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.

Hi Lesieur,

It may me also related to the version of USB controller divers included by Windows. You could take a look to the following links:
