All 4 ports will not recognize items plugged into them. IF it is a brand new device it will for a second and try to install drivers, then there is an error message saying it could not install drivers. if trying to plug in previously used devices, the computer will not recognize them.
Did you change OS> did change the OS since bought new?
no OS stated, why does not one person here say what OS is there.???? its half the system. that.
it came new with Linux or windows XP to Windows 8.1
in 32bit and 64bit versions (click control panen, click system)
behold the true OS name and version before your eyes.
its like saying my FORD died, and no model, gee a Model "A:?
here are some facts,
most times.
dead USB is this.
you changed the OS and failed to use the HP driver at HP.com
now 1 usb chip works and the other does notl
my Elitebook does that,
I upgraded to W10 (with zero HP support on purpose)
then USB 3 ports went dead, so had to ID the chip
its a NEC chip the Intel inside is USB2 only.
then the NEC web site had my chip driver.
and now those ports work. See how not saying your OS makes help so hard, this is my example.
first test the ports only with a test mouse (test all ports now)
think small think simple and a mouse is that.
does that fail, i can think of 100s of USB devices that will fail hard in w10, all old things why not tell the helper what you plugged in.
and be web connected are you.?
tell if DM device manager shows any errors at all?
did you first use device manager, to see that device fail plugged in? and then right click it and pick update this driver.
or did DM shows all USB ports dead.? it just 2 clicks to get there.
then it fails, if yes, then MS does not have the driver,
we can go to MS right now and prove that.
if i get the HARDWARE IDs out of your Device manager page and look in the MS data base i can see if it is supported.
case in point old web cams not.
old USB wifi dongles not.
and more 100s not and 100s yes.
that is how it works and goes.
now lets got HP.com
and look first there, they made it , NOT MS.
lets say you said w8.1-64bit OS
and i show.
https://support.hp.com/us-en/drivers/selfservice/hp-probook-4730s-notebook-pc/5060893
load all the 4 lines of drivers there.
there are 3 paths here
get the drivers from HP.
get them from MS, automatically PnP or manually (ask now manually)
get them from the USB chip maker, intel or whomever.
if the USB chip really is dead, and the HP driver fails. (I bet not)
then get the hardware IDs.
tell me that and will fetch them for you easy. its really easy if you know how,and all ways how.
if this shows errors , anywhere here, the driver for these chips are wrong.! if you learn how to get the Hardware IDs its 10x more easy.

Well, appears that your configuration can handle 4 GB of memory. I checked the Acer website for upgrades for your model, and nothing appears to jump out which could solve your problem. A few appear to be possibly helpful, but some are for XP, not Vista. Upgrading "launch manager" might be a good thing.
However, Belarc tells me that on my Acer 5630 i have listed under "Bus adapters" the following:
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C8
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C9
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CA
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CB
Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC
And, under "other devices", i have a USB Root Hub (5x). Obviously, the two match. I go to device manager to check them out, finding them under 'univesal bus controllers", to see whether they are all working properly, and and they are. In addition, opening "system devices" reveals something called a "plug and play software device enumerator", and that checks out to be working fine as well. Check your equivalent out to see if you find a problem to fix. Hopefully you will. Let me know how things go.

I have the same problem with the USB's not working. Suppliers say Motherboard problem. solved it by purchasing a PCMCIA to USB port. at least i now have 2 USB ports. you could probably get one with 3 ports.

Check your Device Manager
XP
my computer right click
go to properties
then go to device manager
then go to usb
Check to see if it has an x on it if it does try new softaware
by right clicking on the USB and Update

Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.
refresh the USB ports:
1. Right click MY COMPUTER
2. Select PROPERTIES
3. Select HARDWARE
4. Select DEVICE MANAGER
5. Select UNIVERSAL SERIAL BUS CONTROLLERS
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB drive
