I see. Well at least you basically had plenty. I wish you luck, I don't believe if they were functional in other OS, that any bios modifications should be necessary. Though Windows has a reputation (probably deserved) of drivers that work around iffy hardware. Another possible solution would be a USB hub device, they're cheap and I bought one for my server. I'd attach the slow devices to it and put the drive on another port if you did that.

    dbarron I do use a hub for KB, cam, thumb drives. and the like. I have a minimum of 3 devices that want dedicated ports to work well/at all, and have only 3 ports to play with now, so I have to plug/unplug my external drive and game controller receiver whenever I want to use them

      during install of Soulus my KB and mouse "disappeared " as they were in legacy ports, so to even complete install I had to unplug all other USB devices and find the USB ports that were still "active", those being the 3 usb 3 flavored ones that continue to work. No change I have tried in BIOS so far has enabled the rest of them.

      Is your power supply capable of providing enough current for all the devices? In other words, does the situation get worse if you plug in more peripherals?

          Hmmm, does not sound like a Solus issue, as these stuff are either hardware related (which concerns the Linux kernel as that handles the hardware) or BIOS related. We would know for sure if you could use a live CD/USB to test it under another distribution. That is a fairly mature motherboard so I assume the latest kernel update would not fix it either... Unfortunate part is, it is difficult to suggest anything BIOS related without having access to a motherboard that has the same BIOS. I am stumped, sorry 🙁

            arkhenius did the live distro and had same issue, this is BIOS related for sure. I have latest BIOS and kernel installed

              to update, I have tried live cd of Manjaro, Tails, Kali, Solus all with same issue. Legacy usb ports pass .5v, BUT no data/ OS recognition

              You might try to find a legacy install of Ubuntu (like maybe two years back?)...but I suspect you'll find the issue persistent there too. This just to make sure that it isn't an issue with most recent kernels.

                [deleted] Kali, Solus, Manjaro and TAILS all have same issue when loaded as live OS . USB legacy ports all pass .5v but no data/OS recognition.

                  dbarron Thanks, next I am going to boot into BIOS and pop pix of my USB/inputs settings to post. Suspect it is in legacy support/handoff settings

                    If I recall, changing the IOMMU controller to enabled in this configuration renders ALL USB ports useless and I must reboot with PS2 KB or mouse, so that's one I don't want to change again

                    That seems to be a common issue with that series of boards on Linux.

                    Add iommu=soft to boot parameters via this line (run it in a terminal)
                    echo 'iommu=soft' | sudo tee /etc/kernel/cmdline

                    Then run
                    sudo clr-boot-manager update

                      [deleted] THANK YOU SO MUCH!!!! I will reboot and see whats up, and get back at you!

                        [deleted] before I reboot, when I do should I hit5 up the BIOS and enable IOMMU? I'm guessing yes, but confirm, I don't feel like having to run and get my ps2 keyboard and mouse out again 🙂

                            Drewfus It doesn't hurt to try first without

                              Just did, and I'm GOLDEN, all USB ports working as they should! Thanks a million!
                              SOLVED!!!!
                              I tried a dozen other Linux boards, and even Gigabyte themselves, and you got me sorted, I really appreciate it!
