Summary

Added explicit support for these pulsar mice

• Crazylight 8k Dongle (0x3710:0x5406)
  • X3 Crazylight Mini
  • Xlite Crazylight Mini
• Zywoo the Chosen X (0x3710:0x7401)

Theoretical support (needs testing) for any other mice using the Crazylight 8k Dongle. (Found using Pulsar's korean product listings)

• X2 CrazyLight Mini
• X2H CrazyLight Mini
• X2N CrazyLight
• X2N CrazyLight Mini
• Xlite Crazylight
• X3 CrazyLight Mini
• X3 CrazyLight
• X3 LHD CrazyLight Mini
• X3 LHD CrazyLight
• Pulsar Lab X2F

Fixed + adjusted Pulsar Pro Dongle Report Length to 64 bytes from 63 bytes

Details

Added Crazylight 8k Dongle PID to detection 0x5406
Added CID + MID name identification for 107 unique mice using Pulsar's Bibimbap web application JSON list.

After adding the Crazylight 8k dongle PID, the following mice were automatically picked up by PulsarHidClient as they use Pulsar’s report-8 configuration protocol even without adding explicit PID whitelisting

• X3 Crazylight Mini (0x3710:0x3507)
• Xlite Crazylight Mini (0x3710:0x3506)

Extrapolating on this, all mice using PCL8KDG01 (Pulsar Wireless CrazyLight 8K Dongle) should be auto-detected by the PulsarHidClient, given X2 Crazylight support is already in the repo.

Protocol Changes:

For the Pro adapter protocol

• The wired Zywoo mouse lacks HID report descriptors, so detection has been updated to allow known wired product IDs and an input/output report-0 pairs without requiring the adapter’s usage page and usage.
• Function to let Pulsar pro support for switching DPI stages and changing the DPI of a stage have been added.
• Corrects the shared Pro report length from 63 to 64 bytes. Wired and wireless captures both show 64-byte transfers with identical DPI-stage and polling writes.

Features Supported

• All existing protocol features are supported.
• Pulsar pro support for DPI stage switching and DPI stage DPI changing

Testing and Evidence

• USBPcap + Wireshark captures and testing and verification on hardware.

Not supported

• All features not already implemented in protocol handler

Summary by CodeRabbit

• New Features
  • Added recognition and status reporting for additional Pulsar models, including the CrazyLight 8K Dongle.
  • Added support for wired Pulsar Pro devices, with wired connection details and polling rates up to 8 kHz.
  • Added controls for editing DPI values by stage and selecting an active DPI stage.
• Bug Fixes
  • Improved fallback naming for unknown or incomplete device identifiers.
  • Improved handling of invalid DPI settings and stage configurations.

Walkthrough

Pulsar status reporting now resolves model names from CID/MID identifiers and recognizes an additional XS1 receiver. Pulsar Pro support includes wired devices, updated status and polling metadata, and validated DPI stage selection and editing.

Changes: Pulsar device identification

Layer / File(s)	Summary
CID/MID model-name resolution src/drivers/pulsar/model-names.ts, src/drivers/pulsar/pulsar-hid.ts, src/drivers/pulsar/pulsar-hid.test.ts	A CID/MID map supplies names for Pulsar-vendor devices. Status reporting retains product-name and generic fallbacks. Tests cover mapped names and fallback cases.
XS1 receiver recognition and polling src/pulsar/index.ts, src/drivers/pulsar/pulsar-xs1-hid.ts, src/drivers/pulsar/pulsar-xs1-hid.test.ts	Product ID 0x5406 is added to the XS1 product sets and maps to the Pulsar CrazyLight 8K Dongle name. Its maximum polling rate is set to 8000 Hz. Tests cover naming and polling-rate metadata.

Pulsar Pro wired support and DPI controls

Layer / File(s)	Summary
Wired Pro recognition and status src/pulsar/index.ts, src/drivers/pulsar/pulsar-pro-hid.ts, src/drivers/pulsar/pulsar-pro-hid.test.ts, src/drivers/registry.test.ts	Pulsar Pro product IDs and report length are updated. Wired devices receive wired connection details and polling-rate metadata, and skip receiver-only queries and save-allow commands. Tests cover client selection, polling, and status behavior.
Validated DPI stage controls src/drivers/pulsar/pulsar-pro-hid.ts, src/drivers/pulsar/pulsar-pro-hid.test.ts	DPI setters validate the reported stage configuration and verify write readbacks. Tests cover stage selection, valid edits, invalid inputs, malformed configurations, and mismatched readbacks.

Merge Risk: Low · previous review aff9c

Editing DPI stages while another DPI change is still in flight could silently undo one of the edits on Pulsar Pro mice. This is a narrow edge case that the user can fix by re-applying the setting. Wired Pulsar Pro support and the CrazyLight dongle support otherwise look mergeable, but the lost-update behavior is worth fixing or accepting explicitly.

Full details: Title check

Explanation

The title names the main change: adding support for the Pulsar Zywoo the Chosen X and mice using the Crazylight 8K Dongle. The changeset adds wired Zywoo product ID 0x7401, the CrazyLight 8K Dongle PID 0x5406, a model-name map for CID/MID pairs, and Pro DPI stage controls. The title is long (102 characters) and does not mention the model-name map or DPI changes, but it is related to the primary change and is not vague or off-topic.

devices report only mouse firmware and omit the dongle firmware entry; retain
both firmware entries for wireless devices.
- Line 47: Update the supported-product gate for Pro client selection to accept
a device whose product ID is in either PULSAR_PRO_PRODUCT_IDS or
PULSAR_PRO_WIRED_PRODUCT_IDS, while preserving the existing wired report-pair
check.
- Line 168: Update readStatus() to expose the enabled DPI stage values and
active stage index in the status metadata, and include ui.dpiStageEditor so
OpenMouse can use the shared stage editor. Preserve the existing wired UI hints
and keep stage-count editing disabled.

- Line 141: Update PulsarXs1HidClient.readDeviceInfo() so product ID 0x5406
receives the same 8000 Hz polling ceiling as 0x5403. Preserve the existing
polling-rate validation in readStatus() so decoded rates up to 8000 Hz remain
supported for 0x5406.

Major · Data Integrity & Integration · Quick win

Serialize each Pulsar Pro DPI read-modify-write operation.

setDpiStageValue() and setActiveDpiStage() each read the complete DPI table before they write. Each write sends a full table snapshot. If two of these calls overlap, the later write can restore stale values and discard the earlier edit. For example, a concurrent setActiveDpiStage() can restore the old value of a stage edited by setDpiStageValue(). The commandQueue serializes each command, but it does not protect the read, write, and readback sequence of a setter. The readback in setActiveDpiStage() checks only the active stage, so it does not detect the lost stage value.

Serialize the complete DPI operation with a separate lock, and do not reuse commandQueue for that lock. The setter's nested command() calls already wait on commandQueue. A whole-operation lock on that same queue would wait on itself.
