From 82704c63b98202fe2a24032697369cd190202d3f Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Thu, 26 Jul 2012 14:31:40 +0200 Subject: USBDEBUG: buffer up to 8 bytes EHCI debug allows to send message with 8 bytes length, but we're only sending one byte in each transaction. Buffer up to 8 bytes to speed up debug output.
