Describe the bug Raspberry Pi 4 4GB does not boot in MANU mode when plugged in using ethernet and DHCP does not give assign an IP address to its ethernet interface.

To Reproduce Steps to reproduce the behavior:

1. Use regular install instructions for Pi0w
2. Plug ethernet cable into computer and Pi 4 4GB
3. Wait for boot

Expected behavior Should boot in MANU mode when ethernet is detected and DHCP to provide an IP address for the interface.

Environment (please complete the following information):

• Pwnagotchi version: 1.5.5
• Debian 10
• Raspberry PI 4 4GB

I see similar behaviour with version 1.5.6-beta2 (1.5.5 won't boot at all for me) on a Pi0w. I connect the Pwnagotchi to my PC's USB port, on the RPi's data port, and the device boots into AUTO mode, eventually switching to AI mode.

It looks like the way it detects if it should boot into AUTO/MANU mode is based on if usb0 (for Pi0W) or eth0 (for everything else) is up when pwnagotchi launches:

If you manage to log into your devices while they're in AUTO mode, can you run the following command and post the output?

for device in usb0 eth0; do echo "=== $device ==="; cat /sys/class/net/$device/operstate; echo; done
