Encountered in some computers while in use: ErrorRsrcNfound: Insufficient location information or the device or resource is not present in the system

[zengyuhan503]

hi I am now experiencing an error that says I did not find the relevant resource, This occurs when only KS drivers exist in some PCS and when both drivers exist in some PCS：ErrorRsrcNfound: Insufficient location information or the device or resource is not present in the system.

This error occurred when I was trying to find the resource, and my code is as follows：

pub fn new(chn: String,instr_ip:String) -> Result<Self, String> {
        let rm = RESOURCE_DEFAULTRM.lock().map_err(|e| format!("{:?}", e))?;
        let ip_s = format!("TCPIP0::{}::inst0::INSTR", instr_ip);
        let expr = CString::new(ip_s)
            .map_err(|err| format!("{:?}", err))?
            .into();

        let rsc = rm.find_res(&expr).map_err(|op| format!("{:?}", op))?;

        let instr = rm
            .open(&rsc, AccessMode::NO_LOCK, TIMEOUT_IMMEDIATE)
            .map_err(|op| format!("{:?}", op))?;
        Ok(Self { instr, chn })
    }

I wonder if visa_rs can specify drivers that use KS or Ni, such as python's visa.resourceManager method

Hi! Currently, the driver can be specified only at compile time, by the path of visa64.lib set in LIB_VISA_PATH. Different drivers should be placed at separate folders, in C:\Program Files (x86)\IVI Foundation\VISA\WinNT on Windows. Based on my experience, you can try to connect the resource in Keysight Connection Expert GUI. If the GUI can do, visa-rs should work as well.
