HID Driver + Company Name and Device Model
PostPosted: Tue Jan 12, 2010 10:54 pm     Reply with quote

I created a device starting with the Ex_USB_HID driver in the examples section and expanded on that. The pic is a 18F4550.

What I'm trying to do, is in Device Manager under Human Interface Devices, to list my Device Name and Model like all the others listed in there.

All it shows is:
HID Compliant Device

The only way to tell it's my device is to look at the VID and PID.

Does anyone know where in the code I enter this information? I already entered the Custom Strings in the Descriptor file, and the Device model shows up properly when it's enumerated.

Thanks,
Richard

I thought, the respective constants in usb_desc_hid.h are self-explanatory. Otherwise a text search for VID or PID should do.

Remember that to do this properly, _you_ need to own a VID/PID. Otherwise the combination you use, may be somebody else's, which will cause disasters later.
USB_STRING_DESC

I thought I mentioned these "were" filled in and that information shows fine during the enumeration. They just do not show up in Device Manager.

I'm using the default VID/PID that came with the example. This product will always stay in house on dedicated embedded machines so there really isn't any chance of conflict. I will see what it takes for our own though. Wow, $2000 to $4000 for a VID, we surely will not be doing that.
