MAX doesn't find my USB-Scope

[Jick]

Cheers!

I am using Agilent DSO1014A USB-scope. If I switch my scope first on and then launch MAX it doesn't see my scope. Refresh doesn't help. Why?

Only way which helps is to launch MAX first then power on scope. That is when NI Signal Express lauches too. I would like to see my scope like other non-USB devices on the Devices and Interfaces list of MAX without restaring scope after MAX launch.

BR,

I think I read somewhere that it is because USB devices only init once on plug-in, and not after that - something to that effect.  Therefore, you need to plug it in AFTER you start MAX, or max won't see it.  That's probably not exactly right, but I think it is close.

You really should power up- power down the scope with USB disconnected if it is not USB Powered (Another Plug'n'Pray feature)

(Assuming Windows)

Unplug the scope

Right click NI Device monitor in the systray

Select "Clear all device associations"

plug in the scope

Click the balloon while the device driver is installing to pop up the association wizzard

select "Do nothing" and select the "Allways do this" checkbox

Breathe sigh of relief
