Hi,

Read about V-USB, and this question is mostly for confirmation. Basically, V-USB is the firmware that resides on my AVR. To have the AVR talks with my computer (WINDOWS/LINUX/MAC OS), I still have to install a USB driver on my computer to talk my AVR. Correct? And I still have write that USB driver for my computer?

Thanks.

No, for the v-USB to work you only need a usb port Now getting the avr-studio and your ISP to work will involve some drivers. But if you write for example a HID and interface it with some hardware there is no need to install a driver as widows/linux will understand a HID descriptor.

In this respect, V-USB is in no way different than other USB devices. Most operating systems come with standard drivers for device classes and maybe some particular devices. If you can use one of these, you don't need your own driver.
