So I want to tuck my control box under the table my CR10 v2 is on, so I want to extend my sd card out at the edge of the table. I got an SD extension (full size to full size since the v2 uses a full size card). It works fine until I remove the card and put it back in. It wont read the SD card unless I remove the other end from the box and remount it in the box. I noticed theres no UNMOUNT/MOUNT (or Refresh) in the SD card there a work around so I dont have to do that (as it makes extending the sd card pointless since I have to remount at the box anyway)
