2020-08-18Revert "HID: usbhid: do not sleep when opening device"Jiri Kosina
This reverts commit d3132792285859253c466354fd8d54d1fe0ba786. This patch causes a regression with quite a few devices, as probing fails because of the race where the first IRQ is dropped on the floor (after hid_device_io_start() happens, but before the 50ms timeout passess), and report descriptor never gets parsed and populated. As this is just a boot time micro-optimization, let's revert the patch for 5.9 now, and fix this properly eventually for next merge window.

2020-08-17HID: i2c-hid: Always sleep 60ms after I2C_HID_PWR_ON commandsHans de Goede
Before this commit i2c_hid_parse() consists of the following steps: 1. Send power on cmd 2. usleep_range(1000, 5000) 3. Send reset cmd 4. Wait for reset to complete (device interrupt, or msleep(100)) 5. Send power on cmd 6. Try to read HID descriptor Notice how there is an usleep_range(1000, 5000) after the first power-on command, but not after the second power-on command. Testing has shown that at least on the BMAX Y13 laptop's i2c-hid touchpad, not having a delay after the second power-on command causes the HID descriptor to read as all zeros. In case we hit this on other devices too, the descriptor being all zeros can be recognized by the following message being logged many, many times: hid-generic 0018:0911:5288.0002: unknown main item tag 0x0 At the same time as the BMAX Y13's touchpad issue was debugged, Kai-Heng was working on debugging some issues with Goodix i2c-hid touchpads. It turns out that these need a delay after a PWR_ON command too, otherwise they stop working after a suspend/resume cycle. According to Goodix a delay of minimal 60ms is needed. Having multiple cases where we need a delay after sending the power-on command, seems to indicate that we should always sleep after the power-on command. This commit fixes the mentioned issues by moving the existing 1ms sleep to the i2c_hid_set_power() function and changing it to a 60ms sleep.

2020-07-14HID: input: Fix devices that return multiple bytes in battery reportGrant Likely
Some devices, particularly the 3DConnexion Spacemouse wireless 3D controllers, return more than just the battery capacity in the battery report. The Spacemouse devices return an additional byte with a device specific field. However, hidinput_query_battery_capacity() only requests a 2 byte transfer. When a spacemouse is connected via USB (direct wire, no wireless dongle) and it returns a 3 byte report instead of the assumed 2 byte battery report the larger transfer confuses and frightens the USB subsystem which chooses to ignore the transfer. Then after 2 seconds assume the device has stopped responding and reset it. This can be reproduced easily by using a wired connection with a wireless spacemouse. The Spacemouse will enter a loop of resetting every 2 seconds which can be observed in dmesg. This patch solves the problem by increasing the transfer request to 4 bytes instead of 2. The fix isn't particularly elegant, but it is simple and safe to backport to stable kernels. A further patch will follow to more elegantly handle battery reports that contain additional data.

2020-07-07HID: lenovo: Fix spurious F23 key press report during resume from suspendHans de Goede
The Ultrabook Keyboard sends a spurious F23 key-press when resuming from suspend. GNOME uses F23 to toggle the touchpad on/off so this causes the OSD graphics for the touchpad toggle to show on resume. The keyboard does not actually have a F23 key, se we can simple fix it by marking the 0x00070072 HID usage, which normally is F23, to be ignored.

2020-06-24HID: apple: Disable Fn-key key-re-mapping on clone keyboardsHans de Goede
The Maxxter KB-BT-001 Bluetooth keyboard, which looks somewhat like the Apple Wireless Keyboard, is using the vendor and product IDs (05AC:0239) of the Apple Wireless Keyboard (2009 ANSI version) <sigh>. But its F1 - F10 keys are marked as sending F1 - F10, not the special functions hid-apple.c maps them too; and since its descriptors do not contain the HID_UP_CUSTOM | 0x0003 usage apple-hid looks for for the Fn-key, apple_setup_input() never gets called, so F1 - F6 are mapped to key-codes which have not been set in the keybit array causing them to not send any events at all. The lack of a usage code matching the Fn key in the clone is actually useful as this allows solving this problem in a generic way. This commits adds a fn_found flag and it adds a input_configured callback which checks if this flag is set once all usages have been mapped. If it is not set, then assume this is a clone and clear the quirks bitmap so that the hid-apple code does not add any special handling to this keyboard. This fixes F1 - F6 not sending anything at all and F7 - F12 sending the wrong codes on the Maxxter KB-BT-001 Bluetooth keyboard and on similar clones.

2020-06-19HID: Wiimote: Treat the d-pad as an analogue stickDaniel G. Morse
The controllers from the Super Nintendo Classic Edition (AKA the SNES Mini) appear as a Classic Controller Pro when connected to a Wii Remote. All the buttons work as the same, with the d-pad being mapped the same as the d-pad on the Classic Controller Pro. This differs from the behaviour of most controllers with d-pads and no analogue sticks, where the d-pad maps to ABS_HAT1X for left and right, and ABS_HAT1Y for up and down. This patch adds an option to the hid-wiimote module to make the Super Nintendo Classic Controller behave this way. The patch has been tested with a Super Nintendo Classic Controller plugged into a Wii Remote in both with the option both enabled and disabled. When enabled the d-pad acts as the analogue control, and when disabled it acts as it did before the patch was applied. This patch has not been tested with e Wii Classic Controller (either the original or the pro version) as I do not have one of these controllers. Although I have not tested it with these controllers, I think it is likely this patch will also work with the NES Classic Edition Controllers. Signed-off-by: Daniel G.

2020-06-16HID: input: do not run GET_REPORT unless there's a Resolution MultiplierPeter Hutterer
hid-multitouch currently runs GET_REPORT for Contact Max and again to retrieve the Win8 blob. If both are within the same report, the Resolution Multiplier code calls GET_FEATURE again and this time, possibly due to timing, it causes the ILITEK-TP device interpret the GET_FEATURE as an instruction to change the mode and effectively stop the device from functioning as expected. Notably: the device doesn't even have a Resolution Multiplier so it shouldn't be affected by any of this at all. Fix this by making sure we only execute GET_REPORT if there is a Resolution Multiplier in the respective report. Where the HID_QUIRK_NO_INIT_REPORTS field is set we just bail out immediately.

After commit c23e2043d5f7 ("HID: multitouch: do not filter mice nodes"), MT_CLS_WIN_8 also supports mouse nodes, hence make MT_CLS_WIN_8_DUAL redundant. Remove MT_CLS_WIN_8_DUAL accordingly.

2020-05-27HID: multitouch: enable multi-input as a quirk for some devicesBenjamin Tissoires
Two touchpad/trackstick combos are currently not behaving properly. They define a mouse emulation collection, as per Win8 requirements, but also define a separate mouse collection for the trackstick. The way the kernel currently treat the collections is that it merges both in one device. However, given that the first mouse collection already defines X,Y and left, right buttons, when mapping the events from the second mouse collection, hid-multitouch sees that these events are already mapped, and simply ignores them. To be able to report events from the tracktick, add a new quirked class for it, and manually add the 2 devices we know about.

2020-05-26HID: sony: Fix for broken buttons on DS3 USB donglesScott Shumate
Fix for non-working buttons on knock-off USB dongles for Sony controllers. These USB dongles are used to connect older Sony DA/DS1/DS2 controllers via USB and are common on Amazon, AliExpress, etc. Without the patch, the square, X, and circle buttons do not function. These dongles used to work prior to kernel 4.10 but removing the global DS3 report fixup in commit e19a267b9987 ("HID: sony: DS3 comply to Linux gamepad spec") exposed the problem. Many people reported the problem on the Ubuntu forums and are working around the problem by falling back to the 4.9 hid-sony driver. The problem stems from these dongles incorrectly reporting their button count as 13 instead of 16. This patch fixes up the report descriptor by changing the button report count to 16 and removing 3 padding bits.

2020-05-15HID: Add quirks for Trust Panora Graphic TabletCristian Klein
The Trust Panora Graphic Tablet has two interfaces. Interface zero reports pen movement, pen pressure and pen buttons. Interface one reports tablet buttons and tablet scroll. Both use the mouse protocol. Without these quirks, libinput gets confused about what device it talks to. For completeness, here is the usbhid-dump: ``` $ sudo usbhid-dump -d 145f:0212 003:013:001:DESCRIPTOR 1588949402.559961 05 0D 09 01 A1 01 85 07 A1 02 09 00 75 08 95 07 81 02 C0 C0 09 0E A1 01 85 05 09 23 A1 02 09 52 09 53 25 0A 75 08 95 02 B1 02 C0 C0 05 0C 09 36 A1 00 85 06 05 09 19 01 29 20 15 00 25 01 95 20 75 01 81 02 C0 003:013:000:DESCRIPTOR 1588949402.563942 05 01 09 02 A1 01 85 08 09 01 A1 00 05 09 19 01 29 03 15 00 25 01 95 03 75 01 81 02 95 05 81 01 05 01 09 30 09 31 09 38 09 00 15 81 25 7F 75 08 95 04 81 06 C0 C0 05 01 09 02 A1 01 85 09 09 01 A1 00 05 09 19 01 29 03 15 00 25 01 95 03 75 01 81 02 95 05 81 01 05 01 09 30 09 31 26 FF 7F 95 02 75 10 81 02 05 0D 09 30 26 FF 03 95 01 75 10 81 02 C0 C0 05 01 09 00 A1 01 85 04 A1 00 26 FF 00 09 00 75 08 95 07 B1 02 C0 C0 ``` Signed-off-by: Cristian Klein <cristian.klein@elastisys.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2020-05-06HID: asus: Fix mute and touchpad-toggle keys on Medion Akoya E1239THans de Goede
The mute key, is broken. All the consumer keys on the keyboard USB interface work normally, except for mute which only sends press events and never sends release events. The touchpad key sends the otherwise unused input report with a report-id of 5 on the touchpad interface. It too only sends press events. This also requires extra special handling since the multi-touch touchpad events and the KEY_F21 events for the touchpad toggle must not be send from the same input_dev (userspace cannot handle this). This commit adds special handlig for both, fixing these keys not working. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
