codevision usb

hi everyone, i am writing C on atmega series with Codevision and i want to try AT90USB1286 for the first time. i have been through all the documentation on Atmel.com. I have viewed CDC and HID example codes for the device which have been provided in AVRstudio. Now the question is that does anyone know any USB library for these microcontrollers with Codevision? any hints? links? thanks.

the current version of the Codevision (1.25.3) does indeed support these devices, but it seems a library is needed to drive the USB controller on these devices. any hints?

After looking for a while I wrote my own driver in assembler by looking at the original code samples in C.

perhaps you can dig-in to the AVRfreaks it: www.avrfreaks.com and go to the forum section to dig information.
