Yes, Basically I need to access my friend's USB device over the internet, we both in different countries.
Has anyone previous experience?
I tried some google search and it's not quite helpful.
I saw plenty of USB over ethernet or LAN,
so what I'm trying to do is making LAN over the Internet with Tunngle or something like this and then using such programs
anyone familiar with better ways or tips,
I'd appreciate any help.
Simplest way to install Google Sync and add the USB drive, then he can share access with you so you can access it.

Why don't you just use remote control software and transfer files ?
