This step-by-step guide walks you through the process of enabling the USB driver for the SpeechMike, in case it goes into a strange loop that requires a rather unusual process to get the drivers to load. Illustrated screenshots have been included for your convenience.

STEP 1: Connect your SpeechMike to a USB port on your computer

Once you have connected your SpeechMike you should hear a “mee” beep as the USB driver enumerates. After this, you may see an MS Windows message that says ‘you must restart your computer to apply these changes’. Do not do this. Choose, ‘Restart Later’. Now, locate the directory that contains your firmware upgrade.

Note: When the wizard has an issue finding the device, do not fret. It happens from time to time. This is where this document comes in handy. The issue may occur if there is an interruption during the upgrade process. Click next and we will move to Step 2.

STEP 2: Attempt to Connect the Device Using the Firmware Upgrade Wizard

Disconnect your Speech Mike and hold down the two buttons on the top right of the Speech Mike. Insert the Speech Mike cord into the USB port. All buttons should light up, putting the device in upgrade mode. Now, you can release the buttons and move through the wizard. If not, there are other avenues to explore. 

STEP 3: Attempt to Connect the Device Using the Firmware Upgrade Wizard (but remains in >’Waiting to be available ….’)

If you find yourself in this waiting mode, cancel out of the Firmware Install Wizard, Driver Installation Page. Before continuing, we need to reset some things in Windows. Let’s move to Step 4.

STEP 4: Go to Device Manager and uninstall the USB driver so that you are able to start over with the Firmware Install Wizard

To go to the device manager, go to ‘My Computer, right-click, and choose Properties. Under Tasks, choose Device Manager. Once in Device Manager, look under Universal Serial Bus controllers for the TI DFU Class Driver 5. Right-click and uninstall.

STEP 5: Clean Install of TI DFU Class Driver 5 after deleting it from Device Manager

Insert the Speech Mike into the USB port and look in Device Manager for ‘Unknown’, under [Other Devices]. Right-click and select ‘Scan for hardware changes’. After that, a box will pop up prompting you to what it should do next. Choose ‘Locate and install driver software’. Browse to the location of your Firmware installation and choose the directory that contains the file, [DFUUSB.sys]

STEP 6: After the driver installs successfully from the Firmware Upgrade Wizard, you are good to go. Enjoy!

Go to your Philips Speech Exec software and start using your SpeechMike.
