Hello, We have some USB devices attached to an EHCI chip which get themselves wedged sometimes, and we would like to power cycle them using the EHCI's ability to control power to the USB device. Is this possible? I found a function in ehci-hcd.c that might do what we want: http://lxr.linux.no/linux+v2.6.30/drivers/usb/host/ehci-hcd.c#L408 Will that do it? Who calls that function, and how can I trigger it? I found another message which suggests there's a /sys entry (and hence, a userspace way) to do it: https://lists.linux-foundation.org/pipermail/linux-pm/2005-March/006596.html But I can't find these on my machine. Any suggestions on how to get them? Thank you for your help!
