      USB: ftdi_sio: fix hi-speed device packet size calculation · 895f28ba
      由 Mark Adamson 提交于 
      Added a function to set the packet size to be used based on the value from the
device endpoint descriptor.  The FT2232H and FT4232H hi-speed devices will have
wMaxPacketSize of 512 bytes when connected to a USB 2.0 hi-speed host, but will
use alternative descriptors with wMaxPacketSize of 64 bytes if connected to a
USB 1.1 host or hub.  All other FTDI devices have wMaxPacketSize of 64 bytes,
except some FT232R and FT245R devices which customers have mistakenly
programmed to have wMaxPacketSize of 0 - this is an error and will be
overridden to use wMaxPacketSize of 64 bytes.  The packet size used is
important as it determines where the driver removes the status bytes from the
incoming data.  If it is incorrect, it will lead to data corruption.

      USB: serial: FTDI: add high speed device support · 094c2e6d
      由 Mark Adamson 提交于 
      Added support for FTDI's USB 2.0 hi-speed devices - FT2232H (2
interfaces) and FT4232H (4 interfaces), including a new baud rate
calculation for these devices which can now achieve up to 12Mbaud by
turning off a divide by 2.5 in the baud rate generator of the chips.  In
order to achieve baud rates of <1200 baud, the divide by 2.5 must be
active.  The default product ID of the FT2232H is 0x6010 (same as the
FT2232C IC).  The default PID of the FT4232H is 0x6011.

      USB: FTDI-SIO new device ids · d46130ab
      由 Daniel Suchy 提交于 
      I would like to have added new device to usbserial/ftdi_sio driver.
These ids used USB track device (http://www.l-and-b.dk/access_alt.html).
They use differend device IDs, but it works as standard usb-serial
conventer.

      Fix oops on close of hot-unplugged FTDI serial converter · 80193195
      由 David Woodhouse 提交于 
      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: New device ID for ftdi_sio driver · 2542335c
      由 Jon K Hellan 提交于 
      Here's a new device ID for the ftdio_sio driver.
The diff is with linus's tree as of this morning.

The device is the RigExpert Tiny USB Soundcard Transceiver Interface for ham
radio.

(I didn't actually test this. A fellow ham couldn't get the device to work, and
I suggested binding the device ID using sysfs - see
"http://jk.ufisa.uninett.no/usb/". However, he had had moved on to other things
by then. I guess adding the device ID to the kernel "on spec" won't hurt.
The relevant part of cat /proc/bus/usb/devices shows:
