Just to follow up for future readers, I worked this through a bit with zmatt on IRC, it was both issues.
A new PocketBeagle with USB1 on a breadboard would connect low-speed USB devices, but not high-speed USB devices. A new PocketBeagle with USB1 wired pretty directly would connect both. The old PB still wouldn't connect even with the direct USB1 wiring, so it's likely I fried the USB1 components on that board. Thanks!
