change from raw to instr USB device

[ku_ku]

I am confused. In the wery beining my R&S NRP-Z91 sensor apeard as instr device and could comunicate with it using these drivers: http://www2.rohde-schwarz.com/en/service_and_support/Downloads/Drivers?type=25&downid=1255

New sensor apears as raw device and LabView 8.5 gives error device not connected. But  sensor is recognised visa interactive controll and MAX.

I alredy deleted files in windows\inf folder, what elese to do?

You deleted files from Windows/Inf which is the location where device drivers get stored for detection when you plug a device in.

You plug a device in and wonder why it doesn't show up or the program can't access it.

Why did you delete the files?

Did you try reinstalling the device drivers?

I deleted because I wanted to change from ::raw to ::instr of course I reinstaled drivers (few times) but it's again ::raw

What to do?

Hi Ku ku,

Have you reassociated the drivers with the device?   Did you create a driver using the driver development wizard?  You can see what driver the device is using in Device Manager.  There you can select Update Driver and update it to use the driver you would like it to use.

Can a VISA Instr be hooked up to a VISA usb raw?  Here is my situation.  I want to make an abstract spectrometer class.  I have two implimentations of this class, both are Ocean Optice spectrometers.  Once driver set has all the VISA terminals set to usb raw, the other spectrometer's driver has all the VISA terminals as the instr class.  I can not seem to make 1 abstract spectrometer class with a generic VISA resource that will work for both implimentations unless there is a way to change a VISA instr to a VISA usb raw.  Can it be done?  Any suggestions?

Oops.  Looks like I answered my own question.  I kept trying to treat the VISA resource like a class and use the "to more specific" or "to more generic" functions to up or down cast the VISA resources.  This did not work.  A simple type cast does seem to work however.
