Try other ports in your laptop aside from the one you tried to plug into. Some USB plugs do not plug well into the USB port. It may be a factory defect. If it is still under warranty, you may have it replaced. Make sure you bring your laptop with you when you do this to make sure the new USB hub works.

Machine will only respond with desk top not lap top computer when doing embroidery. why?


Could be a number of reasons, as I don't know what response you are/are not getting or what messages you're getting. First, do you have the same operating systems on both machines? (Windows XP, Vista, 7) There's a patch available for Windows 7 on the Futura website at www.Futura-support.com that should allow the Futura software to run on this operating system.

Another reason could be with the USB ports. Not all USB ports provide the same amount of power, and the Singer machine and USB cable require 12V. On a desktop, you normally have to have the cable plugged into the BACK of the computer, not into a front port or USB hub. If you're getting a message on your laptop that the cable isn't plugged in, then this is most likely your problem. If you're using a USB hub, plug the cable directly into a port on the back of your laptop. And if that port doesn't work, move to another port, trying each one on your laptop, until you find one that works. That port has the power that you need.

I hope one of these solutions works for you.

USB devices not recognised or not working properly?


Try these steps to reinitialize your usb ports on your pc

1. Unplug ALL USB devices connected to the computer. If you are using a USB mouse and keyboard, temporarily use the older type PS/2 devices if you have them, if you don't then just leave them connected.

2. Hold down the windows key and press r

3. Type devmgmt.msc into the run menu and press ok

4. Click on the + sign next to the Universal Serial Bus Controllers

5. You might need another mouse to do this if you have a usb mouse.. I recommend you get a ps2 connector mouse which goes into the green round connector in the back of your pc.

6. Right click and uninstall first the usb root hubs. all of them then uninstall the rest of the devices you see under Universal serial bus controllers

7. Ones you have uninstalled everything you should see the Universal serial bus controllers there at all.

8. Now go ahead and restart your pc.

9. Ones you have restarted the pc your usb ports will reinstall in a moment stand by while it installs all of them. If you get warning messages click ok or continue installation.

10. Now go ahead and plug the usb devices back in. Install software if required, all usb devices if not faulty or broken should work now. Also note the error code if you get one?

This solution doesn't fix all usb problems so if you have a yellow ! mark there and device status reports a error code. Then it might not be a problem with your usb ports.

Thank you for reading, do leave suggestions, comments, feedback below.

In the right pane, look for an entry named Start. If you find one delete it. Your USB devices should start working immediately.
If not please report back.

One day the Belkin 7 port hub works the next day it doesn't


Your problems with the Belkin 7 port are not due to the Dell computer or the XP OS. To problem solve, select on USB port and stay with it, not the 2 top ports for your keyboard and mouse. 1. Plug in the power adapter, wiggle it about, widen the prongs, change outlets at the 120 v. end. 2. Use an simple hand magnifier and peer closely at the DC input plug and be positive that the center post and the minue side piece of metal if in firm constact with the plug. If cannot insure a firm fit, sligtly bend that tiny metal piece towards center. Option 2, use another adaptor with the precise voltage as the original and the idential pin that inserts into the module. 3. Use another or new USB connector.
This list does not imply a specific order of diagnosis. Your fundamental problem is the failure to delive DC power to the Belkin hub or to capture the hub to USB port signal. In a phrase, you gotta short somewhere.not an issue with the computer or the XP operating system. Bill Miller

My Kingston USB 2GB can't work in my desktop pc .


There are two most common causes of Pen Drive not working
1) The usb port You are connecting it has not enough power output to operate the pendrive (many older computers and laptops have this issue) solution buy an powered USB HUB one with a power adapter You put in a wall socket and then connect Your Pen Drive thruu this hub
2) Operating system lacks drivers for Your particular Pen (windows up to Millenium lack proper usb support and newer I mean XP Vista? (Not sure bout this last one) need administrative privileges to recognise some Pen Drive for the first time or even a driver diskette (some very rare cases).
