Are there any solutions out there to connect a USB port to a PIC micro, and communicate directly with PIC-style RS232 (+5V / 0V).  I
dont mind a bit of programming in VB or C++ to interface to the USB chip.

I am making a custom bootloader adaptor, with a 5-pin telephone adaptor to connect to the end product (just like on an MPLab-ICD).
This means I can unplug the MPLab-ICD telephone wire, plug in my bootloader, and get 5V power, and +5V PIC-based RS232 comms.

USB supplies 3.3V, so it would be cool to bump it up to 5V (the memory chip in my circuit needs 5V).

Any links or info on chipsets / custom solutions etc would be appreciated.

Cheers,
Shane.
