The left USB port does not work at all. I have tried several devices and USB chords with no recognition by the computer and no power to the devices. I also tried uninstalling and restarting the computer already per instructions from other posts. There also does not seem to be any physical damage. Is there some other step I should try or is there a way to install a new port(if thats the issue)?
Side note: I do not actually know if it's 32 or 64 bit Windows 10.

Welcome to the HP Support Community!
In your post, you had said that currently your HP Pavilion dm4 Notebook does not recognizing a USB device. Here is a link to troubleshoot USB connections.
I would uninstall everything listed in the Universal serial bus controllers list with no USB connected at the time of uninstall.
Please note remove any and all USB devices, and remove memory cards from the card reader slot. Disconnect all non-essential devices before uninstalling Universal serial bus controllers.
Restart your computer and then insert the USB device.
If the above does not help you could try using the Windows Update Troubleshooting tool to fix any updates that have not come through for Windows. This is a download. http://ow.ly/X9lAd.
Please let me know how this goes.
