Kamvas 13 Keeps Disconnecting and Reconnecting

Steven Lewis

started a topic over 2 years ago

Hey there! Recently bought the Kamvas 13 from Amazon and immediately fell in love with it but recently its been having issues staying connected. I'm using the 3-1 cable and it will start a cycle of disconnecting and reconnecting. The screen will stay on but the led light will be constantly turning off then on with the windows noise signaling a device being disconnected. I've tried updating the driver (none available), reinstalling the driver, unplugging the tablet and plugging it back in but it always ends up doing this. Is this a driver issue? Cable issue? Bad tablet?

Hi Steven Lewis, there are several possible causes of your issue; the 3-in-1 cable, not enough power supplied to your tablet, your computer's USB port, your tablet's USB-C port, or your tablet's internal board itself. Kindly answer the following questions to have a better idea on what may have caused it:
1. Does the tablet driver continue to show "Device connected" when the cycle of disconnecting and reconnecting is happening?
2. How about the screen; does it flash as well or is it just the tablet's LED light that is affected?
3. When you plugged your tablet back to your computer, have you tried plugging it to another USB port?
4. Have you tried connecting your tablet to another computer, if you have access to another unit? If you have, do you encounter the same issue?
5. Is the red USB end of your 3-in-1 cable connected directly to a power outlet?
Here's an article about the Kamvas 13 connection that may help: How do I connect the Huion Kamvas 13 to my computer?

I have the exact same issue (Windows 10, Kamvas 13, 3-in-1 cable). Please let me know if you find a solution.

I have tried:
Firmware and Driver update
Different USB ports on motherboard
Pugging in the red USB power (same result plugged in or not)
Different USB ports on a PCI Express expansion card
Changing Windows and BIOS USB power settings.

I suspect some sort of driver (power/time out) issue.

Hi! I have the exact same problem with my Kamvas 13 2020 version. I'll go ahead and answer the questions as they pertain to me:

1- The tablet driver shows the tablet disconnecting and reconnecting, not remaining connected

2- The screen stays turned on, no flashing or anything

3- Yes

4- No I only have one

5- Yes it's connected to a phone charger: Input 100 - 240V-50/60Hz, 0,35A Output: 5V = 2A

Have the same exact problem, keep disconnected & reconnect at random time. (sometimes its just once every few hours, sometimes its 2-5 times rapidly)

display stay active when its disconnected, power led blink & driver icon turn grey. when its reconnected, the pen works fine & pressure still there.

i have tried everything, uninstall & reinstall, use older driver version, disable usb power saving, delete wintab32, reinstall drive, disable device power saving, clean registry, wipe all ghost drives... anything that i can think of & find on internet and its still f happening.

its definitely not cable problem too, because i have tried shaking it & wiggle the port but the disconnection is not triggered.

I have replied to the troubleshooting steps in my ticket but I'll add the info here too for the reference of others with this issue:

Have you plugged the red USB cable into a power supply
Yes. An Amazon 5W AC Adapter Output 5.0V 1.0A

1) Please make sure that the USB cable is connected securely, and the USB port is functional;
Yes. All cables are secure (moving cables does not cause disconnect). The tablet functions normally apart from the disconnecting cycle.

2) Change to a different USB port;
I have tried multiple ports on the motherboard (ASUS Prime X570-PRO). I have also installed a separate PCI-E USB Card (Inatek 4 port PCI-E card) with its own drivers and tried the ports on that.

3) Change to a different computer;

I have not tried this yet, but I see from your support pages that others are having the same issues

4) A video that can show the problem clearly;(upload to Dropbox or Google Drive would be preferred)；
Video of issue and showing red USB plugged into power supply:

I've supplied a video to support, but I don't think the comments section here will allow links.

BTW Ivandi, my issue is exactly the same: It keeps disconnecting & reconnect at random time. (sometimes its just once every few hours, sometimes its 2-5 times rapidly). I had to be ready with my phone to get a video as soon as I hear "the bings"

So... I got a response from Huion support. They want to send me a new 3-in-one cable BUT I have to pay £20 shipping (for the £35 cable) ...

I asked why they think it's the cable that's the issue, but they just repeated that the cable is "broken".

I'm not completely convinced the cable is the issue as the disconnects happen even when there is no movement of the cable or Kamvas 13. On top of that, it would be a coincidence that we ALL have "broken" cables that do the exact same thing.

I also found this reddit post with more users with the same thing:
https://www.reddit.com/r/huion/comments/jy2dxd/green_light_flickers_on_and_off_on_kamvas_13/

Some suggest it could be a Driver/Win 10 problem (which seems more likely to me)

So before paying to ship a new cable I'm testing my tablet on a different Win10 PC with a fresh install of the latest driver to see if that helps. So far 1 hour without disconnects, but I'll leave it on for a whole day and see if it does the same thing.
