FT232BM As a USB Host

Larry Wolcott

Hi Everyone,

·I've implemented the FT232BM on a MCU and it seems to be working fine connected to a PC. I need for the MCU to act as a HOST to a USB based GPS receiver. Can I rig the FT232BM to work in this manner, or am I forced to redesign?· Otherwise, can anyone point me in the right direction for something similar to the FT232BM that might also have host capabilities?

Cheers,

The FTDI chips are slave only. If all you want to do is speak from your device, to your peripheral, then USB is the wrong solution. There are far easier and more appropriate methods. There's a similar discussion over at

but the gist is - USB hosting is _hard_ if you want to do the full job of supporting arbitrary devices. If you don't need to support arbitrary devices that a user may choose to plug in, then try to find some other bus. For GPS, serial has to be a better option.
