HDD plugged into supersede 7 hub not recognized after updating to El Capitan OS X

Since updating to El Capitan, HDDs plugged into my hub don’t show up on the desktop or in finder. If I plug them directly into the macbook’s usb ports, they work just fine. Does the Plugable hub have a driver that can be updated or is this a problem with El Capitan?

Sorry to hear about this issue.

I’m going to contact you directly via email to request some diagnostic information to try and find out why this is happening.
