So the situation: there is a motherboard without 3.0 ports. A PCI-E card for 6 usb ports 2-3 (automatic selection) was purchased with add. power (connected).

The system sees it lspci:

02:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller (rev 03)

Googled about it, a chip like NECovsky. On the NEC website in the firewood section is:

The USB driver is released from the Linux community site. It is included in Linux kernel. Download the Linux Kernel from the Linux community site, if you are using the Linux driver. Please contact the Linux community if you have a question regarding the Linux driver.

Supposedly there is support in the core. Ok, I turn on the module: # modprobe xhci_hcd The system starts to see and work perfectly with everything that is plugged into the board, but suspiciously slowly (there is an external screw, it works with the same ridiculous speed as before).

Judging by 2.1 and a speed of 480 mbs (corresponds to 2.0), the hardware stubbornly does not want to use its full potential. About $ uname -a

  • 1. you have twice the output of the same command lsusb -v -s 2:3 . 2. Complete the picture for completeness with sudo hdparm -t /dev/устройство output and dd if=/dev/zero of=/новый/файл/на/примонтированном/устройстве/который/потом/можно/удалить bs=1G count=1 - aleksandr barakin

  • Yes, the speed is too small. but, quite possibly, the “bottleneck” in your case is not the usb interface, but the pci-e interface. I just remembered how about three years ago I was dealing with low wifi performance in some model of the router. The adapter was connected via the pci-e bus. so the guys from the openwrt website helped - they found problems in the driver of the bus. whether it was in the algorithm, or in the timings - I don’t remember. It is not excluded that you have a similar problem. or maybe some parameters are needed for the code implementing the bus communication. look this way. - aleksandr barakin
  • Considering that for some reason the devices are switched on in the 2.0 mode, I will assume that this is not the bus. it’s not just a question of speed, I’m not measuring it, since it depends on a lot, but on the usb port mode that is clearly prescribed - Alex Melnikov
  • included in the 2.0 mode - here you know better. I did not see usb3 devices in my eyes (controllers, that is), and I’m not guided that lsusb and others should show about them. - aleksandr barakin

the problem is solved by changing the kernel and switching to mint
