It seems to be an issue for me also. I've gone through 4 of these wonderful pieces of crap. I've had usb issues, as a keyboard connected to the usb portion will randomly fail to wake up the MacBook Pro. I have a hdmi monitor connected to it along with the charging cable. Even opening up the macbook, the USB port will not function.

Monitor also displays wonky colors and noise. If I go the bluetooth route, all functions fine, so the issue resides possibly with the adapter.
As a side note, I removed the keyboard from the adapter and connected via a usb to c plug directly and the issue is less frequent but still happens. I'm beginning to think its Sierra not playing nicely with usb-a type items. I have a usb-c gen 2 raid system set up, connected directly to a usb-c port and it wakes up and functions as it should with no issues. My son is having constant issues with usb and the adapter.

2016 13 ntb base - will not play nicely with any usb items connected via adapters 2016 13 tb - randomly drops all usb functions all the adapters have been updated. Thanks for your replies. I had some issues with installing the driver. It took several times for the driver-notification not to prompt on every reconnection of the adapter. I then followed a guide on the internet on how to install that driver correctly and it all seemed fine (accepting that the new MBP would not feed to HDMI before login - Is this normal behaviour?). Now, after the hard shutdowns I experienced, the MBP will not even boot when connected to the adapter. Could this be a driver issue?
I think that the hardware is fine; when not connected to the adapter everything works perfectly. Thanks for your replies. I had some issues with installing the driver. It took several times for the driver-notification not to prompt on every reconnection of the adapter.

This sounds crazy, but coming from a windows machine I tried the following: 1)attach everything your gonna connect to the machine 2)do a clean install of Sierra 3) if it not already done, update to the latest version I did this and my machine seems to be running ok for now. No issue, but the reinstall was a pain and took longer than it should have, but it all worked out in the end. AND NO, its not an adapter problem, as I have gone through 4 of them and still had issues.
Its more of a Sierra vs thunderbolt3 vs usb as my best guess. Also from the hard resets I've gone through, what appears to be a crash is a very very very long Sierra pause. My machine even heated up to a very nice warm feeling through the lid when closed. Support told me to hold down the power button and restart, and 2 attempts later all worked fine. Good luck, as apple was no help to be honest, as I seem to be the only one to have issues according to them. My son has an engineering case open with similar issues, but they keep pushing it off. So time will tell.
As another note, try to ditch the av adapter over time. I forget what model you have, but I have the tb version and have gone to 4 connections, with a usb-c to hdmi on order, a usb-c to usb-a, power cord to charge and my raid usb-c gen 2 to usb-c gen2. There is a 5 port powered usb-c 3.0 hub attached to the usb-c to usb-a cable. So, 4 cables is worse than 1 but better than my windows machine.
