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 ..
Ah ok, thanks for  the details, it indeed looks like the handling of
this INSTALLING state is currently missing in device_added_cb().

Dear Mr Christophe          unfortunately, the test result was failed , when I added the contidion SPICE_USB_DEVICE_STATE_INSTALLING  , the USB device is always keeped  'check' state . In the usb-device-manager I just wrote a function() to call the static method 'spice_usb_device_get_state()' then obtain the return value to usb-device -widget .. but i don't know why it always keep installing state  or I used incorrect value to compare in my condition  ..Do you know how to modify this bug ?
