      [PATCH] USB: Superficial improvements to hub_port_debounce() · f4692b3e
      Alan Stern authored 
      Since my previous suggestions for changes to hub_port_debounce()
encountered so much resistance, this patch makes some fairly superficial
improvements to the code while leaving the logic of the algorithm almost
completely intact.  The only behavioral change is that it actually
requests the port status at the start, rather than assuming the status is
not CONNECTED.  Changes include:

	Vastly improved comments that are now unambiguous and accurately
	descriptive of the code.

	Local variables changed to more sensible names.  The stability
	period is now reported in milliseconds rather than a meaningless
	poll count.

	The sleep interval is moved from the start of the loop to the
	end, so that the first time through we read the port status
	immediately.

	If the connection has not stabilized after the total timeout
	expires, -ETIMEDOUT is returned rather than whatever the
	current connect status happens to be.

	If the connection does stabilize then the port status is returned
	so that hub_port_connect_change() will have an up-to-date value
	for the status rather than relying on the pre-debounce value.

The changes I wanted to make but other people were worried about are
included as comments.  A later (small) patch will uncomment them for
testing.

      [PATCH] USB: Debounce all connect change events · 3e399447
      Alan Stern authored 
      This patch makes the hub driver debounce all connection changes.  Right
now the driver only does so if the status happens to be CONNECTED at one
particular instant.  However, the whole point of debouncing is that the
connection is subject to transient interruptions until it has stabilized;
hence deciding whether to debounce based on a single initial test defeats
the entire purpose.

There are some additional smaller changes that go along with the major
one:

	Comments added to hub_port_connect_change() detailing the
	conditions under which it will be called.

	Don't clear the port's connect-changed feature if it wasn't
	set.

	Skip debouncing if there wasn't a physical connection change
	but only a logical port-enable change (or a firmware-download-
	induced device morph -- not yet implemented).

	Clear all the hub status change indicators in hub_events()
	before handling a connect change.  This will reduce syslog
	clutter from status change bits that remain set while khubd
	is busy taking care of a new device.

The patch includes no changes to the debounce routine itself.  Please
apply.

      [PATCH] USB: Code cleanup for the UHCI driver · 5609e1a2
      Alan Stern authored 
      This patch makes some simple cleanups in the UHCI driver:

	It introduces msecs_to_jiffies() conversions and uses msleep().

	It wakes up threads waiting for an endpoint to be disabled
	in the oddball case where interrupts aren't working.  (This
	should have been in a previous patch but I missed it.)

	It disables PCI interrupt generation whenever the controller
	is reset and enables it when the controller is started.  This
	may possibly solve some people's problems with suspend/resume.

      [PATCH] USB: pegasus driver and ATEN device support · 9425c727
      Jan Spitalnik authored 
      I have created a patch to add support for ATEN device in pegasus usb driver.
I've sent the patch to the maintainer stated in pegasus.h but after several
weeks I didn't recieve a response, so I'm sending it to you now. The patch
should apply cleanly on 2.6.6, but it doesn't apply cleanly on todays -bk as
there was some patch adding some other device. One thing I'm not 100% sure
are the flags specified to PEGASUS_DEV, what means HAS_HOME_PNA?

      [PATCH] USB: kyocera 7135 patch · 8c670784
      Scott Cytacki authored 
      Here is a patch based on 2.6.7-rc2 that makes the Kyocera 7135 work.
The Kyocera appears to have the same setup as the Trio.  Its endpoints
are laid out like this:

> >>>type                  address
> >>>usb bulk out:         0x01
> >>>usb interrupt in:     0x82
> >>>usb bulk out:         0x03
> >>>usb bulk in:          0x84
The last two are the ones used for the syncing communication.

So the patch adds the ids for the kyocera and makes the treo_attach
function handle the kyocera too.  I also changed the comment; it appears
there was an error in the original comment about the treo:

Okay, I feel better.

It looks like those errors you see are caused by a bug in the usblp
driver.  The patch below ought to help.

      [Bluetooth] Move function exports out of syms.c · 784d9e34
      Marcel Holtmann authored 
      With Linux 2.6 there is no need to keep the function exports in a
central file and thus the use of syms.c makes no real sense. Remove
it and add the EXPORT_SYMBOL calls to the functions they belong to.
