ALL uSB Ports stopped working

NO PC stated ! (impossible to help much)?
No simplesave model stated, some are huge hdd others not. some are ssd.? matters big time what is there.

power is FIRST>! no power no joy

does the actual drive removed work inside any PC? yes/no? (it is SATA drive actually there, simple)
if no,it's bad. if yes?, the external needs help. (ask)


SIMPLESAVE is just external HDD./ this

did you forget to USE THE HP power pack to it?

no huge 1TB hdd, will run lacking that, impossible
but easy for SSD and 1/2 the time with 2.5" drives.
it weights 2.2lbs so is 3.5" large HDD like I have
I've built 3 from scratch, (USB3 -Esata too)

lots of models of simplesave, or 10 years.
some have power pack, (2 lb drive) above, .
others none, and thin and light.

the problems are manifold
1: using USB1.1 port, ? try them all ?
2: using USB2 but DM shows it is only 100mA port or 500ma? (works on 2.5" but not 3.5" drives)
3; power pack not plugged, in
4: ;unstated OS infected or USB ports dead, (drivers bad)

making the 3.5" drives HDD, work can be hard.
cures here.

if yours is the tiny one, 2.5" test it on all USB ports , if fail try other PC, with 500mA ports
work now good, no the HDD is bad,
test HDD removed now.
ive been running huge HDD external since the first ones ever, and never have problems, (I build my own)

first test is :
make sure USB finds it. in Device manager.
then see if diskmanagment, shows it.
if it does and no drive letter , then give it one.

ALL USB ports? In Windows Vista , run Windows updates to verify you are current. Run HP updates software. Take a look at this and run the Microsoft Fix-It: http://windows.microsoft.com/en-us/windows-vista/tips-for-solving-problems-with-usb-devices

Not responding to what device? Your computer is getting a litte long in the tooth, if the USB device is a Thumb Drive over 2GB's it may need a Patch/ hotfix. Open HP updates and Windows updates. Or is there another issue.

Then the motherboard is defective

Most likely the USB driver is corrupted.  Uninstall the one you have now from Device manager, reboot and when the New Hardware wizard appears let it get it from Windows Update.

Check to see if something else will work on the side port. It may not necessarily be a dead port. Just something you should know too; I used to work for Wal-Mart in the electronics department and they had to recall all their firefly flash drives because they had a tendancy to malfunction. Try using it on a different computer, it might just be a dead flash drive. I hope this helps your problem and I hope your flash drive didn't have anything too important on it :x

make sure all five wires per port are hooked up as the manufacturer says to hook up

Get a new USB driver from HP website. Yours may have been corrupted.

Most likely a motherboard problem, though you can try and re-do windows, best bet on getting it all to work is Turn off CPU, Unplug Power cable, And all usb devices, let it sit for about 20mins. Plug it all back in. Turn on the CPU! Though this might really get on your nerves having to do this multiple times, id get a new motherboard.

not likely,
what pc model???
try serach for usb software. your might be too old. "usb2.0"
