Armbianmonitor:

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;

armbianmonitor -u

 

Either there are additional usb ports available via GPIO or some other components - whatever it may be - are connected internally via USB.

Why all are enabled? Simply because there is nothing wrong if they are (on this particular board) and it would require either a test or seeing documentation to be able to know which to enable. Even this is almost nothing is one of those from the mountain of mini cosmetic tasks.

Yeah I understand indolence, I did a check on http://wiki.friendlyarm.com/wiki/images/7/71/ZeroPi_20190731_Schematic.pdf yesterday to find how everything is connected.

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?

Just curious, I'm used to eth nics being handled by a single kmod, but there's something funky happening between sun8i-dmac and realtek?
