USB RAW device shows up as Unknown Device Type in MAX

After installing the device driver for my USB RAW device using the Driver Wizard packaged with VISA 5.0.2, the device appears in Windows Device Manager under the category NI-VISA USB devices. But when I open MAX version 4.7.2f0 the device appears under Miscellaneous VISA Resources instead of the USB category. Also, the Device Type shows as Unknown, and when I try to open a VISA session it issues an error:

 

Unable to open session to "USB:: ... (resource name)

Return status code: 0xBFFF0011

Status name: VI_ERROR_RSRC_NFOUND

 

Insufficient location information or the device or resource is not present in the system.

 

I have followed the same installation procedure in various machines, some with Windows XP SP3 and one with Windows 7, and the results are the same for all. I would say that the driver is installed correctly in all cases since Windows can see it, but NI-VISA is unable to open it, why?

 

Note: The USB device is an Evaluation Board for a Cypress microcontroller (CY3214) but also I have tried with a USB mouse.
