[Q] ES File Explorer fails to open USB Thumb Drive topic

Hello

I have My Nexus Player unlocked & rooted. I installed ES File Explorer from the Google Play Store. ES File Explorer sees the thumb drive, and allows me to click on it with a mouse, but fails to open when I click on it and assign ES File Explorer as the default manager for it. I have tried it several times with and without assigning ES File Explorer as the default manager and it fails to open the thumb drive. I have formatted the thumb drive in FAT32 & NTFS. I have also given ES File Explorer ROOT permission. I have rebooted the NP several times with no changes. Your help is greatly appreciated!
