Review on Unitek SD Card Reader USB C, 3-in-1 Type C to USB Camera SD/Micro SD Memory Card Reader Adapter with 2TB Capacity for MacBook Pro/Air, iPad Pro, XPS, Samsung Galaxy S10/S9/S8 and More USB-C Devices - 15cm by Quintin Boner

Below is my first review. Technical support from Unitek staff was prompt and very good. I ended up "solving" my problem by installing USB message monitoring software. Everything behaves on the test bench. This solves the problem for the time being. The actual problem should be diagnosed with a hardware analyzer and is probably driver (operating system) related. ====== I also expected to be able to write data through this interface.
