where i can find the series patch?
https://patchwork.kernel.org/project/linux-usb/list/?series=427561

There is nothing at that link.

What is the lore.kernel.org link for the patch you are curious about?

when i used maiwo k1690(10gbps) connect to ASM3242 Controller, only
500MB/s.

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.

Are you sure that your hardware can really support this?  Do you have
the right cable and the device will support this speed?

maiwo k1690 connect to mainboard usb3.2 gen2x1 port can 10gbps.

pcie to usb3.2 gen2x2 asm3242 should be compatible usb3.2 gen2x1.
I don't have windows os to test them, may be 5gbps on windows yet.
Is there a way to hack them to 10Gbps on linux?

And most important, what kernel version are you using?

kernel 5.16 rc7.

thanks,
