If you are running SimpleUSB now, switching to USBradio will likely make the situation worse as there is generally more DSP going on in USBradio than SimpleUSB - depending on exact configuration.
Raspberry Pi’s are inexpensive as compared to some PC’s which could have enough horsepower to properly operate 3 or 4 radio interfaces, even in full DSP. If you really want to run multiple radio adapters on a single appliance, consider choosing a hardware platform powerful enough to do it properly.

Someone else individually replied to me and said it’s likely an issue with SimpleUSB and I should try using usbradio instead. I will be trying that tomorrow, but still open to other suggestions.
You have USB2 ports on a USB2 hub. There is only so much data you can push across that bridge. RasPi weak link is the USB2. I am not going to rewrite all the work done by the many masses.
I have a similar arrangement, however I use a RasPi for each radio, a small Netgear SW and put in linking shortcuts.
This method ALWAYS works… It does not add that much cost or footprint.
