USB to TTL level convertors cost around Rs 400 .
A good overview of all serial comm methods http://www.societyofrobots.com/microcontroller_uart.shtml
some basic details of how it is implemented and about the USB protocol http://www.atmel.com/Images/doc2556.pdf
Using firmware only ,there seems to be a couple of solutions.
1) V-Usb . Seems it needs a minimum of 12Mhz clock.
ATMega 32 can get a max of 16 Mhz with crystal. But 12 =MHz can be achieved using RC oscilator configuration
2) interface by Igor Cesko.
Has code for ATmega8 already.
Set of useful USB data http://www.frank-zhao.com/usnoobie/downloads.php
Am going to try out V-USb since it seems more mature and has more support.
