USB: qcserial/option: make AT URCs work for Sierra Wireless MC73xx

2015-01-07T09:12:25+00:00

As has been discussed in the thread starting with
https://lkml.kernel.org/g/549748e9.d+SiJzqu50f1r4lSAL043YSc@arcor.de
Sierra Wireless MC73xx devices with USB VID/PID 0x1199:0x68c0 require the
option_send_setup() code to be used on the USB interface for the AT port
to make unsolicited response codes work correctly. Move these devices from
the qcserial driver where they have been added by commit
70a3615fc07c2330ed7c1e922f3c44f4a67c0762 ("usb: qcserial: add Sierra Wireless
MC73xx") to the option driver and add a MC73xx-specific blacklist
to ensure that
1. the sendsetup code is not used for the DIAG/DM and NMEA interfaces
2. the option driver does not attach to the QMI/network interfaces

Add VID/PID for Telit LE910 modem. Interfaces description is almost the
same than LE920, except that the qmi interface is number 2 (instead than
5).

USB: serial: remove zte_ev driver

2014-09-15T16:43:08+00:00

The zte_ev driver is based on code (once) distributed by ZTE that still
appears to originally have been reverse-engineered and bolted onto the
generic driver.

A closer analysis of the zte_ev setup code reveals that it consists of
standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE)
but unfortunately fails to get some of those right. In particular, as
reported by Lei Liu, it fails to lower DTR/RTS on close. It also appears
that the control requests lack the interface argument.

Since line control is already handled properly by the option driver, and
the SET/GET_LINE_CODING requests appears to be redundant (amounts to a
SET 9600 8N1) let's remove the redundant zte_ev driver.

Also move the remaining ZTE PIDs to the generic option modem driver.

Revert "USB: option,zte_ev: move most ZTE CDMA devices to zte_ev"

2014-08-18T11:09:25+00:00

This reverts commit 73228a0538a7 ("USB: option,zte_ev: move most ZTE
CDMA devices to zte_ev").

Move the IDs of the devices that were previously driven by the option
driver back to that driver.

As several users have reported, the zte_ev driver is causing random
disconnects as well as reconnect failures.

A closer analysis of the zte_ev setup code reveals that it consists of
standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE)
but unfortunately fails to get some of those right. In particular, as
reported by Liu Lei, it fails to lower DTR/RTS on close. It also appears
that the control requests lack the interface argument.

Note that the zte_ev driver is based on code (once) distributed by ZTE
that still appears to originally have been reverse-engineered and bolted
onto the generic driver.

Since line control is already handled properly by the option driver, and
the SET/GET_LINE_CODING requests appears to be redundant (amounts to a
SET 9600 8N1), this is a first step in ultimately removing the redundant
zte_ev driver.

Note that AC2726 had already been moved back to option, and that some
IDs were in the device table of both drivers prior to the commit being
reverted.

USB: option: reduce interrupt-urb logging verbosity

2014-08-18T09:05:37+00:00

Do not log normal interrupt-urb shutdowns as errors.

The option driver has always been logging any nonzero interrupt-urb
status as an error, including when the urb is killed during normal
operation.

Commit 9096f1fbba91 ("USB: usb_wwan: fix potential NULL-deref at
resume") moved the interrupt urb submission from port probe and release
to open and close, thus potentially increasing the number of these
false-positive error messages dramatically.
