Hey everyone! 
I’m using a custom Nerves system based on Raspberry Pi 4. Some time ago, I added extra drivers to support several USB-to-Ethernet adapters (AX88179_178A, AX8817X, and ASIX).
It used to work fine — here’s a snippet from dmesg when it was working (full dmesg added on the thread):
usb 2-2: New USB device found, idVendor=0b95, idProduct=1790
usb 2-2: Product: AX88179A
usb 2-2: Manufacturer: ASIX
ax88179_178a 2-2:1.0 eth0: register 'ax88179_178a' at usb-0000:01:00.0-2, ASIX AX88179 USB 3.0 Gigabit Ethernet, ...
However, after updating to Nerves 1.31.x (Not sure if other previous releases have the same issue), the RPi4 no longer loads the correct drivers when detecting the USB adapters.
Now dmesg only shows (full dmesg added on the thread):
[ 0.875175] erlinit: Unable to create seed directory
[ 0.964188] hub 1-1:1.0: USB hub found

[ 1.427106] usb 1-1.4: Manufacturer: ASIX
[ 1.427110] usb 1-1.4: SerialNumber: 003FF336
…and no ethX interface is created.
The modules asix and ax88179_178a are both built into the system and but no longer loaded at boot.
I’ve tried using modprobe, new_id, and manual binding (echo "1-1.4:2.0" > /sys/bus/usb/drivers/asix/bind), but I always get:
sh: write error: No such device
It looks like the device reports itself as AX88772E and AX88179A but with the VID/PID (0b95:1790) usually associated with AX88179A and ASIX — so neither driver recognizes it.
Has anyone run into this issue before?
Or know if I need to patch the driver to add support for this specific combination?
Any ideas or pointers would be really appreciated
