Oh, and if you are specifically looking for one of the very popular edge Drivers from commmunity developer Mariano Colmenarejo , which mostly end in his initials MC, here’s the invitation link for his channel. (For some reason, a lot of people recommend one of these without including the link. 
)

But I do recommend using the links in the previous post to try to find his author thread on the specific device you are looking for, because that thread will often include important information about configuring the driver. Also, that thread is where you would ask any questions about it.
