I have the same, or at least similar issue as @Adam.
I also have a Sandisk Ultra USB Flash Drive (but 64 GB). It is
recognized and mounted by the operating system when I plug it in
directly to my laptop's USB 3.0 ports. I also use a USB 3.0 4-port hub
to allow connection of mouse, keyboard, (and ideally, flash drives). The
laptop, mouse, keyboard and hub work well together. I presume mouse and
keyboard use USB 2.0.
However, when I connect the Flash Drive thru the USB hub, it isn't
recognized. See outputs of "lsusb" below.
(In fact, if I wait for 10-30min, sometimes it is recognized, suggesting
that some system event triggers recognition. I'm alerted by the
appearance of a mounted drive on the system. However, this
recognition/mounting is usually temporary.)
MY SYSTEM:
OS: Ubuntu 18.04 LTS
Linux Release: 4.15.0-33-generic
Linux Version: #36-Ubuntu SMP Wed Aug 15 16:00:05 UTC 2018
Laptop: Lenovo T580 Thinkpad (2 x USB 3.0 ports)
USB Hub: Targus ACH124 4-Port Hub (USB 3.0)
Drive: Sandisk Ultra USB Flash Drive (USB 3.0)
Note that the same hub and flash drive worked well together on an older
laptop (with USB 2.0 ports) using an older OS (Ubuntu 16.04). They also
used to work well with the current laptop and OS, but not after suspend.
I'm guessing that a kernel or OS update/patch changed this behaviour.
There seem to be several reports of drives having difficulty being recognised
under USB 3.0 protocols, suggesting the problem lies in the USB 3.0
implementation within the linux kernel. Some of these reports involve USB hubs,
for example:

https://www.reddit.com/r/archlinux/comments/678lri/usb_3_ports_no_longer_working/
Below are outputs from command "lsusb" under both scenarios. The flash
drive appears as "SanDisk Corp. Ultra". The hub appears as "Genesys
Logic, Inc. 4-port hub"

Title:
Sandisk Ultra USB 3.0 Flash Drive doesn't work in USB 3 ports
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have a 128 GB Sandisk Ultra USB Flash Drive. It works when I plug it
into a USB 2.0 port, or if I partially insert it into a USB 3.0 port
(so the USB 3 pins don't make contact).
Here's what lsusb says about it:
Bus 001 Device 005: ID 0781:5581 SanDisk Corp. Ultra
And dmesg from a successful connection:
[ 1269.667097] usb 3-1.4: new high-speed USB device number 6 using xhci_hcd

But if I insert the drive all the way into a USB 3.0 port on a hub, I
get nothing. And on a USB 3.0 port on the machine directly, I get this
in dmesg:
[ 1395.230629] xhci_hcd 0000:03:00.0: Cannot set link state.

...repeats until unplugged...
It doesn't show up in lsusb in the USB 3.0 port.
