You can access information on removable media with or without using removable media services. For information on accessing information on removable media with GNOME's File Manager, see the GNOME desktop documentation.
After the USB device is formatted, it is usually mounted under the /media/label directory.
The device nodes are created under the /dev/rdsk directory for character devices and under the /dev/dsk directory for block devices. Device links are created when the devices are hot-plugged. For more information, see scsa2usb(7D).
If the device cannot be identified by removable media services, then try to manually mount the device. First, use the rmformat command to identify the device path and then use the mount command to manually mount the device as superuser.
If a device is mounted by removable media services then you can unmount it by using the rmumount command. If the device is manually mounted, then you would unmount it using the umount command as superuser.
