Hi Eddie,
Thanks, it works now after increasing the reserved memory size.
But the mouse and keyboard didn't work.
The log is:

Hi,
You may have to increase the size of the reserved memory. I believe I
bumped ours up to 0x04000000.
If you use the latest version of the driver it will initially allocate
the largest buffer for size detection, but then will free unnecessary
memory once the size is detected. That may help you.
Thanks,
Eddie
