No need to reinstall - that’s absolutely the last resort.
If you are using legacy boot, then you can interrupt boot, and edit
boot parameters to restore the USB controllers to dom0.
Dont know what the equivalent would be for UEFI, if there is one.
Otherwise, boot from installer, get shell and edit the parameters there.
If necessary hobble sys-usb to avoid it starting and stealing the usb
devices until you are ready.
This has been covered on the mailing list a number of times - search the
archives.
If you need more help, post whether you are UEFI or legacy boot, and
what level of Linux knowledge you have.
