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

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

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.

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 ?

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 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?

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.

Why, since upgrading to iTunes 11, are my devices not being recognised on my MacBook Pro?

Since upgrading to iTunes 11, my devices (iPhone and iPad) are not syncing or being recognised when connected to power. Now for wifi syncing, I have to disconnect the devices from power before they are available on my MacBook Pro. Any ideas? This is really weird.

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.

USB Devices not being detected

I have a couple of problems i've been struggling with for a while, searching the forums to no avail.
1)
Firefox's UI font sucks.
Here it is compared to Thunar:
EDIT: Fixed. I had anti aliasing Disabled in .font.conf
2)
USB devices aren't autodetected after I start X.
i.e. if i plug my mouse before logging in (shell) and starting x, it works, but if i wait till later, it doesn't.
I don't think usb drives are being detected either, but I can't figure out how to try to mount them either. I would like to have automounting of usb drives and autodetection of usb peripherals.
Thanks

Device not being recognised

Help.
My i touch pod is no longer being recognised by i tunes. I have deleted i tunes and reinstalled it on my pc, to no effect. My i pod has been reset, so there is now no music on that. I was advised to close down my firewall and anti - virus as that may be the problem, and also to try a different lead to connect it to the pc - no luck with these either.
I would appreciate any suggestions.

Eventually fixed it myself. Took it to Apple Store, but they found it connected to pc there no problem. Came home used Ststem Restore on Windows as a long shot! Once again removed and reinstalled itunes, and magically it worked!!

USB storage devices not being recognised

Product:
13" Macbook Pro w/ Retina Display (Late 2013 model)
OS X Yosemite (version 10.10.2)
2.4GHz i5, 8gb 1600 MHz DDR3, 256gb HDD
Issue:
- macbook unable to recognise USB storage devices.
- can be found on disk utility but 'greyed out'.
- cannot be found under devices in finder.
- tried restarting laptop, no effect.
- additional storage via Nifty + 64gb micro SD is working fine.
- apple products (iPod/iPhone/iPad) and printer/scanner working fine, only storage devices appear to be affected.
- USB-ethernet adapter appears to be working w/o problems too.
- last technical thing done to the computer was SMC reset 5 days ago for power cable light not working properly (fixed with reset).
Hello everyone,
I seem to having some issues with my macbook and the ability to use USB storage devices. The SD card slot appears to be working fine as I have a nifty device attached on. I'm not sure exactly when this started to happen but it was working last week for sure.
I've put some succinct notes above for anyone who is willing to help out and is able to use it to determine the problem but I don't think it's a hardware issue. Maybe it's a bug with the new OS X update over the weekend?
I've attached a screenshot of the disk utility below as well.
If anyone could help me out then that would be greatly appreciated.
Thanks in advance!

Some users on another Apple thread had success in running Kext Utility last November with similar issues.
I ran kext utility 2.6.1, restarted my computer and everything was working again.

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.

USB device not being recognized due to a malfunction
has anyone got the error message ? is there a fix for this
Post relates to: Treo 800w (Sprint)

Hi phonedrn8,
The only think I can think of is if you don't have the right version of WMDC. The WMDC package has the USB driver bundled with it. If you're using Vista 64-bit and you use the 32-bit WMDC, this error would likely occur. To check your version of Vista, click the Start Menu, right click Comptuer, and select Properties. About 2/3 of the way down the new window, it'll tell you 32 or 64 bit.
Then, head over to http://www.microsoft.com/windowsmobile/en-us/help/synchronize/device-center.mspx#download and make sure you download the version that's correct for your system.
