First time using usb/ether, so let me share my experience for other users.

This is on the last 9pi image at 9legacy.

First, I added a line with did=0x8153 to /sys/src/cmd/usb/usbd/usbdb.
Browsing the list's archives I thought that ether1=type=usb should be
added to the configuration file (cmdline.txt on the pi), but etherusb
wasn't in the link section of the pi4 kernel configuration file, so #l1
wasn't created. I added, compiled the kernel and then a dummy #l1 was
created, impossible to configure. I could use manually usb/ether and
configure the device mounted in /net, but usbd didn't detect the usb
card. Then I removed the ether parameters in cmdline.txt and etherusb
from pi4 to be sure, now usbd recognize the card and creates the
device /dev/etherU0. Other programs expect the devices mounted in
/net. I'm binding the device inside a directory in /tmp and then
binding this directory to /net. I would appreciate if someone shares
the correct way of doing this.

In summary, the sequence was:
ether1=type=usb in plan9.ini (cmdline.txt)
etherusb in kernel config
#l1 is created but useless
usbd doesn't work because etherusb
usb/ether works and the device appears on /net/
remove ether1=type=usb and etherusb from the kernel
now usbd works but the device doesn't appear on /net but on /dev

I finally made it work, but this is a mess, really.
