Problem about the parameter dwFrames of issueisochtransfer

Dear all,
In the default source code, "MAXPACKETS" is set as 64. But if so, it can't work in my platform. I use WINCE5.0 EHCI driver. If I set "MAXPACKETS" as 16, it can work. Does anyone meet with this problem?

The issue may be memory consumption on some systems. I increased the buffer value to 64 to handle USB 2 transfers in CE 6. If you have a compiler and don't need USB 2 speeds, you can reduce the number of buffers.

In a future version of the driver, I'll make this settable in the registry.
