Wysocki" , Linux-pm mailing list hi Rafael, Alan: I recently meet a problem that I enable a usb disk's runtime auto autosuspend, set power/autosuspend_delay_ms to be 100 and make its usage_count to be 0. But after a long time, the disk's runtime status always is active. From my view, the disk's status should be "suspend" after the usage_count being 0 and delay timeout. If my opinion was wrong, please corrent me. Thanks. -- Best regards Tianyu Lan
