(SOLVED) How to enable smb2 / smb3 (1 reply)

I'd like to try SMB2 / SMB3 between pogoplug and windows 8.1 but so far I can't get it to work. Windows 8.1 reports connection as SMB1. Here is my smb.conf. Should I add security to enable SMB3?

[global]
        client min protocol = SMB2
        client max protocol = SMB3
	log level = 0
	log file = /tmp/%m.log
	guest account = root
	load printers = no
	socket options = IPTOS_LOWDELAY TCP_NODELAY SO_KEEPALIVE
	wins server = 192.168.1.1
	map to guest = Bad User
	netbios name = POGOPLUG
	write cache size = 2097152
	server string = POGOPLUG
	printing = bsd
	workgroup = WORKGROUP
	os level = 20
	use sendfile = yes
	printcap name = /dev/null
	security = user
	disable spoolss = yes

 #unprotected/public share without login
 
[root]
  path = /
  read only = no
  public = yes
  writable = yes

[usb]
  path = /mnt/usb
  read only = no
  public = yes
  writable = yes
