* USB: Fix debug output of ark3116Jan Engelhardt2007-05-23
| | | | | | | | | | | Fix debug output. Previously, it would output "0xFFFFFFB0" on 32-bit archs (and probably "0xFFFFFFFFFFFFFFB0" on 64-bits), because buf is taken as signed char, which is promoted to signed int, while %x always expects an unsigned int.

* USB: Onetouch - switch to using input_dev->dev.parentDmitry Torokhov2007-05-23
| | | | | | | | | | | | | In preparation for struct class_device -> struct device input core conversion, switch to using input_dev->dev.parent when specifying device position in sysfs tree. Also, do not access input_dev->private directly, use helpers.

* USB: remove short initial timeout for device descriptor fetchAlan Stern2007-05-23
| | | | | | | | | | | | | | | | | This patch (as905) removes a micro-optimization from the hub port initialization code. Previously we had been using a short timeout on the first attempt the read the device descriptor; now we will use the standard timeout length. It's not clear that the short timeout ever provided any benefit. And now we know of one case where it actually hurts: The device can't meet the short timeout and then it gets terminally confused. This fixes Bugzilla #8444. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: remove unneeded WARN_ONAlan Stern2007-05-23
| | | | | | | | | | | | | | | | This patch (as883) removes an out-of-date WARN_ON from the main HCD endpoint-disable routine. The warning is triggered whenever an endpoint is disabled while the root hub is suspended. In the past that may not have been legal, but it definitely is legal now. Merely unbinding a USB driver will do it. Furthermore, I've never seen any occurrences of this warning that really did signal an actual bug or error condition. At this point it has outlived its purpose. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* USB: more autosuspend timer stuffAlan Stern2007-05-23
| | | | | | | | | | | | | | | | | This patch (as879) ties up some loose ends from an earlier patch. These are things I didn't think to include at the time but which clearly belonged there. If an autosuspend fails because driver activity races with the autosuspend call, restart the autosuspend timer. When a device is resumed by an external request, it counts as device activity and should update the last_busy time so that the next autoresume won't occur immediately.

* EHCI: fix problem with BIOS handoffAlan Stern2007-05-23
| | | | | | | | | | | | | | | | This patch (as882) fixes a problem with the EHCI BIOS handoff. On my machine, the BIOS configures the controller and the handoff fails, leaving the controller configured. During resume-from-disk, this confuses ehci-hcd into thinking that the controller has not been tampered with. The problem is fixed by turning off the Configured Flag whenever a BIOS handoff is attempted, whether it succeeds or not.

This fails to generate distinct ids if 1. An id is constantly created and destroyed 2. A chunk of ids just beyond the current next_id value is occupied This in turn leads to an increased chance of connection request being mis-detected as a duplicate, sometimes for several retries, until next_id gets past the block of allocated ids. This has been observed in practice. As a fix, remember the last id allocated and start immediately above it. This also fixes a problem with the old code, where next_id might overflow and become negative. Signed-off-by: Michael S.
