  1. I installed mine to use with a mixing board allen heath qu 32, but it does not work , Do I nee to connect the power cable to make it work ? looks lika a 20 pin, small, flat….or it work withhout ?

  2. Some older PC’s have varying versions of PCI express, from 1.0 to more modern 3.0. PCI express 3.0 is definitely faster than 1.0. Will a PCI express USB 3.0 card be limited by say a PCI express 2.0 slot?

  3. Yes, attach the next available SATA power connector to that input. The mixer’s usb chipset needs a handshaking voltage apparently.

  4. Will a PCI express USB 3.0 card be limited by say a PCI express 2.0 slot? Will it take advantage of all four PCIe 2.0 lanes available at the connector for maximum bandwidth?

  5. I don’t understand why they don’t include the actual USB controller chipset in the comparison, manufacturers lie! I want to see graphs and actual proof of the findings. I’ve seen way too many reviewers who get these cards for free say they do everything they say they do, but come up short when buyers buy them. How can an ASM3142 chip which is a 3.1 version variant have more than 2 ports? the chipset only supports 2, so if you use more than 2 ports at a time you are sharing throughput with another port. Also, 3.2 USB is limited to one port at this time, 3.1 gen2 can support more than 2 ports… Why not list these as what they are 3.1 gen2 cards… Even if the throughput is the same as an actual 3.2 gen1 no need to make it sound better by saying it’s a 3.2 when it’s not. When you hear 3.2, you’re thinking 20gbps, not the old 10gbps that a 3.1 gen2 gets. Just be honest!!
