After installing or updating the BIOS with the DCSD feature: The virtual device ACPI\DELL0033\2&DABA3FF&0 may not appear in Device Manager. The device should be listed as an Unknown Device with a yellow warning icon. DCSD-related software such as SupportAssist PC Analytics may not install automatically if the virtual device is not found. The expected behavior is that the virtual device appears in Device Manager immediately after a BIOS installation or update. Once visible, Windows Update detects the device and installs the required DCSD software component. Affected Systems: Vostro 3710 Vostro 3910 For the affected Vostro platforms, testing showed that the virtual device did not appear until a second reboot occurred. This delayed detection prevented Windows Update from initiating the software installation.
No cause information is available.
Unknown Device in Device Manager If the virtual device does not appear in Device Manager after a BIOS installation or update: Restart the system again. After the reboot, check Device Manager for the Unknown Device (ACPI\DELL0033\2&DABA3FF&0) with a yellow warning icon. Once detected, Windows Update will automatically install the required DCSD software component. Note: This behavior has been confirmed on the systems listed above and may apply to other systems that support DCSD. Back to Top
