blacklist xhci_hcd
For testing/investigation, I would blacklist xhci_hcd , and load ohci_hcd ehci_hcd in /etc/initramfs-tools/modules.
update-initramfs -u
lsinitramfs /initrd.img | grep "etc/modprobe.d/"
cat /etc/modprobe.d/blacklist.conf
lsinitramfs /initrd.img | grep "etc/modprobe.d/"

george@Debian:~$ cat /etc/modprobe.d/blacklist.conf
