content: If there is a datasheet that goes with the connector, you should be able to easily make a footprint.

content: The problem with what you are asking is that the vendors (like aliexpress vendors) do not have a consistent supply of parts so the USB connector [or any other part, for that matter] you buy from a given vendor may not be the same that someone else buys from that vendor. For what it's worth, you can find parts on eBay/Amazon/Aliwhatever that do have datasheets. I found a strip of 50 USB connectors on eBay years ago for a few dollars - there was a datasheet so I was able to make a footprint and it has worked just fine.The second problem is that making up a footprint for a part like that without a datasheet is going to be hit or miss, probably taking some trial and error experimentation. I assume that is why you said "proven". But that seems a lot of effort to save a little money. As they say "penny wise,..."Personally, I would not bother. USB connectors are not that expensive to begin with and you can get Aliexpress level prices from Chinese distributors - LCSC for example. It will have a datasheet. And they take PayPal. Shipping will probably more than double the cost to you but still pretty low. For example, at LCSC,C145792is a micro-B connector for $0.114 USD each. Falls to $0.0853 USD in quantity 50.For what it's worth, western distis have microUSB connectors for around $0.50 USD if you don't want to bother with Chinese distis.

Cheaper connector from XKBhttps://lcsc.com/product-detail/USB-Connectors_XKB-Connectivity-U254-051T-4BH23-S2S_C482361.htmlis trash though.
