The HIDMaestro v1.6.1 USB DualSense profiles (dualsense and dualsense-composite) lack alwaysArmed, so the vendor-blob encoder never runs and the Sony tail of report 0x01 remains zeroed. Raw consumers decode byte 33 == 0x00 as a permanently down touch contact at (0,0), which Windows Precision Touchpad interprets as a held drag (causing menus to auto-focus and inertia-scroll). Fix: - Embed patched profiles with extendedReport.alwaysArmed = true. - Load patched profiles before the stock catalog (first registration wins). - Populate raw IMU fields in SubmitMotion so the codec encodes actual sensor values (accel = g × 8192, gyro = dps × 16 per SDL hidapi_ps5). - Emit an idle frame immediately in ControllerSession.ctor to eliminate the zeroed report window between device creation and the first client input. Resolves the stuck touchpoint at (0,0) and the associated PTP-driven menu scrolling.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to If the patched DualSense profiles fail to load, the sidecar can still start with a default profile and the phantom touchpoint may return, causing unwanted Windows focus or scrolling. Merge should wait for profile-loading failure to stop initialization or for that risk to be explicitly accepted. Sequence Diagram(s)sequenceDiagram

修补配置加载失败时必须中止初始化。
LoadPatchedProfiles() 捕获异常后继续执行。随后 Line 24 会加载未修补的默认配置。Attach() 仍会找到同名 profile，但该 profile 不保证 alwaysArmed，因此会静默恢复 (0,0) 幻影触摸问题。
当注册数量少于两个或资源加载失败时，记录错误后抛出异常。不要继续启动 sidecar。
建议修改
- if (_context.LoadProfilesFromDirectory(directory) < 2)
- Console.Error.WriteLine("Patched DualSense profiles did not fully register");
+ if (_context.LoadProfilesFromDirectory(directory) < 2)

}
catch (Exception error)

Console.Error.WriteLine($"Unable to load patched DualSense profiles: {error.Message}");

问题
虚拟 DS5 手柄在测试软件（ControllerMeta）中显示触摸板左上角常驻触点 (0,0)，Windows 菜单出现自动聚焦和惯性滚动。
根因
HIDMaestro v1.6.1 的 USB DualSense profiles (
dualsense/dualsense-composite) 缺少alwaysArmed标志，导致 vendor-blob 编码器永不执行，报告 0x01 的 Sony 私有区（字节 7 滚动计数、8-10 按键、16-28 传感器、33-40 触摸、53 电量）保持全零。字节 33 = 0x00 被所有 raw 消费者解析为"触摸中，id 0，坐标 (0,0)"，Windows Precision Touchpad 将其视为持续按压拖拽。真实 USB DS5 从开机就直出完整 64 字节 0x01 报文，alwaysArmed正是匹配硬件行为的配置。修复
dualsense.json/dualsense-composite.json），添加extendedReport.alwaysArmed: trueSidecarServer启动时先加载 patched profile（重复 ID 跳过，先注册者胜），再加载默认 catalogSubmitMotion补写 raw IMU 字段（AccelX=g×8192,GyroPitch/Yaw/Roll=dps×16，换算常量来自 SDL hidapi_ps5，轴 1:1 映射），否则武装后体感归零ControllerSession构造函数末尾立即提交一帧居中空闲态，消除设备创建到首帧输入间的全零报告窗口验证
