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 ?
