simpleusb.conf: Behavior with no device

[tsawyer]

Not sure if this is a problem/bug or not but warrants a mention. When testing the new simpleusb-tune-menu with no device connected:

• The V) menu showed nothing, returning to the main menu.
• The 1) menu showed Active Simple USB Radio device is [node#].
• Did not test other menu items.

simpleusb.conf settings are:

[general]
;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
; jbenable = yes              ; Enables the use of a jitterbuffer on the receiving side of an
; simpleusb channel. Defaults to "no". An enabled jitterbuffer will
; be used only if the sending side can create and the receiving
; side can not accept jitter. The simpleusb channel can't accept jitter,
; thus an enabled jitterbuffer on the receive simpleusb side will always
; be used if the sending side can create jitter.

; jbmaxsize = 200             ; Max length of the jitterbuffer in milliseconds.

; jbresyncthreshold = 1000    ; Jump in the frame timestamps over which the jitterbuffer is
; resynchronized. Useful to improve the quality of the voice, with
; big jumps in/broken timestamps, usualy sent from exotic devices
; and programs. Defaults to 1000.

; jbimpl = fixed              ; Jitterbuffer implementation, used on the receiving side of an simpleusb
; channel. Two implementations are currenlty available - "fixed"
; (with size always equals to jbmax-size) and "adaptive" (with
; variable size, actually the new jb of IAX2). Defaults to fixed.

; jblog = no                  ; Enables jitterbuffer frame logging. Defaults to "no".
