SetupDiEnumDeviceInterfaces fails on WinPE2.0

NTDEV
1

Dear Sir,
I can use following function to get correct battery information on WindowsXP or Vista, but I can’t run it on WinPE2.0.
SetupDiEnumDeviceInterfaces() always returns FALSE. GetLastError() returns ERROR_NO_MORE_ITEMS.

HDEVINFO hDevInfo = SetupDiGetClassDevs(&GUID_DEVICE_BATTERY, 0, 0, DIGCF_PRESENT | DIGCF_DEVICEINTERFACE);
DeviceInterfaceData.cbSize = sizeof(SP_DEVICE_INTERFACE_DATA); SetupDiEnumDeviceInterfaces(hDevInfo, NULL, (struct _GUID *) &GUID_DEVICE_BATTERY, 0, &DeviceInterfaceData);

If I change GUID from Battery to CDRom, SetupDiEnumDeviceInterfaces() will be OK.
Besides, I found that the registry on \HKLM\SYSTEM\CurrentControlSet\Control\DeviceClasses\ can’t find related guid definition of Battery.
Is that have any relationship?

Thanks in advance,
Alex

Absolutely. The BIOS in your WinPE machine is not advertising the
presence of a battery device. Just that simple. Perhaps the BIOS is
too primitive to expose the battery in its ACPI tree.

Perhaps b/c during winpe there are no battery devices installed?

IIRC winpe uses the critical device database to install drivers for devices (networking has its own path to provision the network adapter). The CDD will assign device classes to some devices to trigger necessary upper class filters. However it doesn’t install or assign a device class to every device that full Windows would.

You can try launching regedit and see if the device node for your device has any driver assigned and/or has a device class assigned.

Make sure you have the Class entry for the battery class of devices, in the
registry. The class entry for battery is

HKLM\SYSTEM\CurrentControlSet\Control\Class{72631E54-78A4-11D0-BCF7-00AA00B7B32A}

Yes, I can find this class entry for battry on the registry, but I can’t
find this key (“0000” or “0001”) under this location.
It just only have empty key as “Properties”.

The key as {72631E54-78A4-11D0-BCF7-00AA00B7B32A}context is as below:
(Default): @%SystemRoot%\system32\batt.dll,-100
Class: Battert
Class: @%SystemRoot%\system32\batt.dll,-100
IconPath: %systemroot%\sytem32\batt.dll,-2
Installer32: batt.dll,BatteryClassInstall
NoInstallClass: 1

I just find battc.sys on \system32\drivers, but i can’t find CmBatt.sys on
that location or registry on \HKLM\SYSTEM\CurrentControlSet\Service.
Is that mean my winpe environment doesn’t install driver of battery device?
If that, can I manually install it?

Thanks in advance,
Alex

Installing a driver by itself does absolutely nothing. In order for a
driver to be USED, it has to be loaded for some DEVICE. In a standard
laptop, the BIOS reports (usually using ACPI) that a battery is present,
and the PnP subsystem searches for a driver to handle it.

In your case, my guess is that your BIOS is not reporting a battery
device. No matter how much cajoling you do, Windows is not going to
load a driver for a device that does not exist.

But I can successfully get related battery infroamtion via same functions on
WindowsXP or Vista environment.
If the BIOS doesn’t create battery device, I don’t understand how do it
workable on general operator system.

Due to our environment of test station on product line is winpe, they need
to identify battery via related battery info.
Why do I can’t get battery info via SetupDixxx APIs? Is that winpe’s
limitation? or due to the battery driver was not installed on winpe?

Thanks in advance,
Alex

Winpe only installs enough drivers to boot and get to the network, that is it. I do not know how much of winpe setup we document, but there may be a way for you to write your own inf to install the battery (i would copy the full windows install’s battery inf as a starting point) and point winpe at your inf during start

I just find battc.sys on \system32\drivers, but i can’t find CmBatt.sys on that location or registry on \HKLM\SYSTEM\CurrentControlSet\Service.
Is that mean my winpe environment doesn’t install driver of battery device?
If that, can I manually install it?

IIRC winpe uses the critical device database to install drivers for devices (networking has its own path to provision the network adapter). The CDD will assign device classes to some devices to trigger necessary upper class filters. However it doesn’t install or assign a device class to every device that full Windows would.

You can try launching regedit and see if the device node for your device has any driver assigned and/or has a device class assigned.

Dear Sir,
I can use following function to get correct battery information on WindowsXP or Vista, but I can’t run it on WinPE2.0.
SetupDiEnumDeviceInterfaces() always returns FALSE. GetLastError() returns ERROR_NO_MORE_ITEMS.

HDEVINFO hDevInfo = SetupDiGetClassDevs(&GUID_DEVICE_BATTERY, 0, 0, DIGCF_PRESENT | DIGCF_DEVICEINTERFACE);
DeviceInterfaceData.cbSize = sizeof(SP_DEVICE_INTERFACE_DATA); SetupDiEnumDeviceInterfaces(hDevInfo, NULL, (struct _GUID *) &GUID_DEVICE_BATTERY, 0, &DeviceInterfaceData);

If I change GUID from Battery to CDRom, SetupDiEnumDeviceInterfaces() will be OK.
Besides, I found that the registry on \HKLM\SYSTEM\CurrentControlSet\Control\DeviceClasses\ can’t find related guid definition of Battery.
Is that have any relationship?

Thanks in advance,
Alex
