From 7949f4e16456183bae0bc19ffe92072a27d0553e Mon Sep 17 00:00:00 2001 From: Ken MacLeod <ken@bitsko.slc.ut.us> Date: Thu, 6 Aug 2009 14:18:27 -0500 Subject: [PATCH] USB: isp1362: fix pulldown register defines and conf logic HCHWCFG_PULLDOWN_DS2 and HCHWCFG_PULLDOWN_DS1 were swapped. Incorrect operator precedence in isp1362_hc_start() hid part of the problem. This fixes a problem where Port 1 in Host mode fails to see disconnects.
