So I'm aware of Ugreen ones working fine, wondering if anyone has USB2.0 100mbps version? Since those need to be ordered from other countries I'm also wondering any other working examples, at worst I'll buy from either amazon whichever I find to be closest and delivering to my country, TP-Link is really well represented here, so is DLlink, I tried looking for Asix chipsets found that a lot of manufacturers don't specify which one is used? Any info would actually be helpful
those interface drivers are included in oreo kernel for mibox:

I believe that you will find compatible usb ethernet without problem with help from this list.
I'm using a local brand with a realtek chipset which is usb 2.0 and 100mbps version with 3 port usb. Works fine.
I used some old AF Trendnet 100 Mbps ones some time back and they worked. I don't have the model and they're likely discontinued but if those work most should I think.
here's a funny thing: https://www.tp-link.com/uk/products/details/cat-5688_UE200.html
you can actually see Mi Box on a pic of supported devices
my unitek https://www.amazon.com/gp/product/B01MZBFC9K/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 worked great pre-oreo. stopped working the second i got updated. tested working on pc so the product still works. just something changed from MM to oreo in the mibox code/drivers.
I'm using this one. Works perfectly. https://www.amazon.com/dp/B00LLUEJFU/ref=cm_sw_em_r_mt_awdo_fdhJCb31M7ZV4
I got a tp link gigabit ethernet adapter for about 20$ and it works great on both my mibox 3 and mi box s
