NI VISA USB RAW Bulk - In Read Timeout Error

[Vasanth_kumar]

Hi All,

I am working on NI-VISA to communicate with RAW USB.  I am trying to communicate an Instrument via USB RAW Bulk transfer through endpoints. This is not a NI Hardware/Instrument, it is a third party Instrument. I am not using multiple endpoints; I have fixed endpoints for Bulk-in (0x82) and Bulk-out (0x01).

I believe (I am not conclusive),  I have written the data through Bulk-out endpoint to my Instrument, as the return count terminal exactly shows the number of bytes that I am writing. I also want to know is there any other way to confirm the data been written into the Instrument.
The problem is that when I am trying to read the data from the Instrument, the NI-VISA Read function times out after 2000ms which is the default setting for the timeout. For your reference, I am attaching the different trials that I 
have tried for achieving the same. I am unable to read the data.
If someone can help me out of this will be appreciable. I went through few 
forums, I understood many have faced this issue. But, I haven't found any solution for the post.
Kindly forward me any support if you have worked on this issue before. Thanks in advance.

Hi

Which third party instrument is this? Is it emulating a serial port or do you really need raw USB?

[Vasanth_kumar]

Thanks for your response. The Hardware is 1553 card which has USB interface. I am not emulating a serial port, I need RAW USB Bulk-In/Out data transfer.
