Adding a new quirk tag to prevent ACM driver taking over the interfaces of a device which is not a real ACM device.

2011-05-11USB: cdc_acm: Fix oops when Droids MuIn LCD is connectedErik Slagter
The Droids MuIn LCD operates like a serial remote terminal. Data received are displayed directly on the LCD. This patch fixes the kernel null pointer oops when it is plugged in. Add NO_DATA_INTERFACE quirk to tell the driver that "control" and "data" interfaces are not separated for this device, which prevents dereferencing a null pointer in the device probe code.

2010-03-02USB: cdc_acm: Silence "It is not a modem." error for pbLua devicesJulian Calaby
The pbLua console port is known to not be a modem, so it is unnecessary to be told this when it is plugged in. Add NOT_A_MODEM quirk to tell the driver that we know this already and hence not to warn us, and mark the pbLua console port.

2009-08-07USB: fix oops on disconnect in cdc-acmOliver Neukum
This patch fixes an oops caused when during an unplug a device's table of endpoints is zeroed before the driver is notified. A pointer to the endpoint must be cached. this fixes a regression caused by commit 5186ffee2320942c3dc9745f7930e0eb15329ca6 Therefore it should go into 2.6.31 Signed-off-by: Oliver Neukum <oliver@neukum.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-08-13usb: cdc-acm: drain writes on closeDavid Brownell
Add a mechanism to let the write queue drain naturally before closing the TTY, rather than always losing that data. There is a timeout, so it can't wait too long. Provide missing locking inside acm_wb_is_avail(); it matters more now. Note, this presumes an earlier patch was applied, removing a call to this routine where the lock was held. Slightly improved diagnostics on write URB completion, so we can tell when a write URB gets killed and, if so, how much data it wrote first ... and so that I/O path is normally silent (and can't much change timings).

2008-08-13usb: cdc-acm: stop dropping tx buffersDavid Brownell
The "increase cdc-acm write throughput" patch left in place two now-obsolete mechanisms, either of which can make the cdc-acm driver drop TX data (nasty!). This patch removes them: - The write_ready flag ... if an URB and buffer were found, they can (and should!) always be used. - TX path acm_wb_is_used() ... used when the buffer was just allocated, so that check is pointless. Also fix a won't-yet-matter leak of a write buffer on a disconnect path.

2008-04-24USB: increase cdc-acm write throughputDavid Engraf
the following patch uses 16 write urbs and a writsize of wMaxPacketSize * 20. With this patch I get the maximum througput from my linux system with 20MB/sec read and 15 MB/sec write (full speed 1 MB/sec both) I also deleted the flag URB_NO_FSBR for the writeurbs, because this makes my full speed devices significant slower.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
