I’ve been playing with a new Saleae Logic (8 channel version) on my Dell laptop. Had quite a few problems with the software locking up. I started moving the Logic between different USB ports, to find the Dell 14z has two types of USB ports. The Logic will not work with the two ports marked SS (for Super Speed part of the USB 3.0 architecture). The Logic runs fine on the USB 2.0 port. I don’t know where the problem is, but at least it works in the correct port.
For the money, the Saleae is an amazing piece of equipment. I would recommend buying from Amazon here. There appear to be a bunch of knockoffs being sold from China at much cheaper prices. The spelling of Saleae is odd enough that it is being forged.
