USB port randomly not working

I'm having an issue where the USB port on the unit is randomly not working, it will continually flash "check" when I plug in the thumb drive and just keeping checking endlessly, i've tried unplugging and plugging the flash drive back in with no luck, i've plugged the flash drive up to my pc and everything on it is just fine. Sometimes it will actually working tho, the problem only just starting happening recently and nothing has changed in the vehicle. I was wondering if anyone else have experienced this and possibly found a way to fix it? Thanks!

Sounds like dirty contacts on the radios faceplate. If this radio is a flipdown face style then I'd suspect the contacts on the back of the faceplate that connect to the radio when you close the face. Cleaning agents vary from pencil erasers to rubbing alcohol...

I just started a new update on xbox but i get the message that it cant read the update from my storage device and that i have to reinsert it.. help me!
UPDATE VIA USB DRIVE Note The USB flash drive must use the FAT32 file system.
  1. Plug your USB flash drive into a USB port on your computer.
  2. Download the update file.
  3. Click Save to save the console update .zip file on your computer.
  4. Unzip the file. If you are using Microsoft Windows XP, Windows Vista or Windows 7, double-click the .zip file to unzip it.
  5. Copy the contents of the .zip file to the root directory of your flash drive.
  6. Unplug the USB flash drive from your computer.
  7. Plug the flash drive into a USB port on your Xbox 360 console.
  8. Restart the console.
  9. When the console restarts, the installation program starts automatically. Select Yes when you are prompted to update the new console software.

I would try this if it is having a issue connecting to the update.

If you are satisfied with this reply please thumbs up or write a testimonial good luck!

How do i plug in my dane-elec flash drive?
Remove the cap and you will expose a usb plug. Plug that into any usb port on your pc.(perfered a port on the back of your pc cause those would be the most direct and powered ports)


Hope this helps.

Computer says this drive is not accessible. It has worked fine for two years. It will work on my laptop. I am using Windows Vista
A couple of things here. First, make sure your usb ports are working on your computer. Try plugging the unit into a different usb port. For example, if you usually plug it into the back, try plugging it into the front. If this doesn't work, get a "Powered" usb hub. Your usb ports work on 5volts. Even when they start to fail, they will recognize "non powered" devices like thumb drives or camera cards. Another issue is that the power supply may be failing. Make sure you're using the power supply that came with the drive. If you say it works on your laptop, I'm thinking that your pc's usb port might be failing. A powered hub should resolve this issue. Hope this helps.

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.

Try any other computer but not open drive only see if they can read it. Also change USB port, sometimes some ports dont accept devices. Also check for latest antivirus software last such case viruses dont let me read any of my USB drives. If driver works to oter PC then you have virus.

Check to see if the back ports behave the same way with the flash drive, If so then it appears to be a software issue. If not...look closely at the pins inside the ports and make sure none are bent. If attempting to straighten pins be sure to power system off first. Also check inside the case to see that the front USB connectors are secure. Also

These units take more power than a thumb drive and sometimes the front USB ports on a computer just don't push enough current to recognize these players (I have the same issue).

Try plugging it into the back USB ports.

Also, make sure your USB ports are working correctly in your device manager.
