Lhasa’s tone board with RPI4 as endloint

Hi. So I’m thinking of trying a Lhasa’s tone board as the dac with my RPI4 running Ropieee. I currently have a ALLO BOSS dac hat attached to it but wanted to try something different as a dac with it. I’m assuming I connect usb out of the RPI to the USB of the toneboard to get the audio to the dac. My question is will Roon see the toneboard as the dac attached? Is there something I’m overlooking?
