HP Compaq dc5750 SFF
AMD Athlon (tm) 64 X2 Dual Core Processor 3800+
2.00 GHz 1.37 GB of RAM
XP Professional SP2 with latest updates.
HP Compaq Business System BIOS (786E3 BIOS)(ver. 2.36 Rev. A)
This is a problem when a Microsoft web camera is installed prior to the boot up of the computer
The webcam works fine if it is installed after the boot up.
When any type of USB product that does not have an OS is installed in any USB port the computer freezes at the BIOS POST screen and will not finish the POST unless the USB device is removed. If there is an OS on the USB device it boots normally to that device and it also boots normally to the installed OS if the USB device is not installed.
Contacted HP Support and was told to update the BIOS, which I had already done. Then I was told that the computer was out of warranty and I could pay for the service if I wanted help. I agreed to pay if the problem was fixed. This brought a reply that they did not know if the problem could be fixed.
The next day I received an email with Critical Alerts, one showing the BIOS update I had already installed and 2 other non critical updates.
Since HP did not show any interest in fixing this problem I am posting it here to see if anyone else has had this problem.

Boot into the bios and change the boot priority order and save the setting change. Look under the Storage TAB drop down and then Boot Order. Highlight USB and press enter and then the down arrow to move it below the hard drive. Save the changes when you exit the bios.

That fixed the boot with a USB device.
But the Microsoft LifeCam HD-5000/HD-5001 causes the boot process to stop at the first blue screen showing the HP logo without the bottom line showing (F-keys). Unplugging the camera allows the boot process to complete. The camera works after installing after the bootup.
HP is aware of the problem and suggested the same solution for the problem. I have even disabled the USB boot with the same results.

Will any other USB device cause the stop at the HP splash screen?
Try the device in different use port(s) both front and back. Unplug other USB devices.
If you have a powered hub or know where you can borrow one then you might give that a try.
The Compaq DC5750 is an older PC so I wouldn't except HP to develop a bios fix for your situation.

I have tried all my USB devices and so far only the webcam stops the bootup.
This is a known problem with the Microsoft webcam and other webcams.
It has done this with other HP computers.
