arduino uno and usb tethered internet phone conflicting

curently running arduino uno on my hp laptop and it won't let me run the usb tethered internet off an old razor (com port 3) and uno (com port 5) at the same time i have to disconnect the internet to conect the uno on seperate usb ports, any ideas?

Sounds like a limitation of your operating system. It may not be able to communicate with two "USB Modems" (which is what the Uno and your Phone emulate) at the same time.

hmmm, previuosly i had my dell desktop with usb modem connected to it and routed internet through roughter wirelessly to laptop and could hook ardino to laptop and internet at same time, but the desktop with usb modem and arduino at same time would have same conflicts
