How to have correct permissions for files 664 and dirs 775 from usb disks?

Type:

sudo mount -t vfat -o rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,fmask=0113,dmask=0002,utf8=1,showexec,flush,uhelper=udisks2 /dev/sdb1 /media/usb


Or put to /etc/fstab:

UUID=1234-5678 /media/usb vfat rw,nosuid,nodev,uid=1000,gid=1000,shortname=mixed,fmask=0113,dmask=0002,utf8=1,showexec,flush,uhelper=udisks2 0 0
