From b05f6dfed563db7c6d89e60d0fcf4d5bf8c03867 Mon Sep 17 00:00:00 2001 From: Michael Gernoth Date: Sun, 23 May 2010 23:10:41 +0200 Subject: [PATCH] Add initial parallel port support for ISE 12. Only ports existing on the local system can be used for real or ftdi-emulated cables. So you can't attach a ftdi-cable to your non-existant LPT4 currently. --- usb-driver.c | 22 ++++++++++++++++++++-- 1 file changed, 20 insertions(+), 2 deletions(-) diff --git a/usb-driver.c b/usb-driver.c index 3bfeee5..ff47ae3 100644 --- a/usb-driver.c +++ b/usb-driver.c @@ -659,8 +659,10 @@ int semop (int __semid, struct sembuf *__sops, size_t __nsops) { #endif /* - * Ugly hack for ISE 12.
