Finding the Number of Endpoints of a NI USB Device

This article will specify the steps taken to find the number of endpoints of a USB-78XXR device.
Endpoints are physical devices that connect to and exchange information with a computer.

In order to follow this article, the installation of Windows SDK is necessary, specifically USBView app.

1. Open USBView app. Please note that a direct shortcut to the app might not be created on your PC. Please redirect to C:\Program Files (x86)\Windows Kits\10\Debuggers\x64
2. Connect the physical device to the Host PC.
3. Open My Computer tree, inside USBView interface and identify the device of interest.   
4. On the right side of the USBView interface, the information of your device will be specified. 
5. At the Interface Descriptor, under bNumEndpoints the total number of endpoints will be specified in a Hexadecimal format. 

After following the steps mentioned above with a NI USB-7855, the information found is the following:
