I have been trying to get my companys HP ML370 G4 server to recognise an external USB hard drive without success. As I have been troubleshooting I have noticed in device manager that there is no Universal Serial Bus Controllor. Is there a way to re-install it or activate it again? The OS is W2k3 std fully patched.

Hello, use the latest smart start for your server and install the additional drivers. http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=344318&lang=en&cc=us&prodTypeId=18964&prodSeriesId=345557&taskId=135Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Type devmgmt.msc , and then click OK . Device Manager opens. 3. In Device Manager, click your computer so that it is highlighted. 4. Click Action , and then click Scan for hardware changes . 5. Check the USB device to see whether it is working Does the Universal Serial Bus Controller show now? If not, please also check Show hidden devices under the View tab. What is the result? If it shows, please try to disable and re-enable all the USB controllers for troubleshooting, refer to: 1. Click Start , and then click Run . 2. Type devmgmt.msc , and then click OK .
