Driver Install

Normally, the USB drivers for Windows install when the Logic software is installed, and the product should work when connected. In other cases, such as when using the standalone version of the software, the drivers must be installed manually.

If you are using any of the 2nd generation products (Logic 4, Logic 8, Pro 8, Pro 16), you must use the latest version of the software (1.2.xx) since the previous releases (1.1.xx) did not include drivers for these devices. You can download the latest stable or beta release below.

If you have manually installed the 1st generation Logic or Logic16 drivers in the past, you will need to update to the latest software and then manually install the correct driver again.

The first thing to try is manually installing the drivers, if you haven't already. After that, let's try a "have-disk" manual install.

If that doesn't work, please contact us and send an install log along with details about your computer. The information we'll need is at the bottom of this article.

Method 1: New Hardware Wizard Installation

For the first part, we want to get to the new-hardware wizard for Logic. Please connect Logic and then open the Device Manager.

In Windows 10 and 8.1, you can right-click on the Windows logo in the lower left and select Device Manager.

In Windows 8.0, you can search for the Device Manager from the Start screen.

In Windows 7 and Vista, you need to open the Control Panel, select System, and then click the link for Device Manager on the left.

In Windows XP, you will need to open the Control Panel, open System, go to the Hardware tab, and click the button for Device Manager.

In Device Manager, I'm guessing that Logic will show up right away as an unknown device with a warning icon next to it. Right-click this and select Update Driver.

Select the second option for "Browse my computer for driver software."

Use the Browse button to direct the driver wizard to the Drivers folder, which is located where the Logic software was installed. Make sure the "Include Subfolders" checkbox is checked.

  • If the Logic software is already installed, the Drivers folder is here: C:\Program Files\Saleae LLC\Drivers

  • Otherwise, if using the standalone software, the Drivers folder is here:

    \Drivers\Windows

Click Next. If this fails, continue to the "Have-Disk" method below. If using the standalone software, this step should have succeeded. Otherwise, please contact support if using the standalone software.

Method 2: "Have-Disk" Manual Installation

Next, let's try the "have-disk" method. Close the new hardware wizard, go back to device manager, and start it again.

Before continuing, please make sure you have the latest Logic software version installed. If you are using an older version, such as 1.1.15, the below steps will create additional problems. Please contact support if you are unsure if you have the correct software installed.

Again, click "Browse my computer for driver software."

This time, instead of clicking the Browse button, click "Let me pick from a list of device drivers on my computer."

Next, it will ask you for the device type. Select "Universal Serial Bus Controllers."

This option is only present if no existing driver is installed. If a driver is already installed, this step will be skipped.

Now you will be presented with a window you may remember from installing printer drivers on Windows 95. Click the "Have Disk..." button.

This will open the install from the disk window, which will assume that you have inserted a floppy disk into drive A with the drivers. Click browse, navigate to the extracted drivers folder, and select Saleae.inf.

At this point, you should see either just the device you have connected or both Logic and Logic16. See below for details before selecting the device you are using.

If the checkbox for "Show compatible hardware" is checked, only 1 device should be shown. If it is not the correct device, then uncheck it to see all available Saleae drivers, as shown below.

These are all of the drivers that are included with the latest beta software, which you should see in the list when the checkbox for "Show compatible hardware" is not selected.

Saleae Logic 4 USB Logic Analyzer Saleae Logic 8 USB Logic Analyzer Saleae Logic Pro 16 USB Logic Analyzer Saleae Logic Pro 8 USB Logic Analyzer Saleae Logic Start USB Logic Analyzer Saleae Logic USB Logic Analyzer Saleae Logic 16 USB Logic Analyzer

It's VERY important to select the correct product. Selecting the wrong product will cause our software to download the wrong firmware image, causing undefined behavior.

There is some naming confusion here that I would like to clear up.

If you purchased the Logic 4, the Logic Pro 8, or the Logic Pro 16, please select the driver that matches the product name.

If you purchased the new Logic 8, our logic 8 channel logic analyzer with digital and analog, released in September 2014, please use the driver "Saleae Logic 8 USB Logic Analyzer" and NOT the driver "Saleae Logic USB Logic Analyzer." If you have the original Logic unit, 8 channel, digital only, discontinued in mid-2014, please select "Saleae Logic USB Logic Analyzer" and not the one with the number 8.

The original Logic 16, also discontinued in 2014, uses the "Saleae Logic 16 USB Logic Analyzer" driver and NOT the pro version.
