Digital usb different sources

Please be kind as I am new to this and have looked on the net for months. I bought a W4S DAC-2 made in 2012. I’ve tried contacting them but not the best support on vintage products. I have a old ( about 6 years) Dell laptop that I can connect to the DAC via usb and get sound out without issue but my note 9 and my BLU G8 i cant. When i connect the phones I get messages that they are connected to the dac on the phones but when i go to play music i get no dac connected. This is probably because the Laptop usb is a different type than the phones?
