usb endpoint pairing 可不可以ep2,4,6同时用？

我把an2131Q的一个例子ep_pair改为ep2,ep4,ep6同时用，可是用control panel 做bulk transfer时，只有ep6可用，为什么？

可以啊，我是过

我试了，还是不行，您帮我看看我改的对不对：
void TD_Init(void) // Called once at startup
{
// Enable endpoint 2,4,6 in, and endpoint 2,4,6out
IN07VAL = bmEP2; // Validate all EP\'s
OUT07VAL = bmEP2;
IN07VAL = bmEP4;
OUT07VAL = bmEP4;
IN07VAL = bmEP6;
OUT07VAL = bmEP6;
//Enable double buffering on endpoint 2,4,6in, and endpoint 2,4,6out
USBPAIR = 0x3F;

    //Arm Endpoint 2,4,6 out to recieve data
EPIO[OUT2BUF_ID].bytes = 0;
EPIO[OUT4BUF_ID].bytes = 0;
EPIO[OUT6BUF_ID].bytes = 0;
// Setup breakpoint to trigger on TD_Poll()
BPADDR = (WORD)TD_Poll;
USBBAV |= bmBPEN; // Enable the breakpoint
USBBAV &= ~bmBPPULSE;
}

void TD_Poll(void) // Called repeatedly while the device is idle
{
BYTE count2, count4, count6, i;

if( !(EPIO[OUT2BUF_ID].cntrl & bmEPBUSY) ) // Is there something in the OUT2BUF buffer,
if( !(EPIO[IN2BUF_ID].cntrl & bmEPBUSY) ) // Is the IN2BUF available,
{
count2 = EPIO[OUT2BUF_ID].bytes; // Then loopback the data
for(i=0;i<count2;++i)
IN2BUF = OUT2BUF;
EPIO[OUT2BUF_ID].bytes = 0;
EPIO[IN2BUF_ID].bytes = count2;
}



if( !(EPIO[OUT4BUF_ID].cntrl & bmEPBUSY) )
if( !(EPIO[IN4BUF_ID].cntrl & bmEPBUSY) )
{
count4 = EPIO[OUT4BUF_ID].bytes;
for(i=0;i<count4;++i)
IN4BUF=OUT4BUF;
EPIO[OUT4BUF_ID].bytes = 0;
EPIO[IN4BUF_ID].bytes = count4;
}

if( !(EPIO[OUT6BUF_ID].cntrl & bmEPBUSY) )
if( !(EPIO[IN6BUF_ID].cntrl & bmEPBUSY) )
{
count6 = EPIO[OUT6BUF_ID].bytes;
for(i=0;i<count6;++i)
IN6BUF=OUT6BUF;
EPIO[OUT6BUF_ID].bytes = 0;
EPIO[IN6BUF_ID].bytes = count6;
}
}


谢谢！

老大,你没写过程序啊???怎么复制语句都用的如此差???
\"IN07VAL = bmEP2; // Validate all EP\'s
OUT07VAL = bmEP2;
IN07VAL = bmEP4;
OUT07VAL = bmEP4;
IN07VAL = bmEP6;
OUT07VAL = bmEP6;
\"
这段是什么???
最后结果,只有IN07VAL = bmEP6;和OUT07VAL = bmEP6;
要势能2,4,6,应如下IN07VAL |= bmEP6+bmEP2bmEP4;
OUT 雷同
