I'm trying to use Linkit 7688 devboard to teach stuff in class, but the board does not come with an RJ45 port and by default it should be accessed via Wi-Fi. It will be quite a signal and network mess to make every student's board act as AP or connect to Wi-Fi routers, so I thought maybe reverse usb tethering could do the trick.
I've been searching for infos about reverse usb tethering for OpenWRT for a while but unfortunately there aren't really much information out there, except this short document: https://openwrt.org/docs/guide-user/network/wan/smartphone.usb.reverse.tethering
However this doc isn't helpful too as I'm not trying to tether network to an Android device, but a PC. I've also gave it a try and proved it didn't work
Does anyone know if reverse usb tethering to PC is actually doable or I should seek other solutions?
Thanks a bunch!
Appreciate your reply!
I tried to look for kmod-usb-gadget-eth in kernel driver menuconfig options, however I couldn't find one.
I've set the target profile to MediaTek LinkIt Smart 7688. If I can't find kmod-usb-gadget-eth in build options, does it mean the chipset doesn't support it?
About the dependency, I'm not sure I understand it correctly, but it seems TARGET_PER_DEVICE_ROOTFS is target dependent. Is it possible to change what's defined in a target profile? Also I'm not sure what the m in the middle is supposed to mean....
I'm sorry if this is a noob question, but it really puzzled me even after some extensive googling
Thanks to all your replies
Yes, I finally realized that USB host and OTG are different down to the hardware level after tons of searching.
It is "physically" impossible to ask a USB host to do OTG things so I'll have to go for adding RJ45 hat for 7688 board.
but why not use them in WiFi station mode?
Appreciate the advice , but I try to keep things as clean as possible to avoid wasting time on possible network issues if they all connect to an AP.
So the I guess the best scenario would be having p2p connection for every student and their board.
