usb device not supported

[ben_lewis1984]

Hi 

When trying to use a usb-c / headphone jack adaptor or after market usb c ear phones in my samsung s20 im just given the error message "the usb device is not supported" 

My partner has a Sony and both these accessories work fine on her phone. 

Any ideas how I can resolve this ? 

Thanks

Hey @ben_lewis1984 ,

can I ask what USB-C adapter are you using? I can see that we are offering a compatible one of our Online Shop: https://www.samsung.com/uk/mobile-accessories/type-c-adapter-ee-uc10-ee-uc10juwegww/
