14 years agousb: Fix issue with USB 3.0 devices after system resume
Sarah Sharp [Thu, 14 Oct 2010 14:22:54 +0000 (07:22 -0700)]
usb: Fix issue with USB 3.0 devices after system resume

When the system suspends and a host controller's power is lost, the USB
core attempts to revive any USB devices that had the persist_enabled flag
set.  For non-SuperSpeed devices, it will disable the port, and then set
the udev->reset_resume flag.  This will cause the USB core to reset the
device, verify the device descriptors to make sure it's the same device,
and re-install any non-default configurations or alternate interface
settings.

However, we can't disable SuperSpeed root hub ports because that turns off
SuperSpeed terminations, which will inhibit any devices connecting at USB
3.0 speeds.  (Plus external hubs don't allow SuperSpeed ports to be
disabled.)

Because of this logic in hub_activate():
                /* We can forget about a "removed" device when there's a
                 * physical disconnect or the connect status changes.
                 */
                if (!(portstatus & USB_PORT_STAT_CONNECTION) ||
                                (portchange & USB_PORT_STAT_C_CONNECTION))
                        clear_bit(port1, hub->removed_bits);

                if (!udev || udev->state == USB_STATE_NOTATTACHED) {
                        /* Tell khubd to disconnect the device or
                         * check for a new connection
                         */
                        if (udev || (portstatus & USB_PORT_STAT_CONNECTION))
                                set_bit(port1, hub->change_bits);

                } else if (portstatus & USB_PORT_STAT_ENABLE) {
                        /* The power session apparently survived the resume.
                         * If there was an overcurrent or suspend change
                         * (i.e., remote wakeup request), have khubd
                         * take care of it.
                         */
                        if (portchange)
                                set_bit(port1, hub->change_bits);

                } else if (udev->persist_enabled) {
                        udev->reset_resume = 1;
                        set_bit(port1, hub->change_bits);

                } else {
                        /* The power session is gone; tell khubd */
                        usb_set_device_state(udev, USB_STATE_NOTATTACHED);
                        set_bit(port1, hub->change_bits);
                }

a SuperSpeed device after a resume with a loss of power will never get the
reset_resume flag set.  Instead the core will assume the power session
survived and that the device still has the same address, configuration,
and alternate interface settings.  The xHCI host controller will have no
knowledge of the device (since all xhci_virt_devices were destroyed when
power loss was discovered, and xhci_discover_or_reset_device() has not
been called), and all URBs to the device will fail.

If the device driver responds by resetting the device, everything will
continue smoothly.  However, if lsusb is used before the device driver
resets the device (or there is no driver), then all lsusb descriptor
fetches will fail.

The quick fix is to pretend the port is disabled in hub_activate(), by
clearing the local variable.  But I'm not sure what other parts of the hub
driver need to be changed because they have assumptions about when ports
will be disabled.

scsi/sd: add a no_read_capacity_16 scsi_device flag

I seem to have a knack for digging up buggy usb devices which don't work
with Linux, and I'm crazy enough to try to make them work.  So this time a
friend of mine asked me to get an mp4 player (an mp3 player which can play
videos on a small screen) to work with Linux.

It is based on the well known rockbox chipset for which we already have an
unusual devs entries to work around some of its bugs.  But this model
comes with an additional twist.

This model chokes on read_capacity_16 calls.  Now normally we don't make
those calls, but this model comes with an sdcard slot and when there is no
card in there (and shipped from the factory there is none), it reports a
size of 0.  However this time the programmers actually got the
read_capacity_10 response right!  So they substract one from the size as
stored internally in the mp3 player before reporting it back, resulting in
an answer of ...  0xffffffff sectors, causing sd.c to try a
read_capacity_16, on which the device crashes.

This patch adds a flag to scsi_device to indicate that a a device cannot
handle read_capacity_16, and when this flag is set if a device reports an
lba of 0xffffffff as answer to a read_capacity_10, assumes it tries to
report a size of 0.

While working on supporting Appotech ax3003 based photoframes, which do

Looking at usb traces made under windows, windows never sends a

USB: disable endpoints after unbinding interfaces, not before

This patch (as1430) fixes a bug in usbcore.  When a device
configuration change occurs or a device is removed, the endpoints for
the old config should be completely disabled.  However it turns out
they aren't; this is because usb_unbind_interface() calls
usb_enable_interface() or usb_set_interface() to put interfaces back
in altsetting 0, which re-enables the interfaces' endpoints.

As a result, when a device goes through a config change or is
unconfigured, the ep_in[] and ep_out[] arrays may be left holding old
pointers to usb_host_endpoint structures.  If the device is
deauthorized these structures get freed, and the stale pointers cause
errors when the the device is eventually unplugged.

The solution is to disable the endpoints after unbinding the
interfaces instead of before.  This isn't as large a change as it
sounds, since usb_unbind_interface() disables all the interface's
endpoints anyway before calling the driver's disconnect routine,
unless the driver claims to support "soft" unbind.

This fixes Bugzilla #19192.  Thanks to "Tom" Lei Ming for diagnosing
the underlying cause of the problem.

USB: MUSB: fix kernel WARNING/oops when unloading module in OTG mode

musb_platform_exit() twice), unloading the driver module results in a WARNING

called." (or even kernel oops) on e.g. DaVincis, though only in the OTG mode.
There exists dubious and unbalanced put_device() call in musb_free() which
takes place only in the OTG mode.  As this commit caused musb_platform_exit()
to be called (and so unregister the NOP transceiver) before this put_device()
call, this function references already freed memory.

On the other hand, all the glue layers miss the otg_put_transceiver() call,
complementary to the otg_get_transceiver() call that they do.  So, I think
the solution is to get rid of the strange put_device() call, and instead
call otg_put_transceiver() in the glue layers...

USB: ftdi_sio: revert "USB: ftdi_sio: fix DTR/RTS line modes"

This reverts commit 6a1a82df91fa0eb1cc76069a9efe5714d087eccd.

RTS and DTR should not be modified based on CRTSCTS when calling
set_termios.

Modem control lines are raised at port open by the tty layer and should stay
raised regardless of whether hardware flow control is enabled or not.

This is in conformance with the way serial ports work today and many
applications depend on this behaviour to be able to talk to hardware
implementing hardware flow control (without the applications actually using
it).

Hardware which expects different behaviour on these lines can always
use TIOCMSET/TIOCMBI[SC] after port open to change them.

an USB ID for 0x0026.

drivers/usb/host/isp1362-hcd.c:1680: error: ‘ohci’ undeclared (first use in this function)

ohci variable is never declared and there isn't any CONFIG_USB_OTG dependent code
besides the portion defined in isp1362_hub_control.

So I think that maybe USB OTG support is not needed/supported.

This patch removes the CONFIG_USB_OTG dependent block so the driver can compile cleanly.
