ChangeSet 1.1757.66.38, 2004/07/14 15:08:21-07:00, david-b@pacbell.net [PATCH] USB: usb hub, don't check speed before reset Signaling (even D- vs D+ pullup) may not be stable for a while. At least one OTG root hub won't reliably (<10%) report device speed until after reset (and the OTG state transitions have quiesced for a while). This patch makes that not matter.
