site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com When i load the filter scheme driver it matches on the content hint and successfully expose the IOMedia object.I can read/write on this IOMedia object successfully by manually creating file or directory on this exposed IOMedia volume. But when i execute the sample user space application tool i am always getting the following error: Couldn't find any matching. This error comes when user space application tool looks for the serviceObjects and it didn't find one. Note that the "registered" flag appears inside the angle brackets.

My guess is that you're trying to location your I/O Kit service using IOServiceGetMatchingService[s]. If so, the most common error is that these routines will only find /registered/ services. You should use the ioreg tool to make sure that your service is register. $ ioreg -w 0 [...] +-o IOMediaBSDClient <class IOMediaBSDClient, registered, matched, active, busy 0, retain count 6> This email sent to site_archiver@lists.apple.com
