Why limit yourself to USB, when your piece of hardware is not actually a USB device? (You could of course work on *making* the rpi into a USB device, if using libusb in the host application is very important for you.) > Now, I have some experience with libusb and if this usb bridge cable > allows me to talk to other computer as If I was talking to a regular > usb device, then I don't see why this would not work. Or correct me if > I'm wrong. You are wrong. USB makes a quite significant distinction between host and device. It is simply not possible to talk to a host as if you were talking to a device. While a TCP/IP based administrative tool is one good and very common approach, USB does make enumeration easier for simple applications. I understand the appeal, but again, don't limit yourself. For configuring an embedded device I would either choose TCP/IP (most likely over SSH) or indeed USB, but if USB then I would make very sure that the embedded Linux device *is* a USB device. http://www.raspberrypi.org/phpBB3/viewtopic.php?t=8089&p=97007 Explains that even if the software part would work, the rpi USB port is actually permanently wired to an ethernet chip. You lose. Look for an alternative platform which does what you want, instead of trying to design complicated software layers to compensate for what is essentially broken (for your purpose) hardware. //Peter -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
