USB Connections to Windows

Usually connecting StackShot to your Windows machine is pretty painless, occasionally though Windows will not install the drivers correctly (or at all). If this happens to you follow the steps below to get Windows to recognize your StackShot controller.

USB Connections to MAC

If your Mac has problems connecting to StackShot please try the following. Copy/paste is the best way since the commands are case-sensitive.

Make sure there weren’t any errors reported during those commands. You will be asked for the root user’s password (usually your own).

Give the Mac a reboot and this should take care of the problem.

As of OS-X Mavericks (10.9), Apple has included a partial implementation of the FTDI driver. Unfortunately this driver interferes with proper operation of StackShot. The above commands will disable the Apple driver so that applications such as Zerene Stacker and Helicon Remote can load the proper driver.

When an update comes out for OS-X you may need to repeat this procedure.

If this process doesn’t fix the problem then you may also have to disable previously installed FTDI drivers:

If you ever need to re-enable the FTDI drivers you can issue the following commands:

New OS-X installation instructions for El Capitan 10.11+

Note: this is the only non-temporary method which works on 10.11 El Capitan.

FTDI provides a signed kernel extension (D2xxHelper.kext) which contains no code but acts to prevent OS X from matching an FTDI chip (with standard vendor and product identifiers) with a VCP driver, either Apple’s or FTDI’s. This leaves the device unclaimed, and available for D2XX programs only. (Such as Zerene Stacker and Helicon Remote).
