USB 3 not working in Debian

bubbagump · 03-06-2021, 04:15 PM

No matter what I do can't get my drives working at USB3 speeds. Everything looks right, so I am hoping some other eyes can give me some hints.

Code:

 # lsusb
    Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
    Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 001 Device 004: ID 1058:25a3 Western Digital Technologies, Inc. Elements Desktop (WDBWLG)
    Bus 001 Device 003: ID 04e8:61f5 Samsung Electronics Co., Ltd Portable SSD T5
    Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
    Bus 002 Device 002: ID 1a2c:4324 China Resource Semico Co., Ltd 
    Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It shows the USB 3.0 hub

Code:

 # lsusb -t
    /:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M
        |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M

            |__ Port 4: Dev 4, If 0, Class=Mass Storage, Driver=usb-storage, 480M

dmesg shows me

Code:

Finally lsusb -D

I have tried plugging in every port and I only get USB2. What am I missing? Jumpers? The controller is there but some option is not enabled? I'm baffled. This is Debian 10 (Proxmox technically) on the stable branch updated to latest/greatest. Thanks all!

My understanding..
The external (USB)SSD is USB3 specification https://www.samsung.com/semiconducto...v01_German.pdf
The PC connection is USB3.0
according samsung manual, uas (or uasp) should be loaded.

Quote:

usb-devices | awk -v RS="\n\n" '/04e8/'

should show "Driver=uas" Is this the case?

Quote:

lsmod | grep uas

should show it exist

lsusb -t output shows USB3 hub on bus 03 but you drives are attached to bus 01, so you do have USB3, you just haven't found it yet. Keep on looking. Consult you mobo manual, locate USB3 connector and make sure there is a cable attached to it leading to USB3 port on the case.

This is hugely useful. I wasn’t sure if the bus ID was a physical thing or a wired in parallel logical thing and who ever negotiated the connection took over.

All ports are soldered to the board, so I’m going to guess this is a dip switch/jumper/BIOS thing I haven’t found yet. At least I know it’s not a software deal and I can focus elsewhere. Thanks!
