Easily seen when a hub is connected with no device attached to it; it will autosuspend. When the hub is disconnected, it still shows up in /proc/bus/usb/devices Signed-off-by: Anand Gadiyar Acked-by: Felipe Balbi Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/usb/musb/musb_core.c b/drivers/usb/musb/musb_core.c index b120fdcd889..60cbaec1aa4 100644 --- a/drivers/usb/musb/musb_core.c +++ b/drivers/usb/musb/musb_core.c @@ -767,6 +767,7 @@ static irqreturn_t musb_stage2_irq(struct musb *musb, u8 int_usb, #ifdef CONFIG_USB_MUSB_HDRC_HCD case OTG_STATE_A_HOST: case OTG_STATE_A_SUSPEND: + usb_hcd_resume_root_hub(musb_to_hcd(musb)); musb_root_disconnect(musb); if (musb->a_wait_bcon != 0) musb_platform_try_idle(musb, jiffies
