Hi! I was able to connect my Kindle 4 to my Mac over usbnetwork with the provided instructions (using host IP 192.168.15.201 and kindle IP 192.168.15.244) pretty easily, but when I attempt to do the same thing on my Raspberry Pi Zero on Linux, I'm running into "No route to host" while attempting to ssh.

This is the full output when I run relevant commands:

pi@raspberrypi:~ $ sudo ifconfig usb0 192.168.15.201

Originally I had an issue where usb0 did not show up in ifconfig at all. It appears I solved the issue by editing config.txt and cmdline.txt as detailed in this Adafruit article.

I found a much earlier thread in MobileRead's forums that seems to cover a very similar problem: https://www.mobileread.com/forums/sh...d.php?t=222133
I used it as a reference while troubleshooting. However, I don't have network-manager installed, and my "ip route show" output looks a little different:

default via 10.0.1.1 dev wlan0 proto dhcp src 10.0.1.208 metric 304 
10.0.1.0/24 dev wlan0 proto dhcp scope link src 10.0.1.208 metric 304 
169.254.0.0/16 dev usb1 scope link src 169.254.96.198 metric 205 
192.168.15.0/24 dev usb0 proto kernel scope link src 192.168.15.201 linkdown

I think the difference that stands out the most is the "linkdown" at the end of the final line, but I'm not sure. Also, there is both a usb0 and a usb1 even though the Pi Zero only has one usb port. I'm not too sure why.

How should I proceed with the problem?
