On Windows, if you go to the Device Manager you can see which COM ports are actually active, and which one is assigned to the USB-Serial driver. Astro-Physics mounts (and probably all other premium mounts) have a real true actual FTDI chip, using supported drivers. My Mach1 has never once jumped ports on me. These drivers is for all mounts that use the Synta Sky-Watcher SynScan controller, including those provided by Orion etc. It should work with both AltAz and GEM mounts. The SynScan Hand Controller V3/V4 version must be 3.38 or 4.38 or later to get full functionality but limited functionality should be available for all HC versions.
This issue is caused when Microsoft Windows does not properly detect the chipset or videodisplay.
Install Gateway Orion laptop drivers for Windows 7 x64, or download DriverPack Solution software for automatic drivers intallation and update.
Corrupt or missing motherboard or chipset drivers
Download and install the latest chipset and video card drivers. If you or someone you know built your computer, it came with the motherboard CD. This CD contains the chipset drivers. Otherwise, you can find drivers for all the major chipsets on our motherboard drivers page.
Corrupt or missing video card drivers
If installing the latest chipset or motherboard drivers doesn't resolve your issue, make sure you have the latest drivers installed for your video card. For a listing of video card drivers, see our video card drivers page.
Other PCI device that Windows cannot identify
If you tried the above two steps and your Windows Device Manager still contains an Unknown PCI device, likely the device cannot be identified.
If you that the device not being identified is installed, we suggest you obtain the latest drivers for that device. A listing of drivers is on our drivers page.
