USB switch with DAC

[nosferatu_cat]

I have a Schitt Modi 3 that has one USB input.  I'd like to use it with a Raspberry Pi (with Moode) and my tablet.  Cable swapping is inconvenient because it's hard to get to the back of the DAC.  Would a USB switch, not a hub, work?  I tried a KVM I've had lying around for a long time and was only able to get the tablet to work.  Are there better options?  I asked Schitt and was told that they'd never tried it but that it would probably be safe. 

Anyone with experience with more than one audio source connected to a single USB port?
