UFI协议中，READ_10指令请求的数据怎么写

Question

根据UFI协议指令，READ_10指令发来后，我们怎么处理，数据该怎么返回？
我返回的数据是这么做的

readBuf[0] = (32767>>24)&0xff;
readBuf[1] = (32767>>16)&0xff;
readBuf[2] = (32767>>8)&0xff;
readBuf[3] = (32767>>0)&0xff;
readBuf[4] = (512>>24)&0xff;
readBuf[5] = (512>>16)&0xff;
readBuf[6] = (512>>8)&0xff;
readBuf[7] = (512>>0)&0xff;

但是我在打印READ_10，发来的数据包中，看到LBA，和CONUT这两个数据，我不知道怎么去理解这两个数据，需要我怎么返回？
上面的32767是我自己随便写的，我是想用Mass storage做个免驱设备；

READ_FORMAT_CAPACITIES数据如下：

readFormatCapacities[0] = 0x00;
readFormatCapacities[0] = 0x00;
readFormatCapacities[0] = 0x00;
readFormatCapacities[0] = 0x08;
readFormatCapacities[0] = (32768>>24)&0xff;
readFormatCapacities[0] = (32768>>16)&0xff;
readFormatCapacities[0] = (32768>>8)&0xff;
readFormatCapacities[0] = (32768>>0)&0xff;
readFormatCapacities[0] = 0x02;
readFormatCapacities[0] = (512>>24)&0xff;
readFormatCapacities[0] = (512>>24)&0xff;
readFormatCapacities[0] = (512>>24)&0xff;

READ_CAPACITY数据如下：

readBuf[0] = (32767>>24)&0xff;
readBuf[1] = (32767>>16)&0xff;
readBuf[2] = (32767>>8)&0xff;
readBuf[3] = (32767>>0)&0xff;
readBuf[4] = (512>>24)&0xff;
readBuf[5] = (512>>16)&0xff;
readBuf[6] = (512>>8)&0xff;
readBuf[7] = (512>>0)&0xff;

我现在遇到的问题是我在windows和android4.4上，使用getDeviceList可以获取到设备里面有设备，但是在Android6以上获取设备列表里面没有设备，请问各位我应该怎么配置这些返回数据？我觉得不是权限问题，我用U盘测试过，U盘可以获取到设备列表里面
