From fe04314c2affada149f80858ee90e9b671ab9d25 Mon Sep 17 00:00:00 2001 From: Jaakko Kukkohovi Date: Wed, 21 Jan 2015 16:16:31 +0200 Subject: [PATCH] jtag/drivers/cmsis-dap-usb: fix cmsis_dap_serial MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Previously the serial wasn't actually used in hid_open() call, which meant that the first device with matching vid:pid was opened irrespective of the actual serial number.
