Output shows live USB mounted on /dev/sdb1. Did you manually set that as the mount point because normally when you plug in a USB stick it will be mounted under /media/username?
Anyway, you can't write to a live USB if that is the problem. However, you said you could not write to any FAT32 formatted USBs. Are you (for some reason) manually directing them to mount to /mnt/sdb1? If so, then the mount point is probably owned by root. Unmount and eject the live USB and put in a different problem USB. If your system doesn't auto-mount it on insertion, find it in file manager and click on it to mount it. Look in address bar of file manager to see where it's mounted -- should be /media/username/usb-stick. Now try copying something to it. It should work. If for some reason it's getting auto-mounted to /mnt/sdb1, open a terminal and run this command to see ownership info for the mount point:
If it's root, change it with this command:
