Aaaand yes! The USB3 header to USB-C works like a charm (10Gbit/s for my USB-C port!).
Instead of rerouting 2x USB3 ports from the back of the mobo, I decided to use a USB2 header -> USB3 header adapter. Basically I downgraded the frontal ports to USB2, but it's not a problem because I use them for my fingerprint reader and the Logitech Unifying receiver.
I also tested the 2x USB3 Type A to 19-pin USB header, and it works as expected.
Hi, sorry to necro a 1yo post, but just wondering whether this setup is still going strong. I'm going to be doing a build in the NZXT H1 with an Asus X570 motherboard, which has only one 19-pin USB header (marked U32G1_12). The H1 front panel has the same cable situation, with one 3.2 Gen 2 Type-C -> Type-E and one 3.2 Gen 1 -> 19-pin connector. If I had realized ahead of time I would have gone with B550. But I do want full connectivity on the front panel because of how annoying the H1 makes rear (bottom) panel access. I don't mind plugging things into the I/O shield and running cables internally. Don't want to sacrifice either m.2.
Am I reading correctly that you can actually combine the bandwidth of two USB-A 3.1 ports using the dual USB-A -> 19-pin female passive adapter, and end up with a 10Gbps USB-C connection? Does that work stably? If so, could others in this thread that have gone through with builds like these advise on the pros and cons of the following configurations:
1. [Dual Rear USB-A to 19-pin adapter](https://www.amazon.com/gp/product/B0719J5M9V/) -> Front USB-A connection, 19-pin motherboard header -> [E-Key adapter](https://www.amazon.com/gp/product/B07WG8ZJ41) -> Front panel Type-C port
2. 19-pin motherboard header -> [E-Key adapter](https://www.amazon.com/gp/product/B07WG8ZJ41) -> Front panel Type-C port, USB 2.0 motherboard header -> [19-pin adapter](https://www.moddiy.com/products/Internal-9%252dPin-USB2.0-Female-to-19%252dPin-USB3.0-Female-Converter.html) -> Front Type-A port (I know this will work but curious about max output current).
2. 19-pin motherboard header -> front panel Type-A port, [dual rear USB-A to 19-pin](https://www.amazon.com/gp/product/B0719J5M9V/) -> [E-Key adapter](https://www.amazon.com/gp/product/B07WG8ZJ41) -> front panel Type-C port
3. Rear USB-C port -> [USB-C extender](https://www.amazon.com/gp/product/B075R7QBQD/ref=crt_ewc_img_dp_1?ie=UTF8&psc=1&smid=A3TUR5JBYCEPNE) -> Dremel out the NZXT USB-C to Type-E cable, Type-A front panel uses native motherboard connection
