This patch (as1047) removes the USB_PERSIST Kconfig option, enabling
it permanently.  It also prevents the power/persist attribute from
being created for hub devices; there's no point in having it since
USB-PERSIST is always turned on for hubs.

This patch (as1057) fixes a problem with the X-Rite/Gretag-Macbeth
Eye-One Pro display colorimeter; the device crashes when it receives a
Set-Interface request.  A new quirk (USB_QUIRK_NO_SET_INTF) is
introduced and a quirks entry is created for this device.

This patch (as1033) adds a quirks entry and an unusual_devs entry for
the Actions Semiconductor flash drive.  This device has a 64-byte
string descriptor, which it doesn't terminate with a 0-length packet.

Oddly enough, the reporter's logs show that when the device was
plugged in at boot time, it changes its behavior completely -- it uses
a different product ID, product string descriptor, and bDeviceClass.

This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND
quirk.  Since autosuspend is disabled by default, we will let
userspace worry about which devices can safely be suspended.  Thus the
lengthy series of quirk entries is no longer needed, and neither is
the quirk ID.  I suppose someone might eventually run across a hub
that can't be suspended; let's ignore the possibility for now.

The patch also cleans up the hasty way in which autosuspend gets
disabled.  Setting udev->autosuspend_delay to -1 wasn't quite right,
because the value is always supposed to be a multiple of HZ.  It's
better to leave the delay value alone and set autosuspend_disabled,
which is what the quirk routine used to do.

This patch (as965) disables autosuspend by default for all USB devices

I would like have the attached patch added to Linux kernel. The three
usb flash memories listed in the patch are being used in Intel's
ClassmatePC and need USB_QUIRK_RESET_RESUME to work reliably when
resuming from ram.

That drive is quite odd. It has 2K sectors, times out getting string
descriptors and needs a quirk.

Recent versions of the Linux kernel auto-suspend attached USB devices.
After this happens to the Canon EOS 5D camera, the camera's interrupt endpoints
don't seem to wake back up correctly, causing further use with libgphoto2
to fail with a -114 "OS error in camera communication" error.

A similar fix is probably necessary for this camera in PTP mode, which
identifies as USB product id 0x3102, but we haven't tested this.

As part of our testing process, we tried the USB_QUIRK_RESET_RESUME
quirk also, it's not helpful in this case.

It appears that one reason the "iConnect"-labeled multi-card reader was

This patch (as859) makes the default USB autosuspend delay a module
parameter of usbcore.  By setting the delay value at boot time, users
will be able to prevent the system from autosuspending devices which
for some reason can't handle it.

The patch also stores the autosuspend delay as a per-device value.  A
later patch will allow the user to change the value, tailoring the
delay for each individual device.  A delay value of 0 will prevent
autosuspend.
