptop Website] and inquire about USB DATA Cable with Motorola Cell Phone Issues -

I had the same problem with my external dvd player for my laptop and all I had to do was replace the cord and the problem solved itself.
