USB port not being recognised

Hello,
When I plug in my mouse, the light leds of the mouse light up, however my mac does not recognise it (it doesnt work)
The same goes with a USB flashstick, once i plug it in either of the 2 ports, the USB flashes, however my mac does not regonise it.
It's been going on for a long time, resetting does not work as well as the PRAM reset
Does anyone have any solutions?

HT4619 MEMORY STICKS IN USB PORTS NOT BEING RECOGNISED

I am setting up a new iMac and uploading images and videos from other computers. My iMac will not recognise memory sticks inserted into the USB ports. Can anyone assist please?

Thank you for replying. Both new sticks were used first in windows based computers at work and I tried to download images on my home iMac. I have been able to connect iPad and iPhone through the USB ports.
I have also found that some music CD's have not been recognised in the DVD/CD slot.
I have a lot of learning to do.

My Canon PIXMA MG2440 USB is not being recognised and I can not print anything..?

I cannot use my printer as the USB is saying its not recognised.
I never needed a driver for this printer before and it used to work fine.
I have no idea how to get my printer to work as I cant connect it to my laptop?

Hi mrsrsimmo,
If the printer is not being recognized, please try connecting the printer to another USB port on your computer, and also use a different USB cable if you have one. We also recommend installing the latest drivers and software for the printer. Since you have the PIXMA MG2440, please click here to go to the Support and Downloads page on the Canon Europe website where you can download the drivers.
Hope this helps!

USB Modem not being recognised in OSX

Sorry if this is being posted in the wrong forum.
I have an oldish Usb modem (Intel(R) AnyPoint(R) DSL Modem 3240 http://www.intel.com/support/network/dslmodems/sb/CS-009978.htm) that I have been using for a while with my PC laptop.
I have recently updated to a MacBook and was expecting this modem to be fine since it has worked succesfully with a friends older iBook (he simply plugged in the usb cable and was able to connect to the internet once I gave him the Username/Password. No software installation was required) but on my MacBook the modem doesnt seem to be recognised.
I have followed the install instructions to the letter but when it comes to plugging in the usb modem nothing happens and no modem is found (the l.e.d on the front of the modem stays off)
If anyone has any suggestions that would be great. I only need access to broadband very occassionaly and would like to avoid having to buy a new modem. Thanks
MacBook Mac OS X (10.4.6)

Generally usb modems don't work or don't work well on Macs
IMO, that is a bit of a sweeping statement. Most people in the UK use a USB modem, not least because they were supplied free by your ISP.
Get a modem with ethernet
Better still get a router, which what many UK ISPs now provide free.

Qosmio F10 - USB devices not being recognised properly

Hi there,
I've been having major problems with the USB ports of my Qosmio F10. When ever I try to plug in a USB device, the F10 recognises there is something there, but always categorises it as an unknown device. For example, everytime I try to attach a USB mouse, it does not instantly recognise it, even after previously having gone into the device manager and manually installing a driver.
This has been the case since I bought the laptop 5 months ago, but I cant ignore it any longer.
I have already tried :
- uninstalling all USB controller and hub drivers and reinstalling
- making sure that power save for the usb devices was not ticked
-ticking "install software anyway" in the driver signing options
When I open up device manager my USB looks like this
- Intel (R) 82801DB/DBM USB 2.0 Enhanced Controller - 24CD
- Intel (R) 82801DB/DBM USB Universal Serial Host Controller - 24C2
- Intel (R) 82801DB/DBM USB Universal Serial Host Controller - 24C4
- Intel (R) 82801DB/DBM USB Universal Serial Host Controller - 24C7
-USB Root Hub
-USB Root Hub
-USB Root Hub
-USB Root Hub
Any help on this is much appreciated as its driving me nuts :-)

Hi
I agree with Jack. You have suggested that the USB devices were recognized but as an unknown device. In this case the device drivers are needed.
Which USB devices did you connect?
Sometimes some USB devices cannot be recognised properly because of the low power of the USB ports. If the USB device needs more power than 500mA standard power the OS could has some problems with the recognition.
In this case you need a external power supply or a USB hub with the power supply.

USB port not being shown

I picked up a Toshiba Satellite 325 CDS at a garage sale and plan to use it for Ham radio and electronic hobbyist pursuits. I'm running Windows 98SE. Everything works well except the USB 2.0 port, which is not being recognized in the Windows Explorer listing of available drives. A memory stick inserted in the drive does not show up. I have deleted the USB and let it be reinstalled, to no avail. What proceedures can I follow to identify the problem?

Internet usb dongle not being recognised.

When I connect the usb internet dongle to my MAC it does not recognise it.

Did you install the dongle drivers for your operating system. Look on the dongle provider's site for drivers and install them in accordance with the provider's instructions.

Is anyone using VMware fusion and having trouble with USB devices not being recognised

I have an Terratec Axon AX50 Guitar to Midi interface. The editor software is not Lion compatible so I have attempted to run that bit in Windows 7 on a virtual machine.
The problem is that the VM machine will not recognise the USB device, even though when it asks which machine I want to connect to it names the device correctly.
Any Ideas ?

Usb devices not being recognised

hello my external devices such as my printer or edirol sound recoreder are not appearing on my desktop when i plug them in. After seeking advice i have located them in the system profiler (usb part) and it can read and recognises them. however i do not know what to do next does anyone know what to do as i have no idea and really need it to work for my uni work, please help cheers

First welcome to the discussions.
Most USB periperals come with either Cd or software to run them. Printers, Scanners, Cameras, and some don't.
Each one can be a little differnt. I will use a Printer, If it is compatible.(OSX has some drivers installed to use these devices but not for all.)
First let's start from scratch pull the power on your printer, and wait a minute or so. Plug it back in and restart your computer.Make sure the USB is plugged in when you do this, This will reset the printer and the computer.
place the disc that came with the printer in and Install the software, as soon as you are done go to your printer manufactures site and search for the latest download for your Printer and Operating system. Download it.
Go to your Mac HD and then Applications folder and you will see a folder that matches your printer,drag the folder you downloaded from there site to this folder and double click it inside that folder. Depending this printer folder can be named different things, such as (HP952c Printer) or set up or Install. It can also be located in the Utility folder.
Open it and see if there is an Install option. click it and launch it.
This may seem a little confusing, but it's not really,
Most people have problems with one of a couple a different things.
Either there printer isn't compatibble,
Or they havent opend the folder in the Applications, or Utility folder to launch there printer drivers.
After you read this it should be pretty easy for you. Come back and tell us if this helped. Don

Mobile phone not being recognised via USB port

A few days ago I plugged my Motorola V3x phone into a USB port to download some pictures and was presented with some Windows to fill out some information. As I could not complete the operation at that time I closed the windows to retry at a later date. But now when I plug the phone into the USB port it is not recognised and there is on icon appearing on the desktop indicating that a USB has been plugged in. If I plug other devices into the USB ports they are recognised. Any ideas?

For the phone to appear on the desktop when plugged in via USB you need to use USB Mass Storage mode (or whatever Nokia call it) not Media Transfer.
For iSync you need to download the E71 iSync Plugin from the Nokia web-site:

USB Audio CODEC not being recognised.

Hello,
I have my my Wharfedale 802 mixer plugged into my MAC Mini (late 2012), Processor - 2.5 GHz Intel Core i5, Memory - 4 GB 1600 MHz DDR3, via USB however it is not being recognised as USB audio CODEC what so ever. I have also tried searching for this to set the outputs in Logic and it is not recognised there either.
I have just updated my iOS to Yosemite 10.10.2 and also my Logic X does anybody know why my mac is not recognising my USB audio CODEC for an input or output?
Please help.
Thanks

I just posted this problem I had also. The USB audio Codec is for PPC macs only. I couldnt get a PYLE USB cassette deck to work in AUDACITY because it needed that codec.Windows users use this codec for many devices including the one you are trying to connect.
My post in Snow leopard forum:
I have come to the conclusion that this codec only worked on Macs that used PPC chips,not Intel Macs.Apple must have dropped it when switching to Intel.No where on the net can I find anything about this codec on newer mac OS's and newer Macs.
Judging from this user's comment and others,they are working with OSX10.4 or newer OS that has PPC support like the first Mac Pro and other PPC's.I think the comments below answer my own original question.Hope this helps anyone with the same kind of problem with USB devices that need USB audio CODEC.
In Audacity prefs, I selected:
"USB Audio CODEC" for both Input and playback.
I even tried lower sample rates and such. Record button stays grey and readouts don't show any input whatsoever even though I am sending a signal.
Mac is a 533Ghz g4 (Digitial audio) running 10.4.11
It is plug into a USB port on back of machine.

My iphone 3GS is not being recognised by my PC?

My iphone 3GS is not being recognised by my PC, either in itunes or My Computer as a drive. iPad and iPod work fine.
Phone also not found on other computers I have tried.
Tried resetting the phone. Reloaded iTunes. Stumped now.

Now sorted thanks. It was the cable, seemed identical, would charge the phone through the USB port but did not show up as a drive.

Ipod not being recognised, but with a twist

Hi,
My ipod nano 5th Gen is not being recognised on my computer. It is now being recognised by the computer itself sometimes, but not itunes. However, when I plug my ipod into my partners laptop, its fine. More to the point, when they plug their's into my laptop, it recognises them. To me, this suggests that both my laptop and my ipod, individually at least, are working.
I have been through the ipod support page, and gone through all the steps, and to no avail.
Final details. I'm Windows 8, and my itunes is totally up to date. I have re-installed iTunes, and have reset my ipod to factory settings on another computer. It still doesn't work, please help if you know anything about this!!
Cheers,
Ralf

I have the same issues. itunes 5.0.1.4 doesn't recognize my mini. ipod updater doesn't recognize my mini either. i have uninstalled itunes 5 and reinstalled 4.9, but it didn't work still. something in itunes 5 changed something in my system that reinstalling 4.9 doesn't fix it. updater just shows that i have no ipod connected. if i try to get updater to check for my ipod during the updater installatin, it just sits there and says "waiting for ipod". it's not my usb port because i can read and write to my ipod. i did the entire list of chores that apple suggests on the site including disabling all other functions and services, reinstalling the com port, uninstalling everything, reinstalling everything, getting windows install clean up, e v e r y t h i n g! nothing worked.
I then installed itunes 4.9 and updater 1.4 in my other laptop. i was able to update to firmware 1.4 using that computer. when i put the ipod into that computer w/ itunes 4.9, everything works fine. of course, it asks me if i want to link that laptop w/ my ipod. i said no, because i want to use my original laptop w/ the ipod.
anybody have a solution for this? it's like we all have the same symptoms and going to the same doctor and we end up having to diagnose ourselves. this is extremely annyoying and inefficient.

My ipod touch 4g is not being recognised on my new toshiba laptop. The ipod touch starts charging then stops. This keeps continuing. Please help.

my ipod touch 4g is not being recognised on my new toshiba laptop or itunes. Its not being shown on my computer and its not shown as 'unspecified' in the 'devices window'. The ipod touch starts charging then stops this keeps continuing like a ongoing circle. Please help.
I have tried on my family members laptop and its seems to be picking up. So the ipod or the usb wire is not the issue.
I have tried everything from reinstalling itunes and updating windows.
I have tried the diagnostics test and its still says the ipod cannot be found.

See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:
iOS: Device not recognized in iTunes for Windows
paying special attention to item #5
- New cable and different USB port
- Run this and see if the results help with determine the cause
