Hi, dear support.
I have a problem with VBUS error Interrupt when send SCSI Inquiry Request. Inquiry Data came, but I couldn't get CSW data, 'cause have a VBUS error Interrupt.
In debugging I see that UsbInterruptHandler () is called and USB_INTRUSB_VBUSERROR_B is detected.
Your code is:
/* IF (VBUS error Interrupt) */
if ((ucIrqStatus & USB_INTRUSB_VBUSERROR_B) && pDev->Mode == MODE_OTG_HOST )
/* Acknowledge pending VBUS error interrupt */
*pUSB_INTRUSB = ucIrqStatus;
Speaking frankly, problem with DriveVbusOn. After DriveVbusOff VBUS is really off, but after DriveVbusOn VBUS is not high and power is absent on the bus. What should I do? Help me!!!
