+ * Windows tries to fetch some special descriptors with informations

+ *
+ * compatid descriptor
+ * Used to bind drivers, if usb class isn't specific enougth.
+ * Used for PTP/MTP for example (both share the same usb class).
+ *
+ * properties descriptor
+ * Does carry registry entries. They show up in
+ * HLM\SYSTEM\CurrentControlSet\Enum\USB\<devid>\<serial>\Device Parameters
+ *
+ * Note that Windows caches the stuff it got in the registry, so when
+ * playing with this you have to delete registry subtrees to make
+ * windows query the device again:
+ * HLM\SYSTEM\CurrentControlSet\Control\usbflags
+ * HLM\SYSTEM\CurrentControlSet\Enum\USB
+ * Windows will complain it can't delete entries on the second one.
+ * It has deleted everything it had permissions too, which is enouth
+ * as this includes "Device Parameters".
