Hi, I have the same problem. I can perfectly use this key on a usb2 port. The usb3 port is working, i can use pendrive on this port.
The outputs when the key is plugged on usb3 are: 1) dmesg [40261.131061] usb 2-1: new SuperSpeed USB device number 6 using xhci_hcd [40261.152025] usb 2-1: New USB device found, idVendor=0bda, idProduct=8153 [40261.152035] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=6 [40261.152042] usb 2-1: Product: USB 10/100/1000 LAN [40261.152048] usb 2-1: Manufacturer: Realtek [40261.152053] usb 2-1: SerialNumber: 000001000000 [40261.283522] usb 2-1: reset SuperSpeed USB device number 6 using xhci_hcd [40261.345831] r8152 2-1:1.0 eth0: v1.09.9 [40261.407779] r8152 2-1:1.0 enx9cebe85eac03: renamed from eth0 [40261.433452] IPv6: ADDRCONF(NETDEV_UP): enx9cebe85eac03: link is not ready [40261.437807] IPv6: ADDRCONF(NETDEV_UP): enx9cebe85eac03: link is not ready [40261.471953] usb 2-1: USB disconnect, device number 6 [40261.472042] r8152 2-1:1.0 enx9cebe85eac03: Stop submitting intr, status -108 2) lspci 00:00.0 Host bridge: Intel Corporation Skylake Host Bridge/DRAM Registers (rev 08) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) 00:04.0 Signal processing controller: Intel Corporation Skylake Processor Thermal Subsystem (rev 08) 00:13.0 Non-VGA unclassified device: Intel Corporation Sunrise Point-LP Integrated Sensor Hub (rev 21) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21) 00:15.0 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #0 (rev 21) 00:15.1 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #1 (rev 21) 00:16.0 Communication controller: Intel Corporation Sunrise Point-LP CSME HECI #1 (rev 21) 00:17.0 SATA controller: Intel Corporation Sunrise Point-LP SATA Controller [AHCI mode] (rev 21) 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #5 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Sunrise Point-LP LPC Controller (rev 21) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21) 00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21) 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21) 01:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) 3) lsb_release -a LSB Version: core-9.20170808ubuntu1-noarch:printing-9.20170808ubuntu1-noarch:security-9.20170808ubuntu1-noarch Distributor ID: Ubuntu Description: Ubuntu 18.04.1 LTS Release: 18.04 Codename: bionic 4) uname -a Linux xxx-inspiron 4.15.0-39-generic #42-Ubuntu SMP Tue Oct 23 15:48:01 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux 5) lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 005: ID 04f3:2494 Elan Microelectronics Corp.
