The 3810 and 3811 sticks both came with two-piece usb cable, one part is the long-range receiver that the wifi remote and internet communicate with, the second part of the cable is usb extender. A standard usb cable will power the Stick, but no remote or internet will work without that cable.
The newer 3820 and 3821 4k Streamer Sticks come with similar cable, except its a one piece, and uses micro-usb end instead of the mini-b usb your stick uses.
Sorry, I just updated my messages. I do have that extra piece. Neither the voice pro or regular voice remotes will pair with my reset roku. Attached is a picture of my TV screen.
Ok I got the Pro remote to work. I was on customer support chat and am writing down what worked finally:
1. Unplug the Roku streaming stick+ 3811X from the HDMI port
2. Unplug the power cord from the streaming stick
3. Re-plug in the streaming stick to ANOTHER HDMI port (mine was just right below)
4. Go to my TV remote and press the input button to change to the right input
5. Wait until the Roku appeared on and then on my Voice Remote Pro I held down the pair button for 5 seconds
Then it worked! So it seems that the customer support person on the phone was wrong that the Pro remote doesn't work with the 3811X. Now I have a Voice remote to return... ugh.
I spoke too soon: the Pro remote has somehow unpaired. It will work with my TV (change the volume, etc) but it won't scroll up and down the Roku Home menu. This happened the other day too.
Thanks for the post.
If you are still experiencing an issue with pairing your Voice Remote Pro, can you please provide us with the serial number/device ID of the Roku device that you are trying to pair the remote with?
Thanks for following up. I've created my own post here with a detailed accounting of all the issues and what I've done to try fix them here: https://community.roku.com/t5/Wi-Fi-connectivity/Roku-Streaming-Stick-and-Voice-Remote-Pro-Issues/m-....
I will update that post with the serial number
I have 2 enhanced remotes to replace the remote the dog ate. Neither will pair successfully...!!?? Seems to pair then gets stuck at language selection screen, NO BUTTONS WORK.
Thanks for the posts.
