PC Detection Test
In cases where the software cannot detect the logic analyzer, we need to determine if the PC itself can detect the Logic device:
1. Before connecting Logic to the PC, ensure the Saleae Software is not running.
2. Connect the device to the PC using the provided USB cable.
3. Check if the operating system (OS) detects the device. The steps for this will depend on your operating system.
- Windows: Open Device Manager. Expand the section "Universal Serial Bus controllers" and check for "Saleae Logic X USB Logic Analyzer" where "X" is the specific product version (4, 8, Pro 8, Pro 16, etc.). If "unidentified device" or "Westbridge" appears, then there is a problem with the Saleae driver. In these cases, please follow the instructions in the support article below to re-install your Saleae driver.
- MacOS: Open "System Report" by opening the Apple menu and selecting "About this Mac," and then select "More Info..." Afterwards, scroll down and select "System Report..." In the new window, select Hardware > USB > check for "Westbridge" in the treeview. Again, please make sure the Saleae Software is not running running when checking this. Otherwise, the "Westbridge" device will not appear with the relevant information we are looking for.
System Settings > About > General window
- Linux (Ubuntu): Run
lsusbfrom the command line. Check for any device name containing "Saleae" or a VID and PID that matches one of our Logic products. You can refer to the VID/PIDs of our devices in the support article below for reference.
Linux Terminal - lsusb
4. If the PC detects the Logic device properly, open the Logic software. If the Logic software still does not detect your device, then the hardware is likely OK and this may be a software issue. Proceed to Part 2: Troubleshooting the Connection to the Software, found in the support article linked below.
