I created several users but I find that after mounting a FAT32 USB stick, only user "PI" can access it. drwx------ 3 pi pi 4096 Jan 1 1970 1 No matter what I try, I can't seem to change the owner, group or access permissions to anything other than PI. mount -t vfat -o uid=joe,gid=joe,umask=000 /dev/...
