It says it has an onboard PL2303 chip for USB to serial... You just need to download the drivers for the pl2303 serial to USB..

In other words you don't need another Serial to USB convertor... Just connect the Laptop to the USB plug on the dev board..

i have installed the driver, still not working

That doesn't make sense... The features clearly states USB.... If you must the serial port to program the 8051 you need a bootloader.

Which micro are you using? I used to use the phillips 51 series... They come with a bootloader installed...
