2.7 Re-enabling a disconnected PS/2 mouse (AV4USB-PC only)
If you disconnect the PS/2-style mouse from the AdderView by accident during
operation then the mouse operation will be lost when the mouse is plugged back in.
To avoid having to reboot the entire system in this situation the AdderView is fitted
with an automatic mouse recovery system.
With the PS/2 mouse disconnected, change the channel using the front panel key or
keyboard hotkeys. The AdderView detects that the mouse has been disconnected
and triggers the automatic recovery system. Plug in the PS/2 mouse and the
AdderView will re-initialise it.
