    I have a HP proliant DL380 gen 9 which was working just fine, but after a reboot both the USB keyboard and mouse are no longer detected after the legacy BIOS startup.

    I tried to use them directly connected to the server, and to go through the iLO card, but it does not respond.

    To me, I have to proceed to a factory reset, but maybe there is another way ?

      Yes I am using a KVM, it worked fine until now, I will remove it from the equation.

      Which USB slots are in use? Sometimes front/back can make a difference, though normally only when flashing BIOS.

    Once the KVM gone, the keyboard worked. Thx !
