Recently I had some USB enumeration loop (turned out to be the Index umbilical connector) that made me disconnect everything one by one. What a marathon. The USB hub dedicated to wireless dongles alone has a wireless keyboard/touchpad adaptor, the one of the Steam Controller and an ANT+ stick. Elsewhere the homebrew stick/rudder is linked up, the Nrf52 devkit, keyboard, mouse, another touchpad, the hub where I connect Android devices for development and occasionally a Garmin for some cIQ stuff. A modified webcam I used to use for infrared headtracking and that cheap portable usb audio with built in phantom power for a condenser mic headset (the firewire audio interface seems to be acting up). The old laser printer is permanently connected whereas the scanner is only plugged in on demand. Currently disconnected are the throttle quadrant, the trim box (with yet another touchpad, still ps/2) and the midi controller. Somewhere there's an arduino configured as an nrf52 programmer. Yes, I need a notebook computer free of most of that stuff to get actual work done.
