usb: new quirk to reduce the SET_ADDRESS request timeout

[ Upstream commit 5a1ccf0c72cf917ff3ccc131d1bb8d19338ffe52 ]

This patch introduces a new USB quirk,
USB_QUIRK_SHORT_SET_ADDRESS_REQ_TIMEOUT, which modifies the timeout value
for the SET_ADDRESS request. The standard timeout for USB request/command
is 5000 ms, as recommended in the USB 3.2 specification (section 9.2.6.1).

However, certain scenarios, such as connecting devices through an APTIV
hub, can lead to timeout errors when the device enumerates as full speed
initially and later switches to high speed during chirp negotiation.

In such cases, USB analyzer logs reveal that the bus suspends for
5 seconds due to incorrect chirp parsing and resumes only after two
consecutive timeout errors trigger a hub driver reset.

This 5-second delay in device enumeration is undesirable, particularly
in automotive applications where quick enumeration is crucial
(ideally within 3 seconds).

The newly introduced quirks provide the flexibility to align with a
3-second time limit, as required in specific contexts like automotive
applications.

By reducing the SET_ADDRESS request timeout to 500 ms, the
system can respond more swiftly to errors, initiate rapid recovery, and
ensure efficient device enumeration. This change is vital for scenarios
where rapid smartphone enumeration and screen projection are essential.

To use the quirk, please write "vendor_id:product_id:p" to
/sys/bus/usb/drivers/hub/module/parameter/quirks

For example,
echo "0x2c48:0x0132:p" > /sys/bus/usb/drivers/hub/module/parameters/quirks"

USB: quirks: add quirk for Focusrite Scarlett

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

<Suspend>
<Resume>
<Reset>/<Chirp J>/<Tiny J>
<Reset/Target disconnected>
<High Speed>

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:

<Suspend>
<Resume>
<Reset>/<Chirp J>/<Tiny J>
<Reset>/<Chirp K>/<Tiny K>
<High Speed>
<Corrupted packet>
<Reset/Target disconnected>

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.

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 quirks for Lenovo OneLink+ Dock

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 1-6.1-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 7, error -62

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 reverts commit 0bd860493f81eb2a46173f6f5e44cc38331c8dbd.

While the patch was working as stated,ie preventing the L850-GL LTE modem
from crashing on some U3 wake-ups due to a race condition between the
host wake-up and the modem-side wake-up, when using the MBIM interface,
this would force disabling the USB runtime PM on the device.

The increased power consumption is significant for LTE laptops,
and given that with decently recent modem firmwares, when the modem hits
the bug, it automatically recovers (ie it drops from the bus, but
automatically re-enumerates after less than half a second, rather than being
stuck until a power cycle as it was doing with ancient firmware), for
most people, the trade-off now seems in favor of re-enabling it by
default.

For people with access to the platform code, the bug can also be worked-around
successfully by changing the USB3 LFPM polling off-time for the XHCI
controller in the BIOS code.

The failure results from the ETIMEDOUT by chance when turning on
the suspend feature for the specified port of the hub. The port
seems to be in an unknown state so the hub_activate during resume
fails the hub_port_status, then the hub will fail to work.

The quirky hub needs the reset-resume quirk to function correctly.

USB: quirks: ignore remote wake-up on Fibocom L850-GL LTE modem

This LTE modem (M.2 card) has a bug in its power management:
there is some kind of race condition for U3 wake-up between the host and
the device. The modem firmware sometimes crashes/locks when both events
happen at the same time and the modem fully drops off the USB bus (and
sometimes re-enumerates, sometimes just gets stuck until the next
reboot).

Tested with the modem wired to the XHCI controller on an AMD 3015Ce
platform. Without the patch, the modem dropped of the USB bus 5 times in
3 days. With the quirk, it stayed connected for a week while the
'runtime_suspended_time' counter incremented as excepted.

USB: core: Fix regression in Hercules audio card

Commit 3e4f8e21c4f2 ("USB: core: fix check for duplicate endpoints")
aimed to make the USB stack more reliable by detecting and skipping
over endpoints that are duplicated between interfaces. This caused a
regression for a Hercules audio card (reported as Bugzilla #208357),
which contains such non-compliant duplications. Although the
duplications are harmless, skipping the valid endpoints prevented the
device from working.

This patch fixes the regression by adding ENDPOINT_IGNORE quirks for
the Hercules card, telling the kernel to ignore the invalid duplicate
endpoints and thereby allowing the valid endpoints to be used as
intended.

Add a USB_QUIRK_DISCONNECT_SUSPEND quirk for the Lenovo TIO built-in

seconds later by usb-audio disconnect interrupt to avoids the issue.

.......
Seeking a better fix, we've tried a lot of things, including:
- Check that the device's power/wakeup is disabled
- Check that remote wakeup is off at the USB level
- All the quirks in drivers/usb/core/quirks.c
e.g. USB_QUIRK_RESET_RESUME,
USB_QUIRK_RESET,
USB_QUIRK_IGNORE_REMOTE_WAKEUP,
USB_QUIRK_NO_LPM.

but none of that makes any difference.

There are no errors in the logs showing any suspend/resume-related issues.
When the system wakes up due to the modem, log-wise it appears to be a
normal resume.

Introduce a quirk to disable the port during suspend when the modem is
detected.

Testing revealed that disabling Link Power Management for the drive
fixed the problem.

This patch adds a quirk entry for that drive to turn off LPM permanently.

USB: quirks: Ignore duplicate endpoint on Sound Devices MixPre-D

The Sound Devices MixPre-D audio card suffers from the same defect
as the Sound Devices USBPre2: an endpoint shared between a normal
audio interface and a vendor-specific interface, in violation of the
USB spec. Since the USB core now treats duplicated endpoints as bugs
and ignores them, the audio endpoint isn't available and the card
can't be used for audio capture.

Along the same lines as commit bdd1b147b802 ("USB: quirks: blacklist
duplicate ep on Sound Devices USBPre2"), this patch adds a quirks
entry saying to ignore ep5in for interface 1, leaving it available for
use with standard audio interface 2.
