while (pXfer->SequenceTransferDescriptors(&ptd)) {
// program the h/w using  ppTD
// t << \" Physical address 0x\" << ptd->td_PhysAddr.LowPart << \". Length is 0x\"
// << ptd->td_Length << \".\" << EOL;
m_PAddr =ptd->td_PhysAddr.LowPart;
m_PAddr =ptd->td_PhysAddr.HighPart;
m_length = ptd->td_Length;
m_length = ptd->td_Length;长度只为0xfd0,为什么这么短,
怎么改变这值
而且整个传输才一段(chunks)
ULONG nTds = pXfer->GetTransferDescriptors(&ptd);

// t << \"nTds = \" << nTds  << EOL;
for (ULONG ii=0; ii < nTds; ii++)
{
m_PAddr =ptd[ii].td_PhysAddr.LowPart;
m_length = ptd[ii].td_Length;
}
ii值为0x01,怎么加大???
我渴望你的回答谢谢.
