[Qemu-devel] FTDI USB Serial Device as USB Device

[Volkan YAZICI]

Hi,

We have a serial temperature device that is connected to the machine via
a USB converter. When device gets plugged in, Linux recognizes the
device and binds it appropriately.

  # dmesg | less
  usbcore: registered new driver usbhid
  drivers/usb/input/hid-core.c: v2.6:USB HID core driver
  usbcore: registered new driver usbserial
  drivers/usb/serial/usb-serial.c: USB Serial support registered for generic
  usbcore: registered new driver usbserial_generic
  drivers/usb/serial/usb-serial.c: USB Serial Driver core
  drivers/usb/serial/usb-serial.c: USB Serial support registered for FTDI USB Serial Device
  ftdi_sio 1-2:1.0: FTDI USB Serial Device converter detected
  drivers/usb/serial/ftdi_sio.c: Detected FT232BM
  usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB0
  usbcore: registered new driver ftdi_sio
  drivers/usb/serial/ftdi_sio.c: v1.4.3:USB FTDI Serial Converters Driver

But the problem is that this device should have been recognized by the
Microsoft Windows (running by qemu) as a USB device. Any kind of help
will be really appreciated.


Regards.

P.S. qemu runs with "-usb -usbdevice tablet" options.

I guess what you want is USB passthrough: -usbdevice host:0403:6001 for
instance.
