how come Illustrator does not recognize my tablet while Photoshop yes?
Complain to Huion about their driver.
As long as they don't improve it, you can try and install a Wacom driver on top.
This usually tricks Illustrator into working with your tablet.
Note: it's a hack. It worked for most people, but may or may not work for you.
Please report if it works for you. Thank you.
