From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniele Palmas Subject: [PATCH 1/1] drivers: net: usb: qmi_wwan: add QMI_QUIRK_SET_DTR for Telit PID 0x1201 Date: Mon, 10 Apr 2017 17:34:23 +0200 Message-ID: <1491838463-20299-1-git-send-email-dnlplm@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cc: netdev-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, linux-usb-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Daniele Palmas To: =?UTF-8?q?Bj=C3=B8rn=20Mork?= Return-path: Sender: linux-usb-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: netdev.vger.kernel.org Telit LE920A4 uses the same pid 0x1201 of LE920, but modem implementation is different, since it requires DTR to be set for answering to qmi messages. This patch replaces QMI_FIXED_INTF with QMI_QUIRK_SET_DTR: tests on LE920 have been performed in order to verify backward compatibility. Signed-off-by: Daniele Palmas --- Hi Bjørn, as a side note in latest kernels I had troubles with qmi devices (e.g. I/O error when using qmicli). I found your suggestion in libqmi mailing list to revert commit 833415a3e781a26fe480a34d45086bdb4fe1e4c0 cdc-wdm: fix "out-of-sync" due to missing notifications and this seems to work.
