AVR and USB is possible without external chip

[Tess]

Using USB with an AVR without external chip is possible ! !

Take a look here : http://www.obdev.at/products/avrusb/index.html

It's a driver for USB 1.1

AVR-USB is a firmware-only implementation of a USB 1.1 compliant low-speed device for Atmel's AVR microcontrollers. It runs on any AVR microcontroller which has at least 2 kB of Flash memory, 128 bytes RAM and can be clocked at 12 MHz. No UART, timer, input capture unit or other special hardware is required (except one edge triggered interrupt).

AVR-USB can be licensed freely under an Open Source compliant license or alternatively under a commercial license.

I wish an extra board with an USB connector and a library in BASIC.

Possible ?

I agree, Tess.

A similar project is here:

It would be really great to have something like this as well as a library to handle software USB.
