USB: quirks: add quirk for Focusrite Scarlett

2023-08-11T09:45:34+00:00

commit 9dc162e22387080e2d06de708b89920c0e158c9a upstream.

The Focusrite Scarlett audio device does not behave correctly during
resumes. Below is what happens during every resume (captured with
Beagle 5000):



//



The Scarlett disconnects and is enumerated again.

However from time to time it drops completely off the USB bus during
resume. Below is captured occurrence of such an event:



//
//




To fix the condition a user has to unplug and plug the device again.

With USB_QUIRK_RESET_RESUME applied ("usbcore.quirks=1235:8211:b")
for the Scarlett audio device the issue still reproduces.

Applying USB_QUIRK_DISCONNECT_SUSPEND ("usbcore.quirks=1235:8211:m")
fixed the issue and the Scarlett audio device didn't drop off the USB
bus for ~5000 suspend/resume cycles where originally issue reproduced in
~100 or less suspend/resume cycles.

USB: core: Add routines for endpoint checks in old drivers

2023-05-30T11:42:14+00:00

commit 13890626501ffda22b18213ddaf7930473da5792 upstream.

Many of the older USB drivers in the Linux USB stack were written
based simply on a vendor's device specification.  They use the
endpoint information in the spec and assume these endpoints will
always be present, with the properties listed, in any device matching
the given vendor and product IDs.

While that may have been true back then, with spoofing and fuzzing it
is not true any more.  More and more we are finding that those old
drivers need to perform at least a minimum of checking before they try
to use any endpoint other than ep0.

To make this checking as simple as possible, we now add a couple of
utility routines to the USB core.  usb_check_bulk_endpoints() and
usb_check_int_endpoints() take an interface pointer together with a
list of endpoint addresses (numbers and directions).  They check that
the interface's current alternate setting includes endpoints with
those addresses and that each of these endpoints has the right type:
bulk or interrupt, respectively.

Although we already have usb_find_common_endpoints() and related
routines meant for a similar purpose, they are not well suited for
this kind of checking.  Those routines find endpoints of various
kinds, but only one (either the first or the last) of each kind, and
they don't verify that the endpoints' addresses agree with what the
caller expects.

In theory the new routines could be more general: They could take a
particular altsetting as their argument instead of always using the
interface's current altsetting.  In practice I think this won't matter
too much; multiple altsettings tend to be used for transferring media
(audio or visual) over isochronous endpoints, not bulk or interrupt.
Drivers for such devices will generally require more sophisticated
checking than these simplistic routines provide.

USB: core: Don't hold device lock while reading the "descriptors" sysfs file

2023-03-03T10:40:08+00:00

commit 45bf39f8df7f05efb83b302c65ae3b9bc92b7065 upstream.

Ever since commit 83e83ecb79a8 ("usb: core: get config and string
descriptors for unauthorized devices") was merged in 2013, there has
been no mechanism for reallocating the rawdescriptors buffers in
struct usb_device after the initial enumeration.  Before that commit,
the buffers would be deallocated when a device was deauthorized and
reallocated when it was authorized and enumerated.

This means that the locking in the read_descriptors() routine is not
needed, since the buffers it reads will never be reallocated while the
routine is running.  This locking can interfere with user programs
trying to read a hub's descriptors via sysfs while new child devices
of the hub are being initialized, since the hub is locked during this
procedure.

Since the locking in read_descriptors() hasn't been needed for over
nine years, we can remove it.

usb: core: add quirk for Alcor Link AK9563 smartcard reader

2023-02-22T11:47:18+00:00

commit 303e724d7b1e1a0a93daf0b1ab5f7c4f53543b34 upstream.

The Alcor Link AK9563 smartcard reader used on some Lenovo platforms
doesn't work. If LPM is enabled the reader will provide an invalid
usb config descriptor. Added quirk to disable LPM.

Verified fix on Lenovo P16 G1 and T14 G3

usb: core: hub: disable autosuspend for TI TUSB8041

2023-01-24T06:11:50+00:00

commit 7171b0e261b17de96490adf053b8bb4b00061bcf upstream.

The Texas Instruments TUSB8041 has an autosuspend problem at high
temperature.

If there is not USB traffic, after a couple of ms, the device enters in
autosuspend mode. In this condition the external clock stops working, to
save energy. When the USB activity turns on, ther hub exits the
autosuspend state, the clock starts running again and all works fine.

At ambient temperature all works correctly, but at high temperature,
when the USB activity turns on, the external clock doesn't restart and
the hub disappears from the USB bus.

Disabling the autosuspend mode for this hub solves the issue.

usb: add NO_LPM quirk for Realforce 87U Keyboard

2022-11-25T16:40:26+00:00

commit 181135bb20dcb184edd89817831b888eb8132741 upstream.

Before adding this quirk, this (mechanical keyboard) device would not be
recognized, logging:

  new full-speed USB device number 56 using xhci_hcd
  unable to read config index 0 descriptor/start: -32
  chopping to 0 config(s)

It would take dozens of plugging/unpuggling cycles for the keyboard to
be recognized. Keyboard seems to simply work after applying this quirk.

This issue had been reported by users in two places already ([1], [2])
but nobody tried upstreaming a patch yet. After testing I believe their
suggested fix (DELAY_INIT + NO_LPM + DEVICE_QUALIFIER) was probably a
little overkill. I assume this particular combination was tested because
it had been previously suggested in [3], but only NO_LPM seems
sufficient for this device.

USB: add RESET_RESUME quirk for NVIDIA Jetson devices in RCM

2022-11-03T14:52:27+00:00

commit fc4ade55c617dc73c7e9756b57f3230b4ff24540 upstream.

NVIDIA Jetson devices in Force Recovery mode (RCM) do not support
suspending, ie. flashing fails if the device has been suspended. The
devices are still visible in lsusb and seem to work otherwise, making
the issue hard to debug. This has been discovered in various forum
posts, eg. [1].

The patch has been tested on NVIDIA Jetson AGX Xavier, but I'm adding
all the Jetson models listed in [2] on the assumption that they all
behave similarly.

usb: add quirks for Lenovo OneLink+ Dock

2022-10-26T11:19:20+00:00

commit 37d49519b41405b08748392c6a7f193d9f77ecd2 upstream.

The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream

These hubs suffer from two separate problems:

1) After the host system was suspended and woken up, the hubs appear to
   be in a random state. Some downstream ports (both internal to the
   built-in audio and network controllers, and external to USB sockets)
   may no longer be functional. The exact list of disabled ports (if
   any) changes from wakeup to wakeup. Ports remain in that state until
   the dock is power-cycled, or until the laptop is rebooted.

   Wakeup sources connected to the hubs (keyboard, WoL on the integrated
   gigabit controller) will wake the system up from suspend, but they
   may no longer work after wakeup (and in that case will no longer work
   as wakeup source in a subsequent suspend-wakeup cycle).

   This issue appears in the logs with messages such as:

     usb 1-6.1-port4: cannot disable (err = -71)
     usb 1-6-port2: cannot disable (err = -71)
     usb 1-6.1: clear tt 1 (80c0) error -71
     usb 1-6-port4: cannot disable (err = -71)
     usb 1-6.4: PM: dpm_run_callback(): usb_dev_resume+0x0/0x10 [usbcore] returns -71
     usb 1-6.4: PM: failed to resume async: error -71
     usb 1-7: reset full-speed USB device number 5 using xhci_hcd
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad?
     usb 1-6.1-port1: cannot disable (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: cannot reset (err = -71)
     usb 1-6.1-port1: Cannot enable. Maybe the USB cable is bad?
     usb 1-6.1-port1: cannot disable (err = -71)

2) Some USB devices cannot be enumerated properly. So far I have only
   seen the issue with USB 3.0 devices. The same devices work without
   problem directly connected to the host system, to other systems or to
   other hubs (even when those hubs are connected to the OneLink+ dock).

   One very reliable reproducer is this USB 3.0 HDD enclosure:
   152d:9561 JMicron Technology Corp. / JMicron USA Technology Corp. Mobius

   I have seen it happen sporadically with other USB 3.0 enclosures,
   with controllers from different manufacturers, all self-powered.

   Typical messages in the logs:

     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     usb 2-1.4: device not accepting address 6, error -62
     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     usb 2-1.4: device not accepting address 7, error -62
     usb 2-1-port4: attempt power cycle
     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     usb 2-1.4: device not accepting address 8, error -62
     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command
     usb 2-1.4: device not accepting address 9, error -62
     usb 2-1-port4: unable to enumerate USB device

Through trial and error, I found that the USB_QUIRK_RESET_RESUME solved
the second issue. Further testing then uncovered the first issue. Test
results are summarized in this table:

=======================================================================================
Settings                        USB2 hotplug    USB3 hotplug    State after waking up
---------------------------------------------------------------------------------------

power/control=auto              works           fails           broken

usbcore.autosuspend=-1          works           works           broken
OR power/control=on

power/control=auto              works (1)       works (1)       works
and USB_QUIRK_RESET_RESUME

power/control=on                works           works           works
and USB_QUIRK_RESET_RESUME

HUB_QUIRK_DISABLE_AUTOSUSPEND   works           works           works
and USB_QUIRK_RESET_RESUME

=======================================================================================

In those results, the power/control settings are applied to both hubs,
both on the USB2 and USB3 side, before each test.

From those results, USB_QUIRK_RESET_RESUME is required to reset the hubs
properly after a suspend-wakeup cycle, and the hubs must not autosuspend
to work around the USB3 issue.

A secondary effect of USB_QUIRK_RESET_RESUME is to prevent the hubs'
upstream links from suspending (the downstream ports can still suspend).
This secondary effect is used in results (1). It is enough to solve the
USB3 problem.

Setting USB_QUIRK_RESET_RESUME on those hubs is the smallest patch that
solves both issues.

Prior to creating this patch, I have used the USB_QUIRK_RESET_RESUME via
the kernel command line for over a year without noticing any side
effect.

Thanks to Oliver Neukum @Suse for explanations of the operations of
USB_QUIRK_RESET_RESUME, and requesting more testing.

This turned out not to be an error in usb-storage but rather a nested
device reset attempt.  That is, as the rtl8712 driver was being
unbound from a composite device in preparation for an unrelated USB
reset (that driver does not have pre_reset or post_reset callbacks),
its ->remove routine called usb_reset_device() -- thus nesting one
reset call within another.

Performing a reset as part of disconnect processing is a questionable
practice at best.  However, the bug report points out that the USB
core does not have any protection against nested resets.  Adding a
reset_in_progress flag and testing it will prevent such errors in the
future.
