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...

What will happen if I just continue to ignore the usb/ power overload message on my tv...seeing No idea how to fix it


Samsung TV - USB Device Not Found - Power Overload error message

I'm posting this since there's very little information available that explains how to resolve the following error message that you might receive on your Samsung TV. For many months, I have been receiving an error message pop up on the bottom left corner of my screen. The error message would say "USB Device Not Found. USB1 (or USB2) Power Overload." This message popped up without me ever doing anything with either USB port. In fact, I've never even used the USB ports on my Samsung TV. The message would appear at random and stay on for a few seconds or minutes. It's more annoying than anything.

To resolve this issue, I went to Samsung's website and navigated to their support section for my particular Samsung TV model. From there, you can download the latest firmware update for your TV and copy it to a USB flash drive. Once the firmware update is on your flash drive, you'll need to extract the files since they're zipped. At that point, you'll plug the flash drive into your TV's USB port. Go to your TV's menu and navigate to the section where you can update your firmware. On my specific Samsung, I went to my TV's Menu >> Support >> Software Upgrade >> By USB. This will start the update process and your TV will reboot once complete.

So far, my TV has operated great after the firmware update. I've not received the USB Device Not Found, USB1 or USB2 Power Overload error. Hopefully this will resolve the issue for me permanently. I'll update this post if the error message reappears.

I accidentally inserted a wifi dongle instead of a flash drive into the sub port of my wireless Bluetooth boombox, the Sony ZS-RS70BTB, will this break it? The dongle was reading NOT SUPPORTED.


No, because the voltage of all USBs are 5 volts. It says unsupported because your Boombox doesn't recognise a wifi dongle. I guess it is looking for music files. The wifi dongle will be fine as it won't recognise a Boombox as it is looking for a computer or television.

Why does my PAC unit continuously flash PF at random and simultaneous intervals?


Wild guess this is a portable air machine? with a tube out a window? Wild guess, there's a condensate "leak" where it shouldn't be. The tank drain might be blocked for some reason. or level of the machine or coils are dirty in spite of the filter.

Rear USB doesn't recognize USB keys or other USB appliances


Hi,

Have you tried uninstalling and reinstalling the drivers for your usb ports?
Not all usb ports are powered, this is why there is an external power supply required sometimes. Does the usb stick work in any other port or on another computer - check your manual and see if the port you are plugging it into is powered or not if you don't have the manual it can be downloaded from the website. Having said that it is rare for a usb stick to require power..sometimes after continued use you can get a short on your port that can also cause issues and be very hard to spot, especially if its intermittent. Also check for any grunge that may have accumulated within the port.
I have also had some usb sticks that were just temperamental, try another in the same port as they are pretty cheap these days for small ones.
Hope this helps and happy to help further if required.
Here is a link to your manual.
Cheers

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 pc won't detect my printer, my printer is brother dcp 150-c


have you connected the printer's USB port to your CPU? If not, then do so. If after doing it, still your PC don't detect your printer, make sure you have a functional USB port. To check it, try using a USB Flash drive if it works with your PC. If it won't, you might have to "Enable" your USB at your BIOS.

Running XP pro on a Compaq Presario Desktop AMD. Two USB ports on front of unit worked prior to reinstalling OS . Afterwards plugging in a flash drive that worked previously... Computer will Sometimes...


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
