I use lpcusblib debugging usbhost found that the program will stop in the WaitForTransferComplete

In enumdevice get devicedescription stop waitTransferComlete

static HCD_STATUS WaitForTransferComplete(uint8_t EdIdx)
{
#ifndef __TEST__ //
while ( HcdED(EdIdx)->status == HCD_STATUS_TRANSFER_QUEUED ) {} //while in this
return (HCD_STATUS) HcdED(EdIdx)->status;
#else
return HCD_STATUS_OK;
#endif
}

Hi Chao Li,

I would recommend you to first try modifying the lpcusblib_MassStorageHost example of lpcopen for lpc1788 and test it on an evaluation board. Please make sure you are implementing the changes described on this thread:
