2011-06-27USB: Add new FT232H chip to drivers/usb/serial/ftdi_sio.cUwe Bonnes
appended patch adds support for the new FTDI FT232H chip. This chip is a single channel version of the dual FT2232H/quad FT4232H, coming with it's own default PID 0x6014 (FT2232H uses the same PID 0x6010 like FT2232C, FT4232H has also it's own PID). The patch was checked on an UM232H module and a terminal program with TX/RX shorted to that typing in the terminal reproduced the characters.

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.

2011-06-06USB: option Add blacklist for ZTE K3765-Z (19d2:2002)Torsten Hilbrich
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.

2011-06-06option: add Alcatel X200 to sendsetup blacklistDan Williams
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.

2011-05-17USB: option: add support for Huawei E353 deviceMarcin Gałczyński
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.

2011-04-13Revert "USB: sam-ba: add driver for Atmel SAM Boot Assistant (SAM-BA)"Johan Hovold
This reverts commit 90593899de83a6e6fdea563d058acd2f4334e3f9. SAM-BA devices identify themselves CDC-ACM devices and should be using the cdc-acm driver. Since commit 5b239f0aebd4dd6f85b13decf5e18e86e35d57f0 (USB: cdc-acm: Add pseudo modem without AT command capabilities) cdc-acm also binds to them. Note that the Atmel SAM-BA tools expect to use a USB-serial driver and thus require a symlink from /dev/ttyACMn to some /dev/ttyUSBm (with m < 30) to be able to select the device. This is simply a UI-issue that should be fixed by Atmel. Tested with the SAM-BA 2.10 tools and an Atmel at91sam9260-ek.

2011-02-25USB: serial drivers need to use larger bulk-in buffersAlan Stern
When a driver doesn't know how much data a device is going to send, the buffer size should be at least as big as the endpoint's maxpacket value. The serial drivers don't follow this rule; many of them request only 256-byte bulk-in buffers. As a result, they suffer overflow errors if a high-speed device wants to send a lot of data, because high-speed bulk endpoints are required to have a maxpacket size of 512. This patch (as1450) fixes the problem by using the driver's bulk_in_size value as a minimum, always allocating buffers no smaller than the endpoint's maxpacket size.
