USB: ftdi_sio: add vendor and product id for Bayer glucose meter serial converter cable

2009-08-16T21:19:03+00:00

commit c47aacc67a3d26dfab9c9b8965975ed2b2010b30 upstream.

Attached patch adds USB vendor and product IDs for Bayer's USB to serial
converter cable used by Bayer blood glucose meters. It seems to be a
FT232RL based device and works without any problem with ftdi_sio driver
when this patch is applied. See: http://winglucofacts.com/cables/

USB: ti_usb_3410_5052: fix duplicate device ids.

2009-07-30T21:39:14+00:00

commit 3c43f27bf57b0502df2478253699559ee1d43f6d upstream.

commit 1a1fab513734b3a4fca1bee8229e5ff7e1cb873c accidentally added the
device id to both tables in the driver, which causes problems as this is
only a single port device, not a multiple port device.

usb-serial: replace shutdown with disconnect, release

2009-07-02T23:50:25+00:00

commit f9c99bb8b3a1ec81af68d484a551307326c2e933 upstream

This patch splits up the shutdown method of usb_serial_driver into a
disconnect and a release method.

The problem is that the usb-serial core was calling shutdown during
disconnect handling, but drivers didn't expect it to be called until
after all the open file references had been closed.  The result was an
oops when the close method tried to use memory that had been
deallocated by shutdown.

usb-serial: fix crash when sub-driver updates firmware

2009-05-28T20:54:43+00:00

This patch (as1244) fixes a crash in usb-serial that occurs when a
sub-driver returns a positive value from its attach method, indicating
that new firmware was loaded and the device will disconnect and
reconnect.  The usb-serial core then skips the step of registering the
port devices; when the disconnect occurs, the attempt to unregister
the ports fails dramatically.

This problem shows up with Keyspan devices and it might affect others
as well.

When the attach method returns a positive value, the patch sets
num_ports to 0.  This tells usb_serial_disconnect() not to try
unregistering any of the ports; instead they are cleaned up by
destroy_serial().

Fix oops on close of hot-unplugged FTDI serial converter

2009-05-18T15:37:15+00:00

Commit c45d6320 ("fix reference counting of ftdi_private") stopped
ftdi_sio_port_remove() from directly freeing the port-private data, with
the intention if the port was still open, it would be freed when
ftdi_close() is eventually called and releases the last refcount on the
structure.

That's all very well, but ftdi_sio_port_remove() still contains a call
to usb_set_serial_port_data(port, NULL) -- so by the time we get to
ftdi_close() for the port which was unplugged, it _still_ oopses on
dereferencing that NULL pointer, as it did before (and does in 2.6.29).

The fix is just not to clear the private data in ftdi_sio_port_remove().
Then the refcount is properly reduced to zero when the final kref_put()
happens in ftdi_close().

Remove a bogus comment too, while we're at it. And stop doing things
inside "if (priv)" -- it must _always_ be there.

Based loosely on an earlier patch by Daniel Mack, and suggestions by
Alan Stern.

usb-serial: ftdi_sio: fix reference counting of ftdi_private

2009-05-09T02:34:57+00:00

This patch (as1238) adds proper reference counting for ftdi_sio's
private data structure.  Without it, the driver will free the
structure while it is still in use if the user unplugs the serial
device before closing the device file.

The patch also replaces a slightly dangerous
cancel_delayed_work/flush_scheduled_work pair with
cancel_delayed_work_sync, which is always safer.

USB: removal of tty->low_latency hack dating back to the old serial code

2009-04-23T21:15:29+00:00

This removes tty->low_latency from all USB serial drivers that push
data into the tty layer at hard interrupt context. It's no longer needed
and actually harmful.
