继续USB问题

各位大哥
我现在发现一个问题
我的USB块传输管道每10ms才能读上来5个数据包（小于等于64字节）
那这样最多320/10ms的读取速度阿。怎么才能提高它呢？
我是同步读取，读到一个包就返给应用程序，应用程序记下时间。
序号秒     毫秒      收到的字节数
1   47 618 64 Receive a packet
2   47 629 64 Receive a packet
3   47 629 64 Receive a packet
4   47 629 64 Receive a packet
5   47 629 64 Receive a packet

。。。。。。
时间是在程序中GetSystenTime得到的
请各位指教！

怎么没人回答阿？

一次读多一

阿？可以一次读很多上来嘛？
我的USB设备WMaxPacketSize = 64阿
我试试看。
