Yes. Full test matrix is in the v2 cover letter (PATCH 0/1) of this series: - DWA-X1850 A1 / B1 (RTL8852AU) - BrosTrend AX1L / AX4L (RTL8852BU) - BrosTrend AX8L / EDUP AXE5400 (RTL8852CU) Six adapters, x86_64 Tiger Lake xHCI + aarch64 BCM2712 / RP1 hosts. 60 plug-cycles + 30+ throughput cells captured 2026-04-11 to 2026-05-07. USB enumeration verified at SuperSpeed (5000 Mbps) on every patched cell. Per-cell raw evidence for the May 2026 expanded matrix (40 iperf3 JSON files per cell, byte-counter deltas, pre/post link state, pre/post USB enumeration speeds, per-iteration timestamps) at: https://github.com/Lucid-Duck/rtw89-usb3-gap/tree/main/evidence/may-2026-laptop Per-adapter summaries: https://github.com/Lucid-Duck/rtw89-usb3-gap/tree/main/adapters If the Tested-by trailer should be annotated with the specific chip list, I will add that when, and if, a v3 is needed.
