Need help with USB powered DAC

[Lttlwing16]

I have the Drop+Grace Design SDAC which is powered via USB. My issue is I'd like to have two USB inputs to the SDAC but have the device powered independently of either of these two inputs. Is this possible? If I use a powered USB hub and went directly into the SDAC with the main leg of the hub, would it still power the SDAC, or would the 'powered' part of the hub just power the devices attached (In this case the two pc's, which don't need power input, but would have power output themselves).
Thanks!

You may need a switch, not a hub.

What's the best way to share one USB DAC between two PCs?

I have a RME ADI-2 Pro that I want to share between a PC and a Laptop that are both at my desk. I don't need audio from both at the same time, and in fact was thinking I could just purchase a cheap USB "switch" like this this and the appropriate cables. There are a surprising number of reviews...

Right after I typed this post, I got thinking about it and in fact I need both. I already had the two PC's connected to a powered KVM switch for shared monitor, keyboard and mouse. It dawned on me I just need a usb hub to one of the usb ports on the KVM switch for Keyboard/Mouse, and the other port to the SDAC.

So far problem seems solved. However, not sure what kind of output the KVM switch has to the SDAC. I believe I read the SDAC pulls 130mA over USB.
