Hey, these are nice hints but I am not sure how to use them.
At the Moment I am working on the "HIDKeys" project:

General Description:
This file contains parts of the USB driver which can be configured and can or
must be adapted to your hardware.
Please note that the usbdrv contains a usbconfig-prototype.h file now. We
recommend that you use that file as a template because it will always list
the newest features and options.

/* ---------------------------- Hardware Config ---------------------------- */
#define USB_CFG_IOPORTNAME D
/* This is the port where the USB bus is connected. When you configure it to
* "B", the registers PORTB, PINB and DDRB will be used.
*/

/* This is the bit number in USB_CFG_IOPORT where the USB D- line is connected.
* This may be any bit in the port.
*/
#define USB_CFG_DPLUS_BIT 2
/* This is the bit number in USB_CFG_IOPORT where the USB D+ line is connected.
* This may be any bit in the port. Please note that D+ must also be connected
* to interrupt pin INT0!
*/
/* ----------------------- Optional Hardware Config ------------------------ */
/* #define USB_CFG_PULLUP_IOPORTNAME D */
/* If you connect the 1.5k pullup resistor from D- to a port pin instead of
* V+, you can connect and disconnect the device from firmware by calling
* the macros usbDeviceConnect() and usbDeviceDisconnect() (see usbdrv.h).
* This constant defines the port on which the pullup resistor is connected.
*/
/* #define USB_CFG_PULLUP_BIT 4 */
/* This constant defines the bit number in USB_CFG_PULLUP_IOPORT (defined
* above) where the 1.5k pullup resistor is connected. See description

/* Define this to 1 if you also want to implement the ENDPOINT_HALT feature

* usbFunctionSetup(). This saves a couple of bytes.

* of the macros usbDisableAllRequests() and usbEnableAllRequests() in

/* We cannot use Obdev's free shared VID/PID pair because this is a HID.

/* ------------------- Fine Control over USB Descriptors ------------------- */
/* If you don't want to use the driver's default USB descriptors, you can
* provide our own. These can be provided as (1) fixed length static data in
* flash memory, (2) fixed length static data in RAM or (3) dynamically at
* runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
* information about this function.
* Descriptor handling is configured through the descriptor's properties. If
* no properties are defined or if they are 0, the default descriptor is used.
* Possible properties are:
* + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
* at runtime via usbFunctionDescriptor().
* + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
* in static memory is in RAM, not in flash memory.
* + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
* the driver must know the descriptor's length. The descriptor itself is
* found at the address of a well known identifier (see below).
* List of static descriptor names (must be declared PROGMEM if in flash):
* char usbDescriptorDevice[];
* char usbDescriptorConfiguration[];
* char usbDescriptorHidReport[];
* char usbDescriptorString0[];
* int usbDescriptorStringVendor[];
* int usbDescriptorStringDevice[];
* int usbDescriptorStringSerialNumber[];
* Other descriptors can't be provided statically, they must be provided
* dynamically at runtime.
*
* Descriptor properties are or-ed or added together, e.g.:
* #define USB_CFG_DESCR_PROPS_DEVICE (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
*
* The following descriptors are defined:
* USB_CFG_DESCR_PROPS_DEVICE
* USB_CFG_DESCR_PROPS_CONFIGURATION
* USB_CFG_DESCR_PROPS_STRINGS
* USB_CFG_DESCR_PROPS_STRING_0
* USB_CFG_DESCR_PROPS_STRING_VENDOR
* USB_CFG_DESCR_PROPS_STRING_PRODUCT
* USB_CFG_DESCR_PROPS_STRING_SERIAL_NUMBER
* USB_CFG_DESCR_PROPS_HID
* USB_CFG_DESCR_PROPS_HID_REPORT
* USB_CFG_DESCR_PROPS_UNKNOWN (for all descriptors not handled by the driver)
*

Then I add "-l" to the Custom compilation Options. The console output is now:

ok... I am not getting an idea what to do now. Adding "-M" to the Custom compilation Options gets this from the console:

I have got no idea. I have added the usbdrvasm.S and usbdrvasm.asm to "Other Files" in AVR Studio 4.18 build 716. What am I doing wrong?
