USB Not Working

[NicWow]

Qubes OS version:

This picture should explain itself:

But basically, I need to add some files to USB and it just won't connect. Can some plz help me?
Thanks in advance!

Edit: Screenshot doesn't seem to work either but basically I attached the USB to my AppVM "Firefox" and if i open folders in other locations it doesn't appear.The AppVM's template is Fedora26.

Edit2: I also made a reddit thread because I coudn't figure out how to download apps and have some error messages you can view them here: https://www.reddit.com/r/Qubes/comments/8nf2t6/how_to_download_3rd_part_apps/ and here https://www.reddit.com/r/Qubes/comments/8noffo/how_to_delete_apps_and_files_in_qubes_os/

UPDATE
I think I got it working. When I plug in the USB 2 instances show up one appears as "sys-net:sda - USB_2.0_FD ()" the other one is "sys-net:sda1 - USB_2.0_FD (MY-USB)" "MY-USB" was what I named the USB and was the one I attached. The other one removes when I attached one to a Qube. "sys-net:sda - USB_2.0_FD ()" shows up in "other locations" as My-USB while the other one doesn't work.
Although I believe this is solved this is still a bit of an issue as it is very hard for the user to figure out how to add USBs.
