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).

ry plUgging inTo a differenT
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.
d
o noT Use an UnpoWered
Unpowered USB hubs may not be able to provide enough power to the BopPad, 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 BopPad 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.

ry WiTh or WiThoUT a
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).

e aWare of BUgs naTive To The operaTing sysTeM Being Used
While it is indeed possible the BopPad 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.

end The reCaliBraTion
Sending the "Reset all controllers" message (CC 121) to the BopPad on any channel will perform a short
recalibration. Sending the "All Sounds Off" message (CC 120) to the BopPad on any channel will make it
output a note off message for all notes across all quadrants.

onneCT To a differenT CoMpUTer
If the BopPad 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 BopPad. Sadly, not all USB cables are
created equal.
If you are having troubles powering your BopPad or connecting to a computer, please make sure you are
using the USB cables that came with your BopPad.
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 BopPad, but with all USB devices. We often encounter devices that
appear to not be functioning properly; very often the only thing needed is to swap out the USB cable for
another one.
