USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk> |
