There is no in built driver for USB to COM in windows. You need third party driver/software to do so. If you have any device with COM port interface that device might be shipped with supporting driver, please checkout.

If you don't have, You should try this link:

Why won't the right USB port recognize when I plug in my mouse?


Your USB ports on your computer are plug and play. If you have issues with your USB port, it is port related, driver related or device related. The following solutions will help you identify the problem to resolve your USB port issues.
To Identify a Working USB Port
Begin troubleshooting your USB ports by checking Device Manager to see if your USB ports or hubs are working properly.
  1. Click the Start button. ClickControl Panel.
  2. ClickSystem and Maintenance.
  3. ClickDevice Manager.
  4. Double-clickUniversal Serial Bus controllersand check to see if all your USB ports, hubs and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
  5. If Device Manager shows any USB ports, hubs or controllers are not functioning, check for updated drivers.

To Update the USB Port Driver

An out-of-date BIOS driver can create issues with your system recognizing the USB port.
  • Watch a Video on Steps to Update Bios on Your Computer.
    1. When the update process is complete, your computer will restart again to load the operating system with the new driver version installed.

Unable to turn on from power button


This sounds like a USB problem. If there is a short or damage within the port the computor will detect it and prevent it from starting. Usually it's a USB port you always use. This may help, Plug in the mains charger and remove all USB devices. This will confirm weather its the computer or a USB cable/device. If the computer still doesn't start, get a bright light and a magnifying glass and look inside all the USB ports on the computer. In the middle of the port there is a flat plastic piece with 4 metal contacts attached to it. Check to see if they are bent, twisted or flattened in any way and with a pin or other suitable pointy device, attempt to straighten any damaged contacts. If you cannot get the contacts aligned, just try to get them away from each other and away from the wall of the port, then insert a piece of card or folded paper above and below the contact strip and tape them down. This will insulate the port and stop a reoccurance of the problem. You should find the computer starts (with a few complaints from windows) normally. this has worked for me 9 times out of 10 for this problem.
Good luck.

HP Compaq Presario V6030 usb ports don't work, is this something I can fix with drivers or can they be replaced.


First try these steps
1.Remove all the usb devices connected, then go to device manager and under Universal Serial Bus controlers uninstall all the usb root hub and then restart the computer
2. If it still doesnt work do a bios update from hp.com for your notebook and then restart and do a bios default too.
3. If these steps doesnt resolve the problem do a recovery and even after recovery the NBs usb ports doesnt work then mother board needs to be replaced as the usb ports are fixed in it.

USB not working


if the usb detects other devices and not your drive,the drive itself may be faulty.If you plug in other devices in the usb and it detects them the usb drive or its connector is most likely bad.If it won't detect any devices the port is bad and drivers won't help.Possibly a motherboard issue.

My usb port being not detected


Try downloading usb 2.0 drivers from microsoft.

Also look for drivers for your usb device..

check in device manager under usb devices and see if there is any yellow exclamation points next to any devices.

If that doesn't work your only option is to get a PCMCIA card that does USB 2.0

First of all, check in the Device Manager if you find any yellow ! marks indicating that the drivers are not properly installed or corrupted.
If you find any entries, try reinstalling those drivers by right clicking on the entries with yellow ! mark and selecting Update Drivers.
Additionally, try reinstalling the drivers for the Keyboard and Touchpad from within the Device Manager by following the steps listed below :
Please follow the steps to go to Device Manager :

Right Click on My Computer and select Properties in the list.
Now go to Hardware tab and click on the Device Manager button.
Device Manager window opens in a seperate window.
Now click on the [+] mark next to Keyboards to expand the tree.
In the list that appears, right click on Standard 101/102-Key or Microsoft Natural PS/2 Keyboard and select Uninstall.
Now, restart the computer once the uninstallation is completed so that the default keyboard drivers will be automatically reinstalled.
Now, go back to the Device Manager and click on the [+] mark next to Mice and other pointing devices and if you find any entry with Synaptics Touchpad pointing device, right click on it and select Uninstall and restart the Notebook.
Now, download the Touchpad Drivers from the Notebook for XP from the link below :
ftp://ftp.hp.com/pub/softpaq/sp34001-34500/sp34473.exe

Copy and paste the link in the address bar of a new internet explorer window and press Enter.
Save the file in My Documents or Desktop and double click the file once it is saved.
This will install the Touchpad drivers in the Notebook.
Now, try removing the USB keyboard and mouse to use the Keyboard and Touchpad of the Notebook.
If you are still unable to use the Keyboard and Touchpad of the Notebook, probably, there are internally damaged....need to get them checked by technicians.
