<whitequark> cyrozap: oh that's fascinating, didn't know about the Fresco Logic one
<cyrozap> I originally was looking into it because I wanted to be able to record a bunch of OTA TV channels simultaneously (20-40 Mbps/channel), and wanted to do it all over a single USB 3 connection without compromising on any USB 2 bandwidth. But then I realized that, even if the FL6000 hub was free, the cost-per-channel would be a lot higher than if I just bought a few PCIe quad-tuner cards and used a cheap
<cyrozap> PCIe switch (which are plentiful thanks to cryptocurrency miners) to connect them all. So then I thought it might be worth it for connecting a bunch of RTL SDRs at once to have huge combined bandwidth, but one again I realized the combined cost of all those dongles would be a lot more than just a single LimeSDR. So after all that, I sort of lost interest in building a hub with one of those chips, and
<cyrozap> these days just try to make sure any "high throughput" USB devices I buy support USB 3, and if I have multiple high-throughput USB 2 devices, I make sure to connect them to different root ports.
<cyrozap> But now that the Glasgow is using USB 2, and can use most/all of its available bandwidth, it might make sense to build a hub like that.
<cyrozap> Well, I'd buy one, at least :)

<gruetzkopf> my OTA tv recording setup is a bunch of PCI (conventional) DVS-S2 cards the local trash distributor was selling for 2.5€ each
