    Anyone using WinUSB?

              We are having some really random heap corruption issues calling cyusb.sys DeviceIOControl functions from managed code using IOCompletion ports. I can run my device and process millions of transactions using this code before it crashes. Sometimes it takes 20 minutes to crash sometimes takes 12 hours...   
      Anyway, I wanted to try a different driver just to see if, perhaps cyusb.sys was at fault.   
      I can try Jungo free for 30 days but balk at paying the price for the drivers if somehow switching over solves my problem. So, I was thinking of using the generic WinUSB drivers...(I realize of course I'll have to re-write parts of my code for the MS API) I am also not using any Iso endpoints either. So, It should work.   
      I'm just wondering if anyone here has had any success with drivers other than CyUSB.
