Troubleshooting Class Compliant USB Computer Peripherals
Most USB audio and MIDI computer peripherals are Class Compliant USB devices. This
means that to communicate with the computer, they use drivers that are built right into
the host computer’s operating system. These drivers are written by Microsoft (or Apple
for Macintoshes), and come pre-installed on all computers.
The advantage of Class Compliant USB devices is that they work on all modern
computers, and all modern operating systems, and will work with the next generation of
Microsoft or Apple operating systems the very same day they are released. There are no
special drivers to install, update, or configure.
With these products, we commonly receive inquiries with the following symptoms
reported:
Doesn’t connect to computer.
No Firmware installed … controller dead.
Doesn’t light up.
DOA
Based on our experience, 95% of similar inquiries can be quickly resolved and the user
gotten up and running. For the most part, similar symptom descriptions indicate
incomplete software setup, rather than a true malfunction or defect.
This means that in the vast majority of cases, a preference, setting, or option in the host
software (i.e. Ableton, Cubase, GarageBand, Pro Tools) is misconfigured. These
software programs don't configure themselves, and the user will not get any audible or
visual response from the computer or peripheral until the software is properly configured.
This guide will help determine whether difficullty is due to software settings, a hardware
defect, or other factors that can cause similar symptoms.
What does 'class compliant' mean?
A class compliant device is one that doesn't require extra drivers to connect your Windows
or Macintosh computer, or to your iPad. Class compliant devices use drivers which are
built into the host (i.e. the computer or the iPad) operating system.
To find out if your USB audio or MIDI device is class compliant, check the manufacturer's
web page. If it connects automatically to any computer without requiring you to install
drivers from a website or a disk, it is probably class compliant.

Based on our experience, over 95% of similar inquiries can be resolved and the user
gotten up and running. For the most part, similar symptom descriptions indicate
incomplete software setup, rather than a true malfunction or defect.
This means that in the vast majority of cases, a preference, setting, or option in the host

The guide below will help determine whether difficulty is due to software settings, a
hardware defect, or other factors that can cause similar symptoms.
Quick test - Windows
When you're frustrated with not being able to get up and running, or if you thinking you
might have a defective product, this 10-second is-it-broken test can restore the
confidence necessary to continue working with the product and to complete any needed
software setup or authorization process.
To verify that the device is working, and is being seen by the computer…
1. On Windows 8, 7, Vista, or XP, open the Device Manager.
2. Disconnect the controller from the computer, count to 5, then reconnect the
controller
Does the list of devices at all change, refresh, or flash? If yes…Good, the product
is recognized by the computer.
If the product does pass the test above, it is not defective, and the difficulty is caused by
misconfigured software settings or options. Carefully follow the setup instructions for the
software you are using, or contact Technical Support for assistance.
If the product does NOT pass the test above, it could be defective, or it could be that other
factors are causing the symptoms. Refer to the section below to rule out a defect or
potential other factors. This will help determine whether your symptoms are caused by
something on your computer, or by a defective product.
Quick Test - Macintosh
When you're frustrated with not being able to get up and running, or if you thinking you
might have a defective product, this 10-second is-it-broken test can restore the
confidence necessary to continue working with the product and to complete any needed
software setup or authorization process.
To verify that the device is working, and is being seen by the computer…
1. Disconnect the USB interface or controller from the computer, count to 5, then
reconnect the device.
2. In the upper-left of the screen, click the Apple Menu, and select About This Mac.
3. In the window that opens, click More Info.
4. On the next screen, click System Report.
5. A System Report window will be displayed. On the left-hand side of the window,
under Hardware, select USB.
6. Your connected USB devices will be displayed on the right (minus the device
you're testing since it is disconnected at this point in the test).
Now, connect the USB interface or controller device you are testing.
7. Once your USB device is connected, select File > Refresh Information to update
the list of connected devices.
8. You should see a new device listed once you have refreshed the list. Disconnect
the device and repeat steps 6 and 7 above if you need to confirm.
If the product does pass the test above, it is not defective, and the difficulty is caused by
misconfigured software settings or options. Carefully follow the setup instructions for the
software you are using, or contact Technical Support for assistance.
If the product does NOT pass the test above, it could be defective, or it could be that other
factors are causing the symptoms. Refer to the section below to rule out a defect or
potential other factors. This will help determine whether your symptoms are caused by
something on your computer, or by a defective product.
Other factors
Note that these factors affect all USB MIDI and Audio Devices the same regardless of the
manufacturer, and can be resolved through Technical Support:
Poor USB communication – bad port, or the use of USB Hub or USB extension
cables. This is actually quite a common issue. Perform the quick test above using
a USB different port, or on a different computer.
Bad USB cable - try a different USB cable.
Logitech Camera Driver Conflict – if you’ve ever connected one of these web-
cams to your Windows PC you’ll have trouble using USB audio or MIDI devices.
This does not affect Mac users. See below.
Missing or corrupted Windows or Mac OSX files – these class-compliant
product use drivers built in to the Windows and Mac OS. If these files are missing
or corrupted, the product won’t function as expected. We can help diagnose and
repair this symptom. Of the potential causes for difficulty descriped in this article,
this is the least likely. All other potential causes should be ruled out first. See
below.
Ruling out software setup errors versus hardware failure can be difficult. See the
Computer Peripheral Testing guide linked below. This archive includes resources
and instructions that can be used to test any class-compliant USB Audio or MIDI
computer peripheral in about 2 minutes. The guide linked below was developed to
shorten evaluation time for repair depots, service centers, and is not intended as
a self-support tool for general public. If you need asssitance with your software
settings, contact Technical Support.
Technical Support
The suggestions above should help quickly determine whether a product is functional,
and to overcome common setup obstacles such as poor USB communication. If you
require further assistance with product setup, contact Technical Support. We've included
contact links for several manufacturers below:
Akai Professional
Alesis
Alto Professional
ION Audio

Prescription Resources
The three resources below are described above. These should be considered prescription
medicine... only to be used to remedy a specific symptom. These are not general
maintenance tools. It is not recommended that you use these resources unless you are
confident you are affected by the specific scenarios that cover them above. Use these
files at your own risk. If you are uncertain whether or how you should use the resources
