[win32]g_iochannel and USB

[Manuel Ferrero <mferrero reer it>]

I'm trying to use a DLL for managing an USB connection.
In this DLL there is a function to open the USB channel wioth this 
prototype:
int CP210x_Open(DWORD dwDevice, HANDLE* cyHandle);

I thought I could link to that handle an iochannel, but I'm not able to 
make it work.

I wrote and compiled the following code:

---SNIP---
GIOChannel *USB_giochannel;
int USB_status;
HANDLE USB_handle;
DWORD USB_device;

USB_device = 1;

USB_status = CP210x_Open(USB_device, &USB_handle);
USB_giochannel = g_io_channel_win32_new_fd((int)USB_handle);
--PINS---

but when I run it I get the message:
GLib-WARNING **: g_io_channel_win32_new_fd: 1740 isn't an open file 
descriptor in the C library GLib uses.


What am I doing wrong?

mingw32-gcc version 3.4.5
GTK+ version 2.24.8
