USB Logic Analyzer: Pulseview "fx2lafw: Failed to open potential device"

Was this ever resolved or replaced? I’m having a similar error (Failed to open Device, generic/unspecified error) with a brand new fx2la from SparkFun.

I originally tried installing it on Linux, but could not get it to open in PV. After hours of troubleshooting, confirming driver locations and udev rules, I eventually have up and switched to Windows 10 laptop. Unfortunately not having any better luck.

After initially plugging in the device and installing the Zadig drivers, going to Pulse View and connect to Device, fx2lagw (generic…), USB, scan, I hear Windows indicate a USB disconnect/reconnect and the Device shows up in the box “Saleae Logic with 8 channels”.

However, from here, no combination of reinstalling Zadig drivers or simply selecting Ok send to work.

Detailed PV log show the frontage file found, uploaded 4096 bytes, then uploaded 4024 bytes, a few more lines, then “Device failed to renumerate”.

At this point Device manager shows the Unknown Device #1 with status “this Device cannot start, an invalid parameter was passed to a service or function”.

I think I’ve been through all the t shooting suggestions linked here, plus several others I found in Google, but cannot get past this.

Can you provide any further support?

Thanks!
