I can't find my usb device on the mac

Go to Disk Utility, in your Utilities folder in Applications, and see if it is listed there. If it is try mounting it in Disk Utility.

What if it's still not listed on the left under Disk Utilities?

My problem seems more extreme: my MacBook Pro (2015 13" Retina) cannot detect USB drives, either in Finder, Disk Utility or Terminal. The drives work fine in an almost identical Macbook. Both USB ports give the same outcome, so a hardware defect at the port seems unlikely. Any ideas very welcome!

THANK YOU SO MUCH!!!! I just bought my Mac and im new to it, and you helped a lot!

Now this is what i figured out. If I cant see my USB device, i go to >Utilities>Disk Utilities> [the window pops up] and i find my USB device on the left hand side. Now this is what i did; i had Finder opened and so i dragged the USB device from Disk Utilites into the left hand side of the Finder window, and then it was visible.

Thanx A LOT!!! i now can do this to the macs at my Uni. 🙂😎😀🙂

Okay I was having the same problem too, where I opened the Disk Utilities and nothing was there. What I simply did was downloaded an Android file transfer for Mac. The Android file transfer will show on the left hand side of the Finder window and it will also come up when the device is connected to the Mac. You can go here to download. http://www.android.com/filetransfer/

I have a dbtech slider scanner connected via USB that I am trying to use and my Macbookair does not see it in devices. Devices does list however a remote disc that I do not have connected. Is this a similar problem to others listed or how do I resolve?

thanks

I have a similar problem with my Macbook Pro. i bought it only last September and had never used a Mac properly before. I've tried an Iphone 3G, Android Phone and now a Nokia Lumia 625 (windows mobile OS). I can connect the Iphone, edit content via Itunes and it opens Iphoto. The Lumia also opens Iphoto but I can't see any photos that are on it. Both charge and show some sign of acknowledging the connection.

I have used a USB Stick (I'm not technical sorry) with the laptop before and set up a printer but I have never been able to find any external media devices (Iphone, Android phone, Windows phone, Ipod nano) through finder or on my desktop when they have been connected.

Then I try to find to find them both in finder. In finder's preferences, all 4 boxes under devices are ticked (My Macbook Pro, Hard Disks, External disks and Cds, DVDs and Ipods)

When I open the disk Utility app, there are 3 items on the left hand menu: 500.11 GB APPLE HDD ST500LM012 Media (my harddrive I assume) with a subcategory Macintosh HD. Then under those is a greyed out SuperDrive.

The Iphone has definitely worked with a Windows laptop before and as I said, I just can't find the devices in Finder. Sorry if my description is a bit erratic, i was trying all the fixes people have suggested here as I wrote it to make sure I didn't fix it. Any help would be appreciated otherwise it may be a trip to the apple store on saturday. Thanks for reading 🙂

I tried all of the previous recommendations in this thread and I still can't "find" the USB that I plugged in. I've used this USB many times before and this is the first time that it doesn't show up when I open my Finder window. Did you get any other information on what to do to find your USB?

In addition, I sometimes have the same problem when I plug certain USBs into my printer. This is a recent problem that just started happening--it's never happened to me before and I've been using Mac for about 2 years now.

It seems that your question has not been replied yet. I also have the same problem as you and I desperately need the answer to that. Have you gotten the answer yet since your question was posted last year? (in another thread or etc.) If yes please let me know. Thanks.

I am having this problem too. Opened the Disk Utilities but everything is grayed out and I can't click on anything. I JUST bought the iMAC and didn't get the disk port when I bought it. Do you have to have that to have access to the usb ports? It was charging my device, but I couldn't use it in any way.

iMac family must have! Huback make you more convenient to use USB.

To put it bluntly, Huback is a USB 3.0 Hub only, but it is not just a USB Hub only through the precise size and design ingenuity, Hubackconnect the computer end of the USB cable to make a similar fixture design, so that can be firmly clamped Huback the iMac, the USB extend below the front screen, not only easy to use, but also eliminates problems on the table the whole line, more beautiful.

You might also open FINDER PREFERENCES>GENERAL and see what boxes have been checked.

Ciao.

For my sansa clip, I just had to change settings > Systems Settings > USB Mode: from MTP to MSC.
