4d59d8a11383ebf0e0260ee481a4e766959fd7d9 "USB: Export URB statistics for powertop". There's no configuration option added in that commit (no suspicious ifdefs either), so it shouldn't be possible to disable it! And it's definitely earlier than 2.6.24. > I just loaded uhci_hcd again on my Thinkpad X60T (core-duo, intel > ich7-chipset) and 1 core immediately gets back to C2 and stays there. > I have only 1 usb-device which i cannot disconnect (internal > fingerprint reader) but i have no modules for it loaded or even > installed. > I don't think that should count as an "active" device. That's about as much as I can help. I suggest you ask the linux-usb-users mailing list - someone referred me there when I was asking about this sort of thing, and they were pretty responsive and helpful.
