Description: Atmel CPUs come at internal 1Mhz clock. To use USBasp you need to use a SPI clock under 1/4 of the clock, menas under 250Khz. By default the USBasp uses 375Khz and is unuseable for new AVR CPUs. This file (must rename to usbdrv.c before compile) is fixed to cover that.

Description: HIDKey
BootloadHID is a USB boot loader for AVR microcontrollers.-his is the README file for bootloadHID.
BootloadHID is a USB boot loader for AVR microcontrollers. It can be used on
all AVRs with at least 2 kB of boot loader section, e.g. the popular ATMega8.
The firmware is flashed into the upper 2 kB of the flash memory and takes
control immediately after reset. If a certain hardware condition is met
(this condition can be configured, e.g. a jumper), the boot loader waits for
data on the USB interface and loads it into the remaining part of the flash
memory. If the condition is not met, control is passed to the loaded firmware.
This boot loader is similar to Thomas Fischl s avrusbboot, except that it
is built on top of the HID device class. This implementation is more user
friendly on Windows, since no kernel level drivers need to be installed.

Description: This the README file for the HIDKeys USB device.
HIDKeys is an example application for implementing an USB keyboard conforming
to the USB Device Class Definition for Human Interface Devices (HID) . It is
based on Objective Development s firmware-only USB driver for Atmel s AVR
microcontrollers and accepts up to 17 key inputs on an ATMega8. The firmware
should be easily portable to an ATTiny2313 or other tiny devices. Since it
implements a standards compliant keyboard, no separate host software is
needed.
Objective Development s USB driver is a firmware-only implementation of the
USB 1.1 standard (low speed device) on cheap single chip microcomputers of
Atmel s AVR series, such as the ATtiny2313 or even some of the small 8 pin
devices. It implements the standard to the point where useful applications can
be implemented. See the file usbdrdv/usbdrv.h for features and limitations.-This is the README file for the HIDKeys USB device.
