realtek 8153 usb ethernet adaptor works - interface was named eth0.

The default system runs dhcpcd 6.6 with an allow list for wlan0.
I was able to get an address for eth0 by running: dhcpcd -n eth0

But this clobbered the already running dhcpcd instance. Allowing the device to sleep seems to kill my running dhcpcd and restoring the old one, but this still leaves the IPs on both interfaces (which is weird but i'm not complaining).

There is a running dhcpd-dbus - so hopefully there is a better way to do this.

Also on the usb port I tried to connect a usb audio adaptor. aplay is installed and lists the device

[root@kobo onboard]# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Device [C-Media USB Audio Device], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

There are no default sound configs in the system, so playing a wav failed (probably missing channel alsa settings). But I was able to feed some random noise to the audio output. I did not check the mic.

Finally I tried to plug a couple USB hubs to add more devices. But results were mixed. First I saw some dmesg errors with devices failing to get address, but eventually was able to connect the ethernet adaptor and the audio card via a cheap 4-port USB hub.
