USB pen drive

Hi, apart from the Vinculum hardware, is there any other shield or something to plug a pen drive to an arduino?

maybe something a little bit cheaper than the nearly 40 euros of the vinculum?

thank you

If you have an Arduino UNO you can re-write the firmware of the USB-to-Serial chip to make it a USB Host. That should get you close to talking to a USB flash drive. Another option is to use a USB SD-card adapter instead of a flash drive and then use an SD reader which is a much simpler interface than USB.

If you have an Arduino UNO you can re-write the firmware of the USB-to-Serial chip to make it a USB Host.

I doubt that will work. First, host firmware is quite a bit more complicated than function firmware. Second, the Uno would have to provide power to the +5V rail of the USB bus, rather than derive power from it. The way the Uno hardware works, that is not possible.
