HID: uclogic: Expose firmware name

2024-04-03T11:51:06+00:00

Some vendors reuse the same product ID for different tablets, making it
difficult for userspace to figure out which table is connected.
While matching the device name has been used in the past by userspace to
workaround this limitation, some devices have shown that this is not
always a valid approach [1].

However, if userspace could access the firmware version name, it would
be possible to know which tablet is actually connected by matching it
against a list of known firmware names [2].

This patch exposes the firmware version name in the hid->uniq field.

UClogic assorted fixes and new devices support (José Expósito)

HID: uclogic: Add support for XP-PEN Deco Pro MW

2023-01-18T08:44:57+00:00

The XP-PEN Deco Pro MW is a UGEE v2 device with a frame with 8 buttons,
a bitmap dial and a mouse. Its pen has 2 buttons, supports tilt and
pressure.

It can be connected using a USB cable or, to use it in wireless mode,
using a USB Bluetooth dongle. When it is connected in wireless mode the
device battery is used to power it.

All the pieces to support it are already in place. Add its ID and
quirks in order to support the device.

HID: uclogic: Add support for XP-PEN Deco Pro SW

2023-01-18T08:44:57+00:00

The XP-PEN Deco Pro SW is a UGEE v2 device with a frame with 8 buttons,
a bitmap dial and a mouse; however, the UCLOGIC_MOUSE_FRAME_QUIRK is
required because it reports an incorrect frame type. Its pen has 2
buttons, supports tilt and pressure.

It can be connected using a USB cable or, to use it in wireless mode,
using a USB Bluetooth dongle. When it is connected in wireless mode the
device battery is used to power it.

All the pieces to support it are already in place. Add its ID and
quirks in order to support the device.

HID: uclogic: Handle wireless device reconnection

2023-01-18T08:44:57+00:00

UGEEv2 tablets with battery can be connected using a USB cable or a USB
Bluetooth dongle.

When the Bluetooth dongle is used, the connection to that tablet can be
lost because the tablet is out of the range of the receiver or because
it was switched off using the switch placed in the back of the tablet's
frame.

After losing connection, the tablet is able to reconnect automatically
and its firmware sends a special packet indicating that the device was
reconnected. In response to this packet, the tablet needs to receive the
same array of magic data it expects on probe to enable its interfaces.

This patch implements a generic mechanism to hook raw events and
schedule a work to perform any custom action.

HID: uclogic: Refactor UGEEv2 probe magic data

2023-01-18T08:44:57+00:00

A fututure patch will need to use the array of magic data that the
UGEEv2 devices expect on probe and the endpoint number. Move them to a
common place.

Refactor, no functional changes.

HID: uclogic: Add battery quirk

2023-01-18T08:44:57+00:00

Some UGEE v2 tablets have a wireless version with an internal battery
and their firmware is able to report their battery level.

However, there was not found a field on their descriptor indicating
whether the tablet has battery or not, making it mandatory to classify
such devices through the UCLOGIC_BATTERY_QUIRK quirk.

HID: uclogic: Add frame type quirk

2023-01-18T08:44:57+00:00

The report descriptor used to get information about UGEE v2 devices is
incorrect in the XP-PEN Deco Pro SW. It indicates that the device frame
is of type UCLOGIC_PARAMS_FRAME_BUTTONS but the device has a frame of
type UCLOGIC_PARAMS_FRAME_MOUSE.

Here is the original report descriptor:

  0x0e 0x03 0xc8 0xb3 0x34 0x65 0x08 0x00 0xff 0x1f 0xd8 0x13 0x00 0x00
                                     ^ This byte should be 2

Add a quirk to be able to fix the reported frame type.

HID: uclogic: Add support for XP-PEN Deco LW

2022-11-04T14:53:25+00:00

The XP-PEN Deco LW is a UGEE v2 device with a frame with 8 buttons.
Its pen has 2 buttons, supports tilt and pressure.

It can be connected by USB cable or using a USB Bluetooth dongle to use
it in wireless mode. When it is connected using the dongle, the device
battery is used to power it.

Its vendor, product and version are identical to the Deco L. The only
difference reported by its firmware is the product name.
In order to add support for battery reporting, add a new HID descriptor
and a quirk to detect the wireless version of the tablet.
