[Spice-devel] [help]there's an error during i compile spice-gtk code

[hongzhen_luo at sina.com]

Dear Sir	 Thanks for you help, I have successful compiled my code .	 About the new interface spice_reget_usb_state(), it's for a bug  
      :that's  when I activated the usb device widget to click the check
 box for installing usb driver ,then closed(click X button) the device 
widget quickly and run the device widget again . 
       Normally ,the mark of checkbox should be remained ,but it's 
disappeared. So when you click again ,it will be popped up a message box
 : "Operation not supported or unimplemented on this platform"         So I checked the source code and found in the function : device_added_cb()       if (spice_usb_device_manager_is_device_connected(priv->manager,                                                     device))        gtk_toggle_button_set_active(GTK_TOGGLE_BUTTON(check), TRUE);       As,
 you see ,the condition was whether the device was connected ,if true 
the checkbox was set checked ,maybe for some reasons ,such as network 
delay or others ,  the usb needs more long time to redirect at Linux 
,however ,this interface(spice_usb_device_manager_is_device_connected)  just do judgement that it's whether has been connected ,probably
 .So when I operated quickly at device widget  (click checkbox -close 
widget -run widget -click check box) the mark was disappeared .      So  i want to add a  condition to get the current usb state ,if(spice_usb_device_manager_is_device_connected ||state == SPICE_USB_DEVICE_STATE_INSTALLING) {then .............} so  i write a method to get the state .      I didn't test the result yet ..maybe it will be successful maybe not ..
