Question about HP Compaq dc7100 PC Desktop
If we connect a USB Dongle with a Mouse and Keyboard, the mouse works but the keyboard will not, if we connect a wired USB keyboard the message comes up that it is recognized, the function buttons work i.e internet, email etc. but we cannot use the other keys. We also cannot see the device in the device manager.
Hello here is the homepage:
What keyboard are you useing ???
You maybe just need to install the driver or software for the keyboard.
Try to visit the manufactures site of the keyboard in search for software.
The driver is sometimes available at windows update.
Are there any faults in the device manager ???

I have seen this before, and the best answer I can offer you is some Motherboards are better than others when working with usb devices while no OS is in place. I actually tried using usb / to / ps/2 adapters and it still would not recognize the usb keyboard in a couple of instances. I had to get a ps2 keyboard for the installation of windows. After windows was installed I hooked up the usb keyboard and it worked fine. (just speaking from my own personal experience here)
Sorry I do not have a more technical answer for you but I'm almost 99.9 % sure this should work, providing there is no problem with the ps2 keyboard port on the Motherboard. I have never failed to install windows unless there was another hardware based issue of some kind, but never a problem with a known good ps2 keyboard.
Just double check everything is seated properly and try to get into the bios setup, if you cannot use the usb keyboard for this, you can try the usb / ps2 adapter, but if that doesn't work either then use a regular ps2 keyboard. That should work fine, then after setup is complete, windows is installed, then your usb keyboard should work fine.
