USB_AUDIO_DEVICE_JF128_PEx example project results in 'USB not recognised'

[lewismarkwell]

Hi,

I am currently using the example project 'USB_AUDIO_DEVICE_JF128_PEx' provided with Freescale USB Stack v4.1.1 within Codewarrior for MCU v10.6.4.

I have encountered an issue whereby when building the project and uploading the resulting .s19 to both the TWR-MCF51JF development board and my own custom board based around the MCF51JF128  (at separate times) have resulted in the following the following message when connected to Windows 7 and 10:

"

Windows has stopped this device because it has reported problems. (Code 43)

A request for the USB device descriptor failed.

"

Is there anyone who would be able to assist in resolving this issue, therefore effectively allowing the device to operate as intended?
