Hi Jens!

Thanks for the sample code. I've trimmed the recipient list a bit...

Not here either, but let me check, if I understand this correctly:

The "0xe1" in here is what is defined as "WIN_IDLEIMMEDIATE" in hdreg.h,
correct?

Hmm, don't I need to actually have *write* access for sending an ioctl?

I will give it another try, after clarifying the above questions - maybe
there is a command that will perform the desired task. If not, I guess
we're back at snooping what the Windows driver does here...
