NOTICE: This product allows the data transmission between both the connected computer with both cards (CFexpress Type B Card and SD 4.0 UHS-II Card) simultaneously. However, some connecting port(s) may not be able to supply enough power (especially a USB-A connecting port) to allow the reading from both cards via the card reader simultaneously. When power being supplied is insufficient for two cards being read at the same time, an error message of "Device not recognized" would pop up. Simply removing one of the cards from the card reader and it will perform normally again. Or connect it to a USB-C connecting port, which would be able to supply enough power for the reading of both cards simultaneously.

A: When you are facing “non-auto-assigning Drive Letter” issue using external card readers & USB Flash Drives, perform the below to solve the issue.
 
Making sure that the Virtual Disk service is running. You can check the status of this service in the services management console (services.msc).

Go to <Computer Management>
Click on <Services> Tab

Making sure the “Service Status” shows “Running” & all START, PAUSE & RESUME buttons are dimmed. If “Service Status” showing as “Stopped”, CLICK ON THE “START” button.
