The linkage from the keyboard and mouse is wireless since mouse and keyboard cables only serve to get tangle in multihorsepoer spinning machinery, utilizing the usual dime sized dongles plugged into a usb-3 4 port hub, plugged into a usb-2 port on the rpi4. The 2 usb-3 ports are occupied by a pair of SSD's plugged into usb-3 to sata adapters. The radio is turned off, and stays off. cat-6 from the local net is plugged in. 100% local addresses, NAT'd to the internet for everything via dd-wrt. How else can one put a keyboard and mouse on an r-pi except via a usb port? Thanks. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
