USB: serial: add another 4N-GALAXY.DE PID to ftdi_sio driver

2011-06-08T20:48:30+00:00

E.g. newer CAN 2.0 A/B <=> USB 2.0 converters report idProduct=f3c2.

Revert "USB: option: add ID for ZTE MF 330"

2011-06-07T22:03:37+00:00

This reverts commit a559d2c8c1bf652ea2d0ecd6ab4a250fcdb37db8.

Turns out that device id 0x1d6b:0x0002 is a USB hub, which causes havoc
when the option driver tries to bind to it.

So revert this as it doesn't seem to be needed at all.

Thanks to Michael Tokarev and Paweł Drobek for working on resolving this
issue.

USB: option Add blacklist for ZTE K3765-Z (19d2:2002)

2011-06-06T22:58:57+00:00

The funtion option_send_status times out when sending USB messages
to the interfaces 0, 1, and 2 of this UMTS stick. This results in a
5s timeout in the function causing other tty operations to feel very
sluggish.

This patch adds a blacklist entry for these 3 interfaces on the ZTE
K3765-Z device.

I was also able to reproduce the problem with v2.6.38 and v2.6.39.

This is very similar to a problem fixed in

option: add Alcatel X200 to sendsetup blacklist

2011-06-06T22:58:14+00:00

This modem really wants sendsetup blacklisted for interfaces 0 and 1,
otherwise the kernel hardlocks for about 10 seconds while waiting for
the modem's firmware to respond, which it of course doesn't do.

A slight complication here is that TCT (who owns the Alcatel brand) used
the same USB IDs for the X200 as the X060s despite the devices having
completely different firmware and AT command sets, so we end up adding
the X060s to the blacklist at the same time.  PSA to OEMs: don't use the
same USB IDs for different devices.  Really.  It makes your kittens cry.

USB: option: add support for Huawei E353 device

2011-05-17T18:20:22+00:00

I am sharing patch to the devices/usb/serial/option.c. This allows
operation of Huawei E353 broadband modem using the “option” driver. The
patch simply adds new constant with proper product ID and an entry to
usb_device_id. I worked on the 2.6.38.6 sources. Tested on Dell inspiron
1764 (i3 core cpu) and brand new Huawei E353 modem, Fedora 15 beta.

Looking at the type of change, i doubt it has potential to introduce
problems in other parts of kernel or the driver itself.

drivers/usb/serial/opticon.c: Release resources on kmalloc failure

2011-05-13T22:51:08+00:00

Several resources have been allocated before this kmalloc failure, and thus
they should be released in this error handling code, as done in nearby
error handling code.

Bind only modem AT command endpoint to option module.

2011-04-30T00:05:06+00:00

Network interface is handled by upcoming gt_b3730 module.

Removed "GT-B3710" from comment, it is another modem with another USB ID.
