does this unit do synchronous capture and generation ?<br>

Even if it works under Wine, it will likely have issues due to not being able to transfer at full USB speeds.<br>
<br>
The Saleae kit is good. Anyone who rips them off is scummy IMHO.<br>
<br>
I have an old Salaea (8 chan/24Msps) and have recently bought a DigitalDiscovery from Digilent because I needed some more channels and more speed (I needed up to 100MHz, but this goes up to 800MHz).<br>
It can also generate waveforms.<br>

<br>
It also works under Linux. Not nearly as pretty as Saleae, but did the job.<br>
<br>
It stores samples in the onboard 2Gbit DDR which limits the sample depth to a 64Msamples or so.<br>
<br>
What is really neat about the DigitalDiscovery is that it comes with a C/C++ + Python API that allows you to program up "test scripts" etc.<br>
<br>
For example, I needed to capture data into files then run some FFTs etc. All very easy, scripted and allowed me to re-run tests etc without messing about clicking the UI hundreds of times.<br>
