We then ran a test on it and found 2.2.13 was 3 times slower than 2.2.5! We haven't analyzed what made the difference (or in fact what changes we've introduced to 2.2.13 with the patch, other than the reported conflicts). Is there anyone that experienced the same fenomena? What might be the reason for this? USB, We've been working on an USB host controller interface for the MPC850 and now it works with the ACM driver. It doesn't support URB for now.
