Comment 10 for bug 1928710

I understand there is no way around the 32 device limit on the VL805 using USB3. But I'm nowhere near 32 devices, yet. On the Pi4 I don't even have a keyboard plugged in. It has one 16port USB3 hub, and I'm only able to plug in 6 hard drives on it when the hub is on a USB3 port, or 12 hard drives on it when the hub is on a USB2 port. But dmesg shows that even on a USB2 port, xHCI is used, not eHCI.

Also, I was able to disable xHCI driver during loading by blacklisting it in cmdlines.txt, but then eHCI is not loaded in its place, so in that case I don't have usb capabilities at all. lsusb returns nothing for example. I'm trying to figure out how to load that manually first.
