USB support

This is just a small report on my experiments with usb.
I've used AVR-USB-162 devboard form Olimex to make a USB-compatible programer. I tired to write a simple program based on LibUSB to interface with custom device (vendor-specific, not RS232 emulator).
Ther result is: A simple test of I2C signaling with 4 commands in ON/OFF style runs very slow! It takes about 2 minutes to completely read 24C16.
I guess the current architecture of PonyProg (as well as IC-Prog by the way) will not make it posible to program devices through USB as fast as RS232 allows. The only way to spead up this proces is to let board controller to write and read bytes.
Did anyone have any positive result with speed improvement?
