LPC214x USB problem with sleep mode

I'm working with the MCU LPC214x (LPC2141) with Windows 7, 64 bit.

 

I use a usb driver on the MCU and the usb driver lpc-ucom-vcom.inf provide by NXP for windows 7.

 

I have a problem with the sleep mode. When the microcontroller is connected by USB with the computer and the computer goes to sleep,
I have this error (BUGCODE_USB_DRIVER, 0X000000FE (0x04,0xFFFFFA8016F19010,0xFFFFFA801888600,0x0FFFFFA801AD92950)

 

 

 

 

 

 

 

 

 


The proporties of the usb driver on the MCU are :


Power management features:
00000019
PDCAP_D0_SUPPORTED
PDCAP_D3_SUPPORTED
PDCAP_WAKE_FROM_D0_SUPPORTED


I think the problem comes from the usb driver on the MCU.

 

I would like to know if the problem comes from the driver on the mcu or on windows.

 
Thanks in advance.


Best regards.
