From 993fe4ab633eff4f04dd63e4751ccc2a6ea2d52e Mon Sep 17 00:00:00 2001 From: Oleg Seiljus Date: Tue, 27 Oct 2009 12:40:24 -0700 Subject: [PATCH] Signalyzer: H2 and H4 support This patch includes partial support for these new JTAG adapters. More complete support will require updates to the libftdi code, for EEPROM access.
