If you can find fully reliable usb to serial adapter in your area, then the idea given by IanP is better, as 8051 has UART and you can easily communicate using hyperterminal.
does anyone use usb to rs232 convertor to comunicate with microcontroller...
??whats the result of this if anyone has try it...and one thing usb to rs232 need driver to be installed on computer to work properly but we can not install driver on microcontroller....what is the solution of this...

i have tried rs232 to usb with atmega16 but it doesn't work all time when i connect usb i got unrecognized my usb port i installed drive for rs232 to usb cable in computer but still not worked i also need if possible solution to this
One of the simplest ways to add USB connectivity to a MCU with a UART is with FTDI FT232 or Silabs CP210x USB to UART Bridge device. Most parts suppliers have a breakout board with either or both devices making it relatively painless.
The FTDI device is more common, but I've had good success with both devices. I must have a dozen of these breakout boards in the lab, they make serial to USB connectivity a snap.
However, you can migrate to the PIC18F2550/4550 as Nanhu015 and will provide the USB connectivity you desire. There will be some additional coding and setup involved of course to implement the USB functions of the PIC.
