bug example

In a Windows XP system SetupDiOpenDevRegKey() returns the "Device Parameters"
HKEY under the device instance corresponding to the supplied (DeviceInfoSet,
&DeviceInfoData) pair.

Wine's SetupDiOpenDevRegKey() returns the device instance HKEY instead.

The relevant registry keys are not created by Wine, so I had to import them
from a Windows XP system

Example:

Windows HKEY returned corresponds to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\Vid_0451&Pid_6951\5&5a20206&0&1\Device
Parameters

Wine HKEY returned corresponds to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\Vid_0451&Pid_6951\5&5a20206&0&1


The attached registry patches and source code enable the reproduction of the
bug.
