Question about Compaq Computers & Internet
P?using win 7 64 bit t3500 cpu usb ports wont run anything, tried different flash drives and different usb mice hel
This should be pretty easy to fix. I have seen this many times before. Here's what to do:
Go into device manager and expand 'universal serial bus controllers'.
Start at the very bottom, and start deleting the usb root hubs one by one. You will lose your touchpad control at some point, as the touchpad is actually a usb device. One of thwo things will happen.
1. The usb hubs will automatically be re-detected and re-installed.
2. You will just lose touchpad control after deleting one of the root hubs. If this happens, then shut down using the power button, and restart. Th usb hubs will be reinstalled once you log back into windows. Please let me know if this doesn't fix it.

Two solutions would be to either restore your pc to before the problem started,using system restore on accesories menu, or use the recovery cd or the recovery folder Acer laptops usually have on the 'D' drive and re-install usb controllers and drivers.

SOURCE: HP Pavilion zv6000:
After reading the description, I think you need to try updating BIOS and latest device drivers for USB. Because USB are getting power on that means there would not be any fault to from the motherboard.
So please try updating latest BIOS for your notebook.
If you can provide me the product no for your notebook and the operating system which you are using currently then I can find the one for you.
Otherwise you can also do the same.
Type in the product no. on www.hp.com. Then go to software and driver download page, select the proper OS and search in BIOS ROM pack available for your notebook.
I hope this will help.

Tips for a great answer:
click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X
you will need to update/reinstall drivers
right click to reinstall drivers
if you can see your usb drive but its not working
ports (com&lpt) right click update driver if this fails to fix the problem
check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts
is the mouse a usb or ps2 mouse
if its a usb mouse and not working you might have to use a ps2 mouse
or try it in safe mode
restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse
allowing you to attempt to repair your computer
hope it helps
