USB Hubs not recognizing all connected devices

Created: Modified: Knowledge Base

Mac

We’ve found that on newer Mac Launchpads, you may see an issue were not all connected devices via an USB hub are recognized.  This is most likely due to the Mac’s default power management settings, which limits the number of USB devices that can be connected at once. To troubleshoot this issue:

  1. Log onto you Mac as an Administrator
  2. Go to Applications/Utilities and double-click Terminal
  3. Enter the following command:
    sudo nvram usb-options="%01%00%00%00"
  4. Press Return
  5. Restart your Mac

Note: To revert this setting back to its defaults, go back to Terminal and enter :

sudo nvram -d usb-options

Press Return and restart your Mac.

Windows

Some Windows Launchpads may also experience a similar issue. This might help:

  1. Go to the Control Panel and search for Advanced System Settings
  2. Select the Hardware tab and click Device Installation Settings
  3. Select No, let me choose what to do and then click Install device driver software from Windows Update if it is not found on my computer.
  4. Click Save Changes.
