Hi Rishabh,

I tested v5 on an ASRock X670E Taichi (Ryzen 9 7950X,
BIOS 4.43) with two AMD xHCI controllers (1022:43f7).

Previously, both controllers consistently reported USBSTS
0x401 on S3 resume. With v5 applied to 7.2.11-1-cachyos,
neither controller reported this error across four
consecutive S3 cycles.

Resume also feels noticeably smoother.
