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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1928710 Title: ubuntu server 20.04 LTS for ARM64 on Raspberry Pi4 could not handle more than 32 USB3 devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1928710/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
