Hello,

i try 3 different usb sticks and one sdcard reader at usb2.0,3.0 and 3.1.

dmesg display something but i don't show up in fdisk.

Code:
[So Jul  8 21:35:35 2018] usb 3-2: new high-speed USB device number 3 using xhci_hcd
[So Jul  8 21:35:35 2018] usb 3-2: New USB device found, idVendor=X, idProduct=X, bcdDevice= 1.00
[So Jul  8 21:35:35 2018] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[So Jul  8 21:35:35 2018] usb 3-2: Product: DataTraveler 2.0
[So Jul  8 21:35:35 2018] usb 3-2: Manufacturer: Kingston
[So Jul  8 21:35:35 2018] usb 3-2: SerialNumber: X


xHCI and EHCI are enable in kernel (gentoo-sources-4.17.4) also the filesystem vfat/msdos/ntfs.

Lately i changed my fstab with "nodev" i try to edit it and boot without nodev. it doesn't solve the problem.


Code:
/dev/sda2       /boot           ext4            noauto,noatime                          1 2
/dev/sda3       /               ext4            noatime,errors=remount-ro               0 1
/dev/sda4       /var            ext4            noatime,nodev,nosuid,noexec             0 2
/dev/sda5       /usr            ext4            rw,noatime,nodev                        0 2
#/dev/sda6      /home           ext4            noatime,nodev,nosuid,noexec             0 2
none            /tmp            tmpfs           rw,noatime,nosuid,noexec,nodev          0 0
none            /var/tmp        tmpfs           rw,noatime,nosuid,nodev                 0 0
none            /var/tmp/portage        tmpfs           rw,noatime,nosuid,nodev,mode=755,uid=portage,gid=portage,x-mount.mkdir=775      0 0

Did you forget to enable the usb-storage driver?

USB 3 can support USB attached SCSI but it needs UAS aware storage devices too.
If its in your kernel and supported by youur hardware, it will be used.
Its very little extra to add to your kernel.
