From e06a055bcd966adf62a5653c84db781915392e41 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sat, 27 Feb 2010 21:32:17 +0300 Subject: [PATCH] EHCI: fix off-by-one error in ehci_submit_root() USB devices on the 2nd port are not detected and I get the following message: The request port(1) is not configured That's with default CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS value of 2. 'req->index' is 1-based, so the comparison in ehci_submit_root() can't be correct.
