Given that our machines are used for testing on a nightly basis, 'devcon dp_enum' shows hundreds and hundreds of instances for the device that I am trying to test. The drivers are picked up from our build server, signed, and installed using devcon update.
One machine, for example, has oem*.inf files up to oem1259.inf; we have reason to believe that the huge number of cached driver versions is causing performance problems loading and unloading the driver.
Is it possible to use 'devcon dp_delete', or achieve the same functionality using other commands, to clean up these files in bulk? It would really be a good experiment to see if it speeds things up
