One of the first (yet most often overlooked) things to try is a different USB cable, preferably one that is
known to work well. When a cable goes bad it can lead to all sorts of odd behavior (flaky connections,
dropped messages), or no behavior at all (won’t even power on)�

It’s possible that trying a different USB port on the computer may lead to a proper connection� While
extremely rare, we have come across USB ports that just don’t seem to like some USB devices�

hUB
Unpowered USB hubs may not be able to provide enough power to the K-Board Pro 4, leading to
connectivity issues� Unpowered hubs typically divide the power coming from the computer’s USB port and
split it up between all of the hub’s ports — providing less power than if the K-Board Pro 4 were to be directly
connected to the computer’s USB port� If a USB hub is absolutely necessary, it is recommended to always
use a powered hub�

hUB
If experiencing connectivity issues while using a USB hub, try without the hub and plug directly into the
computer’s USB port� The reverse holds true as well — if experiencing connectivity issues while not using a
USB hub, try with a hub (if one is available to you)�

Using the Editor you can reset the device, and all the sensors to default settings � This can sometimes help
resolve hardware quirks, or unexpected behavior�

While it is indeed possible the K-Board Pro 4 may be the source of issues, sometimes the cause is actually
due to the operating system itself� Always be aware of these issues, like the Mac OS CoreMIDI bug or the
Windows class-compliant device limitation�

If the K-Board Pro 4 is not making a connection to the computer at all (and all other troubleshooting issues
have been exhausted), it is recommended to try connecting it to a different computer� If it works on the new
computer, try the original one again� In some circumstances we have seen this solve connection issues�

We always recommend using the USB cable(s) that shipped with your K-Board Pro 4� Sadly, not all USB
cables are created equal�
If you are having troubles powering your K-Board Pro 4 or connecting to a computer, please make sure
you are using the USB cables that came with your K-Board Pro 4.
We fully understand that it seems like using different USB cables shouldn’t matter, but it really can have a
drastic effect on operation, not just with K-Board Pro 4, but with all USB devices� Very often the only thing
needed is to swap out the USB cable for another one�
