Kodak scanner i3400 error e73


e73 is A USB command failure. Check to see if the scanner is connected to a USB 3 port. A USB 3 port can be identified by the port being Blue in color or have the letters "SS" (Super Speed) near the port. Kodak scanners behave strangely with USB 3. With the unit turned off, please connect the scanner to a USB 2.0 port. Additionally, download and install (as an administrator) the most current drivers from Kodak.com which alleviates 9 out of 10 issues.

My netgear wireless-n150 USB adapter wna1100 can't detect adapter.


First determine that the USB port isn't dead. Do other things work in that USB port? If the answer is yes we know it's not the port. Have you tried another USP port? If it doesn't work in another port (or on another computer's USB port) then it's the adapter itself.

Adapters can go bad. USB ports usually work and don't go out. The exception is that many laptops that come with several USB ports sometimes have one (or more) that never did work.

Try it on another computer. This is one last step to determine if the adapter itself is dead and that it isn't something on/with your computer.

It also could be that the computer has the old USB 1 port and the adapter needs USB 2. (USB 1 was slower).

Problem with usb port don`t work


Step 1
Before you start working on the USB port, make sure that your device is not the problem. If the computer says that the there is a new USB device but that it cannot use it, typically there is a problem with the device's driver and not the USB port. If this is the case, your best option is to re-install or upgrade the device driver. Try inserting the device to another computer. If the device works, most likely the problem is with the computer and not your device.

Step 2
Try rebooting the machine. Rebooting a computer resets all of the software to the default state and will clean up many issues. The start up process also checks all of the devices on the computer and can sometimes fix a USB port. First shut down the machine. Connect the USB device up to the computer and start it. This reboot will sometimes fix a bad USB port.

Step 3
Try attaching the USB device on to another USB port on the same computer. If the device now works, the old USB port probably has a hardware or BIOS issue. Skip to step 5 to try to fix a bad USB port through the BIOS. Fixing a hardware problem on a USB port requires working on the motherboard which is typically more expensive just adding a new USB ports.

Step 4
Uninstall your computer's USB device bus manager. The device manager controls the USB access and sometimes gets corrupted. Fixing the USB device manager requires administrator rights on the machine. The best way to uninstall the device bus manager is to right click on your computer's icon and select properties. This will bring up the hardware settings for your machine. Click on the hardware tab and select the device manager. The device manager lists all of the devices on the computer. The next step is to open up the "Universal bus controller" option. Right click on all of the items under this option and uninstall them. Once all of the devices have been removed, restart the machine with the USB device connected. Upon reboot, windows re-installs the USB device manager. Most of the time, this will fix the USB port.

Step 5
The next thing to try is to check the BIOS. Restart the machine and enter the BIOS setup screen. You should check to make sure all of the USB ports are active. If they are, you should try resetting the BIOS settings to the defaults. The BIOS reset will sometimes fix USB port. But if it does not you will have to consider upgrading the BIOS. Upgrading a computer BIOS is very dependent on the motherboard manufacturer and you will have to visit your computer manufacturer's web site for detailed instructions.

Step 6
The last trick to try to fix a USB port is to repair your OS. Sometimes the USB drivers can get corrupted and break the USB ports. You can reinstall the system files onto the computer which should fix the USB port. Your data files should not be changed in this process, but it is a good idea to do a full backup of the computer ahead of time. In windows, an OS re-install is done by loading up the windows installation CD/DVD and selecting the repair windows installation. Just follow the steps and you often have a fixed USB port at the end of the process.

Mouse can not work


this is usually do to a port going out or the total failure of the mouse.. or if it's a rather old mouse, the ball underneath is too worn to work.

if it's the port, there are 2 kinds, one is a round port (PS/2), you will have to turn off the computer to remove the mouse from this type of port.

if it id the round ps/2 port, you will have to either get a new mouse using usb, or you can try a new ps/2 based mouse. 

REMEMBER you cannot plug in or remove a ps/2 mouse while the computer is still on!

The next port, and most common is the usb port. it's a small rectangle.

You most likely have atleast 4 of these on the back of your computer, and most of the newer computers have 2 on the front, sometimes in a hidden panel.

Sometimes if you are a windows user, windows will set a usb port aside for what normally resides there, and a mouse in a port that usally houses a printer usb plug will make windows not see the mouse sometimes.

Removing a usb port mouse is rather easy, you dont need to turn the computer off to do so.

Before considering replacing a usb mouse, try putting it into another usb port. sometimes this will work. also, see if the lights are working underneath when plugged in. (optic mouse, not ball mouse). 

if you have determined that your mouse is broken, then the next step is to replace it. bestbuy sells mice for about 25-30 dollars.

if you dont mind waiting 3-7 business days, a reputable online retailer like 3btech.net can sell you a mouse for about 15-20 dollars, and 3btech does not charge for shipping.

Targus Travel USB 2.0 4-port Hub


sometimes usb hard drives will not work through a usb hub.
if the drive works connected to the laptop but not the hub then that's how you'll have to use it.
it's also possible the laptop cannot power both the hub AND the drive, in whaich case you'll need a powered hub (one you plug in to the mains).

The usb of my dell latitude c400 notebook is malfunctioning


Unfortunately, I have seen this many times. One of the major problems with the C400 model was the USB port failing. I have had many of them replaced under warranty, and I have repaired some. The USB port breaks loose from the mother board and stops working. It is possible to SOMETIMES disassemble the laptop enough to get to the port and re-solder the USB port connections. But is is a slow process for experienced people. And it does not work all of the time. i know that this is not the answer that you wanted.

Good luck with it.

USB powerloss?


As you have already stated that the port in question can run a standard optical mouse, the port seems to be working fine.

Sometimes the drivers for a USB device need to be installed for each USB port. Maybe you have installed these drivers for 3 of your 4 USB ports, but not for the one in question, result of which is the problem you face.
