When using Solvo we recommend always using the included USB 3.0 cable that comes in the box for optimal performance.
The USB port in the Solvo is a USB-B type 3.0 which supports bandwidths up to 5000 Mbps and can pass video (up to WQHD (2560x1440)) (4K @60Hz available september 2020), bi-directional audio, Gigabit LAN and USB communication simultaneously through a single USB 3.0 rated cable.
You can however also use other certified USB 3.0 cables or even a USB 2.0 cable. You can see the difference between a USB 3.0 and a 2.0 cable here.
However be aware that due to signaling rate limitations you cannot pass gigabit LAN while using video, audio and USB in a USB 2.0 rated cable. A USB 2.0 cable is only rated for a signaling rate of maximum 480 Mbps vs 5000 Mbps for a 3.0 cable.
Also be aware that some older laptops will still have USB 2.0 ports only or a combination of both 2.0 and 3.0 ports which are normally black for 2.0, blue for 3.0 and red for 3.1.
So plug the Solvo into the fastest available USB port for best results.
