I have: * a genuine Saleae Logic 8 connected to a USB 3.0 port -> Intel Corporation 7 Series/C210 Series Chipset Family USB xHCI Host Controller (rev 04) * Ubuntu xenial kernel version: 4.4.0-64-generic * Lenovo W530 After plugging in the Saleae logic into the USB 3.0 port I am able to acquire data once from the LA, any subsequent attempts result in no data being acquired. It is possible to "unlock" the probe by doing an acquisition at much lower sample rate, resulting in the ability to do one more 24m sample rate acquisition. I have also tested the exact same setup with the proprietary Saleae Logic software. It works with no problems all the time every time for 24m sample rate acquisition with arbitrary length. (I have tested up to 10s acquisitions with no problems) When using the USB2.0 port on the same machine the acquisition is more reliable. It works everytime when using the sigrok-cli tool and most of the time using PulseView (but not everytime, it is not a deterministic behavior) Let me know if you need more information. The session logs can be found in the following gist: https://gist.github.com/esden/5a5c3edc1bf34ffb6953031c4189c3db
