NI-VISA and PIC24FJ256GB206 & PIC18F47j53

[tz2002]

Hi ,
Im using CCS compiler for PIC24FJ256GB206 & PIC18F47j53
to create USB_HID device.
Now I need it to work under NI-VISA .
I use the NI driver wizard which work O.K
In the firmware , I create command to WRITE only
that set digital output ON & OFF. this works O.K.
but trying to use READ like *IDN? return error , and while investigating
its seems that it came from Bulk In/Out Pipe definitions.
probably I need to change something in the usb_desc_hid.h file.

Any idea what I need to change in the descriptor file , in order VISA READ/QUERY will work O.K ?

thanks..
T.Z.
