title: Usb Driver on 64bit Windows
body: <p>I have a pretty generic 64bit driver based on bulkusb.sys in WDK. It's been working for years with an embedded program, but now it is needed to work on Vista 64.
  From all the documentation I've tried to look through there doesn't seem to be anything affecting it, except compiling it for the 64bit environment, and yet when I compile it with the AMD64 build environment, I get "driver not intended for this platform" error message when it's trying to open the sys.</p>
  
  <p>What could be the solution for this?</p>
  
  <p>Update:
  What exactly do you mean by "trying to open the sys"? In the log, when it tries to run the sys file of the driver(not error in the inf) it fails.
  What WDK version are you using? 7600.16385.0</p>
  
  <p>Are both building and trying to deploy on the same Vista x64 machine? 
  No, I'm building on 32bit xp, but I don't see how it matters, since I use the correct build environment.</p>
  
  <p>Is your driver signed with a cross-signed certificate? No, I've tried enabling unsigned drivers, and it didn't help, but I'm also not sure what will be going on with this subject at all, and if you can give me some info on that as well, it will be welcome.</p>
  
  <p>Is the right build environment chosen (chk/fre/amd64/win2k)?
  I've used chk-vista-amd64. Since it's for vista 64bit...</p>
