From 1264c3676e95427bba5d01e05c303d036a7f9eca Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Fri, 26 Dec 2008 23:05:04 -0800 Subject: Switch to libusb-1.0 and use async interface. The async libusb interface offers substantial performance benefits by not making each command wait for the reply. This makes talking over this interface almost reasonable.
