can you disconnect all USB devices; check in device manager under USB controller, double click to open each strain make sure all "ghost" USB\serial connections are deleted\uninstalled, reboot the machine properly, (=with power off then ON). Since win7 this error happen, appeared when you can not set COM 2,3,4,5 etc manually. In XP when a device is unattached the driver and the COM is cleared; in later win versions it remembers somehow cause connection problem.
After checking the device manager reboot and win still not sees proxmark, you can use this http://www.libusb.org/wiki/libusb-win32it is reported to fix a lot of USB device connection problem
Thank you I already installed the libusb for Windows, since it happens on both Windows and Linux this is no OS issue.
