From a74171005f2f6474e05bdfccb05c9f0d68224a49 Mon Sep 17 00:00:00 2001 From: Gernot Hillier Date: Mon, 11 Jan 2010 09:35:17 +0100 Subject: [PATCH] USB: serial: option.c: Add 4G W14 stick to blacklist for option_send_setup The 4G XS Stick W14 seems to not understand RTS/DTR setting in option_send_setup causing long timeouts on any open() which disturbs a lot of well-known userspace applications like minicom or ModemManager. Therefore, we enable OPTION_BLACKLIST_SENDSETUP blacklisting for it.
