Boot camp and dual usb2 controller

i have a macbook pro i7.it has 2 usb port. each port has different usb port on mac os.i use parallels to run windows on mbp. with parallels there is just one usb2 controller. i need 2 different usb controllers. in windows device manager i must see 2 different USB2 Enhanced Host Controller.

is there anyone having 15'' macbook pro with 2 usb ports and using boot camp for windows 7? can you check if you see 2 different USB2 Enhanced Host Controller on your device manager. can you check it by selecting "devices by connection" from view menu and open ACPI x64 based PC/PCI BUS.
