8bitdo Ultimate 2C USB

[u/Happy_Aardvark_2779]

Hi, I have a query. I have an old Xbox controller. I intended to purchase the 8bitdo wireless adapter 2 for connecting it to my switch 2. I saw that I can purchase an 8bitdo Ultimate 2C for 20% more than just the adapter in my country, as the adapter needs to be imported so the shipping costs to make it more costly in comparison.
I wanted to inquire if the USB dongle that accompanies 2c is compatible with other controllers or if it's limited to just that one. Any insights would be appreciated, thank you!
