From: 0dbell on 1 Jun 2007 07:50 I am trying to use devcon.exe to ease the pain of repetitively re- installing a device driver under development for test & debug purposes. The device driver I am developing is based on MSVA (i.e. has no real hardware). When I attemp invoking it like this: devcon.exe update msvad.inf I get the error message: "devcon.exe: Invalid use of update." It seems that it also requires hwid as the second parameter? So I typed: devcon.exe hwids * but all I get is: "No matching devices found." What could be not matching in the wild card * ????????? What does devcon.exe do? Does it work at all? Or am I so sleepless and tired that I can't even get a clue how to use a simple tool like this? Thanks, Don P.S. If there is another way to re-install a driver (specified by .inf and a path to the actual location of the .sys driver file) without the annoying required mouse clicking on the update driver wizard, I would appreciate describing it here.
From: Gianluca Varenni on 1 Jun 2007 13:43 devcon update works for plug and play devices only (in fact you don't have an HWID). I would try to use devcon install (although i'm not 100% sure it will work, and i cannot find the this MSVA sample).

I actually meant to write MSVAD sample, not MSVA. This was a typo. I actually only need a way to copy over the .sys driver file each time I recompile to test and debug. However, just copying over the older copy doesn't mean the driver is reloaded. Is there a way to accomplish that? (devcon.exe is simply too cumbersome and seems to not be working in my case). Thanks, Don
From: Gianluca Varenni on 1 Jun 2007 18:48 For a non-pnp driver the easiest way is issuing a "net stop <drivername>" followed by a "net start <drivername>" on the command prompt.

My driver is not a network driver but rather an audio driver. I don't think NET STOP would do anything here. Or am I wrong? Thanks, Don |
