have you tryed on linux OsTried on different PC running windows XP. Same problem again device driver not installed successfully. Installed drivers manually, no use.
Thanks a lot for your efforts. That 'Note' thing you did, why??? Seriously man. Right now I'm looking for an easy way out. So will probably buy new cableThere are few ckt if you can make it for your self
hope you have the good SMD soldering skills because FT232 is in SMD the driver for the same you may GOOOOOGLLLLLLLLLL

Thanks
Best of luck even Now i am planing to make the same even i don't need it only for experimental fun of SMD
First heavy shock Rs 450 μSoldering iron For SMD soldering Rest in coming weeksssssssssssssss
but i will let you know if it is completed successfully ofcourse not with out all ACC help
hats of to ACC gave me the reason to start the exp. with SMD
