Description:

I create an Installer USB with Arch Linux 2021.07.01. After boot into the liveUSB system, my Portable SSD cannot be detected. I create another liveUSB with Arch Linux 2021.06.01 to test. After compare dmesg with previous liveUSB (arch version 2021.07.01), I found that new kernel can detect USB 3.0 or lower device, but cannot detect USB 3.1 device.

This issue occurred on latest kernels. I'm not sure from which version on Arch, but I can confirm it on Manjaro, is from 5.4.124, 5.10.42, 5.12.9.


Additional info:

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

dmesg can found log about USB3.1 device (here is 'SuperSpeedPlus Gen 2'):
# dmesg

usb 2-4: new SuperSpeed Gen 1 USB device number 2 using xhci_hcd
usb 2-4: Product: Ultra

On Arch-2021.07.01, before run 'lsusb -v', lsusb's output:
# lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

After run the command lsusb -v, the Portable SSD can be found by command lsusb.

# dmesg
usb 2-4: new SuperSpeed Gen 1 USB device number 2 using xhci_hcd
usb 2-4: Product: Ultra
usb 2-4: Manufacturer: SanDisk

I found this problem when I upgraded Manjaro-21.0.6 (kernel 5.10.41) to Manjaro-21.0.7 (5.10.42). To confirm, I was going to install Arch and found the same problem on Arch.

Steps to reproduce:
0. plugin USB 3.1 device
1. boot into Arch-2021.07.01 liveUSB
2. run command 'lsusb'
3. run command 'lsusb -v'
