xwiggen Posted May 17, 2020 Posted May 17, 2020 (edited) Armbianmonitor: http://ix.io/2miY I have this FriendlyArm ZeroPI with one micro-usb (power only) and one usb 2.0 A connection, yet dmesg yields 4x 2.0 root hubs and 4x 1.0 root hubs. Can anyone enlighten me? odd. old version is uploaded. new version; http://ix.io/2mj7 Edited May 17, 2020 by xwiggen
Werner Posted May 17, 2020 Posted May 17, 2020 armbianmonitor -u Either there are additional usb ports available via GPIO or some other components - whatever it may be - are connected internally via USB.

It's just my lack of insight on hardware level (gpio, low level boot sequence, how components connect etc) appears, never had to go deeper than simple minicom. What's an MR?
