I have search the net, but only found some circuits for USB to RS-232.

This is tricky. USB to Serial convertors will not work here. In order to communicate with your usb programmer, you'll need a usb host. If your laptop has a pcmcia slot, it'll be much easier to get a pcmcia usb card.

Another solution is to open up your programmer and check if it is using a usb-to-serial convertor like pl2303 or ft232 chips. You can directly tap out the serial signals.

I think there is no chip available to

realize your intent, because these chips

has no space to live. most of us

do not need these chips. converting

USB to RS232 may make sense,

converting RS232 to USB make

no sense.
