feat(atk): support the VXE R1 Pro over the 1K dongle - #306
Adding a VXE R1 Pro through its 0x3554:0xf58a "VXE NordicMouse 1K Dongle"
failed with "The mouse reported a DPI stage that failed its checksum." This
fixes the misidentification behind that error and enables the settings that
were captured from ATK HUB on real hardware.
Root cause
The dongle is not in the vendor catalog, so the driver falls back to a
CID/MID-only match.
The R1 Pro reports CID/MID 2,8. The only catalog entry with that pair is
the VXE R1 NK on 0x373b:0x124c, a PAW3395SE mouse.
The PAW3395SE codec has no code 0x07, so the 400-DPI stage 07 07 00 47
decoded to null and aborted the status read. The row's checksum was valid;
the error message was wrong.
CID/MID numbering restarts per USB vendor: 10 of the 12 Compx (0x3554) pairs
in the catalog name a different mouse under 0x373b.
Changes
Vendor-scoped catalog fallback. A CID/MID-only match is accepted only
when the entry belongs to the connected USB vendor. This only removes
matches; same-vendor behaviour is unchanged.
R1 Pro identity.2,8 under 0x3554 is registered as VXE R1 Pro,
PAW3395, R1 family.
Receiver writes. ATK HUB sends the R1 Pro the same rows as the R1 Pro
Max on this dongle, so the R1 Pro reuses the existing F58A write/echo
helpers.
DPI lighting Off. The R1 Pro keeps a Breathing effect pair stored and
carries Off in the enabled flag alone. The driver sends HUB's Off row, does
not require the effect pair to read back, and decodes enabled = 0 as Off for
this identity.
Brightness hint.ui.dpiLighting.brightnessModes (optional) lists the
modes that accept a brightness. Set to [1] for the R1 Pro and R1 Pro Max,
where the driver already leaves brightness alone while breathing.
Error message. A DPI row that sums correctly but cannot be decoded now
reports a likely misidentified model instead of a checksum failure.
Evidence
captures/vxe-r1-pro/receiver-atk-hub.txt and receiver-atk-hub-profiles.txt: ATK HUB (v3-hub.atk.store) changing each
setting, logged at the WebHID layer. The hub's session handshake and the
receiver RF identity are removed.
docs/vxe-r1-pro-testing.md: identity, per-setting rows, and what was not
tested.
Hardware verification
VXE R1 Pro, firmware 1.20, 0x3554:0xf58a receiver. Each setting was written
by the driver, confirmed by readback, and restored:
polling rate; DPI stage value, stage count, active stage
configuration bank 1-4, with read-only button assignments
The patched package was also installed into OpenMouse and used from the UI on
the same mouse.
Not covered
Wired transport: untested, stays read-only.
Button-assignment writes and macros: not implemented for any R1.
Performance Mode: ATK HUB shows no such switch for this mouse, so the driver
neither reports nor writes it.
DPI stage count was written by the driver, but HUB's own stage-count change
was not captured.
Sleep timer: HUB also writes the 0x00b5 row; the driver writes 0x00a9
only, as for the R1 Pro Max. Readback confirms the value; actual sleep
timing was not measured.
Testing
npm run check: build passes; 3062 of 3064 tests pass. The two failures
are Corsair setDpi tests that also fail on unmodified main on this
machine (they expect 2,400 and the local locale formats 2.400).
7 new ATK tests built from the captured frames.
OpenMouse npm run check passes with this package installed locally
(build, bundle size, 658 of 658 tests).
Summary by CodeRabbit
New Features
Added support for the VXE R1 Pro with its 1K receiver, including profile selection and settings for DPI, polling rate, lift-off distance, debounce, sleep timer, and other receiver options.
Added DPI lighting controls that reflect the R1 Pro’s available effects and brightness behavior.
Compatibility
Button assignments remain read-only. Wired operation and wired changes are untested, and Performance Mode is not supported.
The R1 Pro reports CID/MID 2,8 through the 0x3554:0xf58a dongle. The
dongle is not in the vendor catalog, so the driver matched the pair to
the VXE R1 NK (0x373b, PAW3395SE) and failed to decode a 400-DPI stage,
reporting it as a checksum failure.
- Accept a CID/MID-only catalog match only within the connected USB
vendor; the numbering restarts per vendor.
- Register 2,8 under 0x3554 as the VXE R1 Pro (PAW3395, R1 family).
- Reuse the F58A receiver write/echo helpers for the settings captured
from ATK HUB on the R1 Pro, including configuration banks.
- Handle the R1 Pro's DPI lighting Off state, which is carried by the
enabled flag alone.
- Add ui.dpiLighting.brightnessModes so a UI can lock brightness in
modes that ignore it (R1 Pro and R1 Pro Max: steady only).
- Report an undecodable DPI row with a valid checksum as a likely
misidentified model instead of a checksum failure.

Walkthrough
The ATK driver now identifies the VXE R1 Pro through its Compx receiver and supports verified receiver operations. Tests cover identification and device behavior. New USB captures and hardware notes record configuration exchanges, tested settings, and unsupported or unverified features.
Product and sensor lookup now accounts for the connected USB vendor. The driver maps Compx CID/MID 2,8 to the VXE R1 Pro, recognizes the model behind the verified receiver, and tests vendor-specific lookup behavior.
Receiver operations and validation src/drivers/atk/hid.ts, src/drivers/atk/r1-pro-max-hid.test.ts, src/drivers/mouse-types.ts
The driver handles R1 Pro status and receiver settings, including DPI stages, profile selection, and DPI lighting. It rejects Performance Mode writes and reports sensor-incompatible DPI data separately from checksum failures. Tests cover status and writes; the DPI-lighting UI hint adds supported brightness modes.
Hardware captures and verification notes captures/vxe-r1-pro/*, docs/vxe-r1-pro-testing.md
The captures record receiver settings and profile-bank exchanges, including a configuration that appears to be stored on the PC. The hardware notes document tested behavior and list unsupported or unverified features.
This adds VXE R1 Pro receiver support and fixes the misidentification of the device as a VXE R1 NK. One residual risk remains. If an application changes motion sync, ripple control or similar settings at the same time, one change can silently overwrite another. This is a small risk and can be fixed before or shortly after merge.

Explanation
The title "feat(atk): support the VXE R1 Pro over the 1K dongle" states the main change. The PR adds VXE R1 Pro support through the 0x3554:0xf58a 1K dongle, which the objectives and file summaries confirm. It uses a conventional type prefix and names the device and transport, so a teammate scanning history can identify the primary change.

- Line 1675: Serialize the full read-modify-write transaction in
writeR1ProMaxReceiverAdvanced and writeAdvanced: keep the read, patch, write,
and readback under one queue slot, using unqueued internal read and exchange
helpers rather than calling run() inside the queued transaction. Preserve each
setter’s field-specific behavior while preventing concurrent full-row writes
from overwriting one another.

Setters that patch one field of the shared 0x00a9 advanced row read the whole row, patch it and write it back. Two such setters running at once could both read the old row, and the second write would undo the first. Hold the whole transaction under a separate row lock; the inner reads and writes still use the per-exchange queue.
