It's not VT dependant - I tried to post the solution but don't see it here,
may be got too long

for this you have to use the 'users' mount option or put it in the fstab for
the particular device

I suggested to use device by uuid

/dev/disk/by-uuid/3fca395b-d75d-44ab-98be-9ec05b2e45fd /media/usb_2G_part3
auto users,noauto,atime,rw,nodev,noexec,nosuid 0 0

and it works for every user
