Universal Serial device

2015-12-06T07:41:43+02:00

Hello togheter,

my Atiny85 send via Vusb sample (using atmel2015 & USBasp) an Descriptor to host PC.
there bring my part into a Hid Class.

With my self maked *inf file i can bring em into the "Univerasl Serial device" class, and
give em an unique DeviceGUID (without the uid the part stay unaccessable)

My Question is how i must form out my device descriptor to become atomatical an "Universal Serial device"
I have Change PID and VID , with original Voti PID/VID the part jumps alone into this class, but stay unaccessable
how Long i dont install my handmaked *.inf with unique DeviceGUID

I can open the device with my hjandmaked *inf install (or automatic update with DevCon) fine.

I wich i dont Need some other Software and the part go alone into this class.

Oening wit CreateFile succs if the DeviceGUID is set via Inf only

Here the descriptor sampe to come as HID Input

Code:

PROGMEM const char usbHidReportDescriptor[22] = {    // USB report descriptor 
    0x06, 0x00, 0xff,              // USAGE_PAGE (Generic Desktop)
    0x09, 0x01,                    // USAGE (Vendor Usage 1)
    0xa1, 0x01,                    // COLLECTION (Application)
    0x15, 0x00,                    //   LOGICAL_MINIMUM (0)
    0x26, 0xff, 0x00,              //   LOGICAL_MAXIMUM (255)
    0x75, 0x08,                    //   REPORT_SIZE (8)
    0x95, 0x01,                    //   REPORT_COUNT (1)
    0x09, 0x00,                    //   USAGE (Undefined)
    0xb2, 0x02, 0x01,              //   FEATURE (Data,Var,Abs,Buf)
    0xc0                           // END_COLLECTION
};

This pack of data Comes from Arduino, i cant overlay that with the Structure from USB Spec

Code:

typedef struct {   
unsigned char bLength;                // Size of this Descriptor in Bytes   
unsigned char bDescriptorType;        // Descriptor Type (=1)   
unsigned int  bcdUSB;                 // USB Spec Release Number in BCD   
unsigned char bDeviceClass;           // Device Class Code   
unsigned char bDeviceSubClass;        // Device Subclass Code   
unsigned char bDeviceProtocol;        // Device Protocol Code   
unsigned char bMaxPacketSize0;        // Maximum Packet Size for EP0    
unsigned int  idVendor;               // Vendor ID    
unsigned int  idProduct;              // Product ID   
unsigned int  bcdDevice;              // Device Release Number in BCD   
unsigned char iManufacturer;          // Index of String Desc for Manufacturer   
unsigned char iProduct;               // Index of String Desc for Product   
unsigned char iSerialNumber;          // Index of String Desc for SerNo   
unsigned char bNumConfigurations;     // Number of possible Configurations 
} device_descriptor;

Equal what ever the descriptor send to host, when i later install my Inf , the device jump always
to the "Universal Serial device" class, that is what i will do with a own descriptor:

Code:

; KeyMan.inf
; Copyright (c) 1998-2015 KarstenSchulz

[Strings]
DeviceName = "KeyMan"
VendorName = "KarstenSchulz"
DeviceID   = "VID_16C1&PID_15DF" //my self maked pid/vid
DeviceGUID = "{EEBE3F79-3A2A-4304-9791-EBF0E998E93F}" //tha essential DeviceGUID without i cant never open the part

[USB_Install.Wdf]
KmdfService = WINUSB, WinUsb_Install

[USB_Install.HW]
AddReg = AddDeviceInterfaceGUID

[AddDeviceInterfaceGUID]
HKR,,DeviceInterfaceGUIDs,0x10000,%DeviceGUID%
HKR,,FriendlyName,,"KeyMan"

Thanks for any help how i can become an descriptor example or any Information about it,

Best regards
