where i can find the series patch? https://patchwork.kernel.org/project/linux-usb/list/?series=427561
when i used maiwo k1690(10gbps) connect to ASM3242 Controller, only 500MB/s.
cat /sys/devices/pci0000:00/0000:00:01.3/0000:09:00.0/usb3/speed, 480
cat /sys/devices/pci0000:00/0000:00:01.3/0000:09:00.0/usb4/speed, 20000
maiwo k1690 is on /sys/devices/pci0000:00/0000:00:01.3/0000:09:00.0/usb4/4-1.
cat /sys/devices/pci0000:00/0000:00:01.3/0000:09:00.0/usb4/4-1/speed, 5000

i don't have NVMe to USB 2x2 Enclosure (ASM2364 chipset), i have NVMe to USB 2x1 Enclosure (RTL9120B chipset), maiwo k1690, using it on PciExpress X4 add in card (ASM3242 chipset), it only 5Gbps speed, should be 10Gbps.
