Windows 7 WinUSB driver issue

[ali]

all:
What will I do for Windows7

Does an "Unknown device" appear under "Other Devices" on Device Manager, while the device plugs in to the PC?
Apply the INF file, distributed with her WinUSB host examples, to this "Unknown device".

No, when I plug my device in, the PC lists my device among "unspecified" devices and named as "WinUSB Demo".  When I reinstall the driver, "Code18" error appears.

Check SetupAPI.dev.log under \Windows\inf folder, if it would have more clue than just Code 18.
