I have a Dell Dock WD15
connected through a USB Type-C port which supports USB 3.1 & Thunderbolt 3. My computer is an Alienware 13 R3. I am running Ubuntu 16.10.
I connect my monitor through the DisplayPort on the WD15. My keyboard and mouse is connect to the USB ports on the WD15. I also use the ethernet port on the WD15 for Internet.
I usually connect the laptop to the WD15 each morning. This functions intermittently. Sometimes it works all day with no problems. Other times it fails after a few minutes.
The problem is that I lose keyboard, mouse, and network through the Dock. The video through the DisplayPort continues to function. I have to continue with the Keyboard and mouse built into the laptop.
Unplugging the WD15 from the USB Type-C port usually does not fix the problem. Most of the time a reboot fixes the problem but not always. Sometimes I have to reboot a few times. But the problem can come back in a few minutes or 30 minutes later or sometimes I don't have a problem all day.
I dual boot with Windows 10. I have the same problem with Windows10. But I don't use Windows much and I have not installed the latest Thunderbolt 3 drivers from Dell for my computer. I did a fresh install of Windows 10 and so I far just use the default drivers.
It's possible my problem is a hardware one and I have a defective Thunderbolt port (I got this computer recently). But I would like to try and diagnosis the problem. My skills with debugging hardware are not strong. I would like to know how I can try and discover what the problem is. For example what log files to look at. I have looked at
dmesg
and it appears to show something about a USB dock failing but that's as far as I have gone.Can you explain what my problem might be and/or how I can diagnosis the problem?

For sure you need to install the latest Alienware 13R3 drivers. Especially flashing the BIOS and Thunderbolt 3. I think there about 10 drivers in total that will be out-of-date from a fresh Windows 10 install.
Secondly, read this ArchLinux setup for Alienware 13 lights and what not.
Thirdly, read this ArchLinux setup for Dell XP13 (9350) which shares the same Thunderbolt technology with Alienware. There is good information for updating Thunderbolt 3.
Unfortunately the TBT3 hotplug fix available since Kernel 4.7 hasn't been compiled into Ubuntu Mainline Kernels (as of 4.14.4). You could compile your own kernel with
CONFIG_PCI_HOTPLUG=y
.Dell is now allowing you to update Thunderbolt 3 NVM in Linux starting with Kernel 4.13 and getting even better in Kernel 4.15.
Lastly, I noticed many good comments that couldn't be posted as answers because your question has been protected by the community.

TL;DR:
For some reason hot plugging my Thunderbolt dock is not working correctly on my new laptop. I am trying to determine if I've overlooked a troubleshooting step.
Problem:
If the dock is unplugged after the system has already booted then my USB devices (mouse & keyboard) will not reconnect when the dock is reconnected. Thunderbolt monitor reconnects, but not USB. No power is provided to the keyboard or mouse - keyboard lights do not illuminate & optical sensor on the mouse stays dark. This is resolved with a reboot, but the problem persists.
Hardware / Software:
- Dell Precision M3800
- BIOS A09 (previously upgraded to A10 before motherboard replacement)
- Windows 10 (direct upgrade from Windows 7 64 Bit Professional )
- Belkin Thunderbolt 2 Express Dock HD
- Thunderbolt (TM) Controller - 157D
- Device manager hardware ID 'PCIVEN_8086&DEV_157D&SUBSYS_11112222&REV_00'
- This is an Intel hardware ID (fitting as Intel makes Thunderbolt)
- GRUB bootloader
- Kali Linux on second hard drive partition
Attempted fixes: (None of these solved the problem)
- All Intel Chipset drivers reinstalled from Dell's website via their tech support's recommendation
- Driver update on Thunderbolt controller yields 'Software for your device is up to date'
- 'Fresco logic USB3.0 host controller' reinstalled
- Upgraded original OS from Windows 7 to Windows 10
- Upgraded system BIOS from A09 to A10
- Had Belkin directly replace the docking station with a new one
- Had Dell directly replace the system motherboard
- The new board has the A09 BIOS
- Stopped and started Thunderbolt (TM) service
- Booted into Safe mode
- Thunderbolt works on boot but the thunderbolt service cannot run in safe mode
- Hot plugging fails to work correctly in safe mode
- All Thunderbolt devices involved have been authorized in the 'Thunderbolt TM Software' and set to 'Always Connect'
Other Notes:
- An identical Precision M3800 and Belkin dock were ordered at the same time as my own
- This other laptop does not have the same problems mine does with hot plugging
- This other 'working' laptop has been used with both docks w/o problems hot plugging
- The 'non-working' laptop has the same problems hot plugging with both docks
- The working laptop has Windows 10 loaded onto it - it was also upgraded from x64 7 Pro
- The working laptop does not have GRUB or a second OS installed
- Cannot locate drivers for the 'Thunderbolt 157D controller' on Intel's website.
- It is possible that this is a rebadged controller they are already manufacturing; complete dearth of information.
Last Thoughts:
- Is there anything obvious I am overlooking?
- Is there some problem with hot plugging when GRUB is installed or a second OS is on a system?
- Are there any pieces of system software that typically interfere with hot plugging thunderbolt devices?
- With this description would a fresh OS reinstall likely fix the issue?
Apologies for the length of this post; thus far commercial tech support has been limited and time consuming. I am hopeful that someone in the community may already be familiar with this issue.

This is barely an answer, but re-imaging the system with a working OS fixed the problem. I have no idea what the ultimate problem was, but clearly it was something to do with software. After the re-image I also reinstalled GRUB and the second operating system. This did not prevent hotplugging from working.

Exact same issue symptoms here except that I am still hanging on to Windows 7. What I did was:
- Disconnect the device from the computer
- Go into the
device manager
- Go to the
properties
of the affected device, - Look under the
Driver
tab and - Note the
Driver Version
, then - Look under the the
Details tab
and - Get its
Device class GUID
, let's call this{XXXXXXXXXXX}
, then - Go to your registry editor
Start->regedt32
, - Back up the registry in case you mess something up.
- Look under
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{XXXXXXXXXXX}
- Find each item in there that refers to the same device (I did this by driver version) and delete its folder within
{XXXXXXXXXXX}
. - Reboot
That seemed to work for me.
