If so, here's a nice and simple project idea: that board with two USB connectors and connect it to the two ends of the same cable; you send a pseudorandom bitstream down one end and verify if it comes out correctly at the other end and report the bit error rate (USB cable tester)
looks like it only has the physical connections for USB 2. Fun fact about usb 3, it’s really a completely separate physical standard from usb 2, just designed in such a way that a single port can have BOTH usb 2.0 and 3.0 connectors in it at the same time. In theory this would allow for devices to use the full bandwidth of 3.0 + the full bandwidth of 2.0, but as far as I know no device does that.
But is it fast enough to do USB 3?

Apparently there is a newer Qomu device that combines the FPGA and an MCU: https://www.crowdsupply.com/quicklogic/qomu
Its a cool board! Second submission on it ~7 years ago got a tiny bit of traction. https://news.ycombinator.com/item?id=19488397
There's a fun/interesting lesson on some creative routing for the ice40 FPGA FPGA here. Which I re-stumbled into just last week by happenstance. https://danielmangum.com/posts/spi-routing-ice40-fpga/
One of the makers Tim @mithro Ansell is pretty great. A bit quieter on the social media these days, but https://bsky.app/profile/mith.ro
