[placid] | Just wondering is there a way (not brute force) to check if a usb | storage device is connected?
Hmmm. How do you identify "a usb storage device" to know that it is or isn't connected? You can certainly do something useful with wmi. eg, <code> import wmi c = wmi.WMI () for usb_disk in c.Win32_DiskDrive (InterfaceType="USB"): print usb_disk.Caption print usb_disk.PNPDeviceID </code> Now, assuming that the PNPDeviceID is unique enough for your purpose, you could probably do something with it to keep hold of it and then check later whether the same device is still inserted. One possibility is to use a WMI watcher to spot when devices are removed: <code> import wmi c = wmi.WMI () usb_watcher = c.watch_for ( notification_type="Deletion", wmi_class="Win32_DiskDrive", delay_secs=2, InterfaceType="USB" ) while True: usb_removed = usb_watcher () # can optionally timeout print usb_removed.PNPDeviceID </code> Lots of other possibilities, a polling loop, two watchers, one for creation one for deletion etc. Depends exactly what your requirements are.
