Review on UGREEN Extension Extender Compatible Thunderbolt by Griselda Monclova

Description says it fits a USB-C hub but doesn't mention if that hub has multiple USB-A ports (most have) , You cannot use USB 2 devices if the hub goes to the computer through this extension. Unfortunately, my USB-C hub also has an SD card reader that needs to be plugged in internally as a USB-2 device, as my SD cards are also inaccessible unless I plug the hub directly into it. But I suspect their sales would suffer if they listed everything their product can't do.
