Hi Varuzhan

I had the same problem where the USB would not re connect. Heres what 
I did. It is a hack but works until I have time to work it out 
properly or someone publishes the correct method.

I have set my MCB2140 as self powered for debugging ease. 

in USBCFG.h I changed some zeros ot ones like this

#define USB_POWER_EVENT     1//0
#define USB_RESET_EVENT     1
#define USB_SUSPEND_EVENT   1//0
#define USB_RESUME_EVENT    1//0
#define USB_WAKEUP_EVENT    1//0

in USBUSER.C I did this

#if USB_RESUME_EVENT
void USB_Resume_Event (void) {
  // TODO: hacky fix so reconnect works. Find out right way later
  // this fix makes self powerd devices work on reconnect
  USB_Reset();	// USB hardware reset
  USB_Init();                               /* USB Initialization */
  USB_Connect(TRUE);                        /* USB Connect */
}
#endif


Cheers
Kiwi Keith
