Hi all, Been a while since I have been on here. I have a simple, yet very tightly budgeted, project I am working on. I need a way to convert USB to either ethernet or WIFI/bluetooth on a USB powered device. The board has a legacy device on it that I can't change nor can I touch the programming as well.

I am thinking of using a USB to serial converter like the FT232. Then depending on the requested install package, use a serial to ethernet or serial to wifi/bluetooth board. I know I will have to provide external power as the device will no longer be powered over USB.

If anyone has a better idea or has done something similar please let me know.

Unless that device can do USB OTG (and I don't think it can) then you'll have no hope of connecting it to an FT232. You need a host device to communicate between them.

The only thing I could suggest would be to connect it to a WF32 board and write a USB OTG driver for it, but how you'd do that I haven't the faintest clue - it all depends on how the USB is presented (what it emulates).
