Visadev parallel instrument communication

I have written code to communicate with multiple visadev devices. I am using something along the lines of

response1 = writeread(device1,"READ?");
response2 = writeread(device2,"READ?");

in a loop to trigger the devices and get the response. This is far from ideal because the data from device 1 is returned much faster than from device 2 (due to the instruments being different), 'slowing down' device 1 as well. I would like to have device 1 return responses at a higher frequency. From several Matlab Answers suggestions, it seemed like this could be done with pareval or spmd.

This I did not manage to get to work:

dev = visadev( );                   % visadev connection to some device
rdev = @(device) readdev(device)    % need an anonymous function to pass to parfeval?
p = parpool(2);
Fdev = parfeval(p,rdev,1,dev)       % attempt to parfeval

function response = readdev(device)    
    response = writeread(device,"*IDN?")    % something any device can respond to
end

Fdev returns an error:

Error: Property assignment is not allowed when the object is empty. Use subscripted assignment to create an array

element.

VisaClient>VisaClient.disableErrorOnRead (line 0)

Resource>Resource.writeread (line 803)

test_pardevice>readLS (line 31)

test_pardevice>@(device)readLS(device) (line 17)

This was also mentioned in this thread.

An alternative suggestion I often see on Matlab Answers is to make a callback function. The configureCallback function that I guess I should be using is however no longer supported.

Could you suggest an approach to this problem?
