From 255301fb507519b5cd022cfdb465d4963d186c5a Mon Sep 17 00:00:00 2001 From: Andreas Fritiofson Date: Mon, 25 Nov 2013 23:50:37 +0100 Subject: [PATCH] versaloon: Finish support for serial number matching Add a command to specify the serial string and pass it to the find helper. Actual matching was already supported for both serial and product but was using hard coded string indices. Instead use the indices from the device descriptor.
