Is this device getting its IP address from a DHCP server in both cases? 
Or is it being set up manually?  If manual, there might be routing 
stupidity going on, or the device might think that its actual ethernet 
port still has an address in 192.168.1.0/24 .  If that happens, it'll 
probably try send packets for 192.168.1.146 through the ethernet port 
instead of the USB port, which would cause the symptoms you described.  
What's "route -n" say?  Can you ping 192.168.1.146 through your actual 
computer?

I thought that ethN was deprecated, and that everyone was supposed to 
use the new alphabet soup names like enp4s0 (PCI bus 4, slot 0) since 
the old numerically-named devices can change at random depending on the 
order the kernel developers decide to do things.
