• Saleae USB Devices Driver

Each Logic analyzer contains USB device identification information. If the memory that holds that information fails, the device will start to enumerate as a Cypress development kit with the default Cypress VID and PID for that part. Here are the correct VID and PID pairs for each products found in the Saleae drivers. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update, or contact the device manufacturer. I’m Moli, your virtual agent.

The Saleae Logic is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate.

The unit itself is very small, and has a USB 2.0 port connecting it to a PC (and powering the unit) and a connector for the 8 + 1 probe set. It is built around a Cypress EZ-USB FX2LP microcontroller — an 8051-compatible chip with built-in USB 2.0 controller. It can sample 8 channels up to 24MHz.

In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.

See Saleae Logic/Info for more details (such as lsusb -vvv output) about the device.

See Saleae Logic16 for the successor product of the Saleae Logic.
