> How to install driver for NI USB-SH ,GPIB to USB instrument in FEDORA 19.and

 

You will need to read the documentation for the NI USB-HS to determine how to use it under Linux.  Although the USB-HS says it supports Linux, I could not find any information on installing it under Linux on this page:

You may be able to use the VXI-11 driver if they make a Linux device that looks like VXI-11, but if not you might need to write an asyn port driver.

That is not what VDCT does.  You need a driver (preferably based on asyn) that records can then talk to using StreamDevice or other modules.
