Millisecond Forums

Hello everyone,
While working with Inquisit, I have faced some difficulties with making the Cedrus Response Pad RB-530 work with the file I created for my experiment.
I would like to use both a keyboard and the response pad for running a study, where the keyboard is used by default for instructions (i.e. <page instructions>) and the response pad is used for responding to experimental trials. 
I followed the guidelines available on the millisecond.com. Thus, I installed the appropriate driver, checked the correspondence between buttons and responses, specified them for valid response, correct response, etc., and inserted  "/ imputdevice = XID" in each trial code.
When I run the experiment, the Inquisit seems to not react to the buttons I have pressed, thus I keep receiving timeout messages instead of correct/incorrect feedback.The scripts itself worked well when I run this file customed for the keyboard responses only (without XID).
 My trials look like that:

<trial test1>
/ stimulustimes = [1 = test1; 251 = postmask]
/ inputdevice = XID
/ validresponse = (3, 5) #Here, I was trying to set it to the response meanings, like (112, 176)
/ timeout = 1800
/ responsetrial = (3, correctmessage)
/ responsetrial = (5, errormessage)
/ responsetrial = (noresponse, timeoutmessage)
/ pretrialpause = 250
</trial>

At the same time, when I change the valid response to "anyresponse", the Inquisit does react to the buttons pressed, and I receive correct message feedback since any response is considered to be correct. 

<trial test1>
/ stimulustimes = [1 = test1; 251 = postmask]
/ inputdevice = XID
/ validresponse = (anyresponse)
...

Has anyone had similar problems with setting the validresponse buttons? Or maybe anyone knows what is wrong here? I would really appreciate any help.

Cheers,
Natalia
