Yep(filesystem was „attacked“ by tests),
 after „renewing“ the (msdos-)root-filesystem(incl.. U-boot.bin) on the uSD , `got the keyboard/mouse back to responding state (keyboard/mouse-response on HDMI while no simultaneously access to UART-console-keyboard-input(using picocom)…
And (!) detaching and then reattaching  the keyboard/mouse suddenly gives simultaneously access on picocom and HDMI-console) , last test for today: third trial ofunplug/replug keyboard/mouse worked so this was a good test, which let me assume that after some fixes Robert`s pcie-driver will be ready for review on phabricator...
