Issac,
If you have been able to complete the Buster install and install GRUB on
the appropriate disk, please try the following:
__DISABLE__ IOMMU support in the motherboard BIOS.
Reboot to the GRUB menu and type "e" to edit the default boot
option
type " iommu=soft" (no quotes) at the end of the "linux" line.
Press the "F10" key to boot the default option.
If that works (the system comes up to a Debian login screen) then you
need to edit /etc/default/grub (under the root user; create a backup
copy first) and update the line below with:
GRUB_CMDLINE_LINUX="iommu=soft"
Save the updated file
Run the "update-grub" command (again, under the root user).
Reboot
I have two systems with Gigabyte motherboards and I need to add this to
the GRUB configuration in order to get all USB ports working properly.
