INF file for custom device using Windows HID driver

[Dinesh]

Hi,
Summary of what I am doing:
----------------------------
I am using a custom device that has USB interface (HID class). I would like to use the device with Windows computer as host. For this purpose Windows native HID class driver is used in the host side. When I connect my custom device Windows OS detects it as HID compliant device and enumerates successfully Then I am able to transfer data using Control end point, interrupt IN and OUT end points.

After some investigation I found that Windows uses input.inf file for the custom device. But the device is shown as USB HID. So I need to have a INF file specific for my device to display custom device name, manufacturer and so on.

What I need?
-------------
Now my doubt is, should the INF file be signed/approved by Windows to avoid warning messages?

When I insert the custom device, I can see 2 branchs in the Device manager tree, one as HID-Compliant Device and other one as USB Human Interface Device. Is this behavior correct ?

Thanks for some help.

Best regards,
Dineshkumar M.

Your install package (ie. INF file) should be signed, to get priority over the default input.inf. Otherwise, Windows automatically assign input.inf without asking for your custom INF file.

Here is an example of custom HID INF file on MSDN
http://msdn.microsoft.com/en-us/library/windows/hardware/jj131716(v=vs.85).aspx

In this example, selective suspend is assigned to the target HID device, not just changing Manufacturer and device name of the device. If you don't need selective suspend feature, replace "HID_SelSus_Inst" into "HID_Inst"

Code: [Select]

[VendorXYZDevice_Install.NT]
include     = input.inf
;; needs    = HID_SelSus_Inst.NT
needs       = HID_Inst.NT

[VendorXYZDevice_Install.NT.HW]
include     = input.inf
;; needs    = HID_SelSus_Inst.NT.HW
needs       = HID_Inst.NT.HW

[VendorXYZDevice_Install.NT.Services]
include     = input.inf
;; needs    = HID_SelSus_Inst.NT.Services
needs       = HID_Inst.NT.Services

Just for custom device name, you may add FriendlyName registry entry after installation, using SetupDiSetDeviceRegistryProperty( SPDRP_FRIENDLYNAME )

If it is HID joystick, your device can provide its label, using "Windows OS string" - Extended Properties Descriptor
