USB flash drive not recognised

I have just bought a CamSports EVO helmet camera and my Mac won't recognise it. When I plug it in to the USB port it charges but will not show as a drive on the desktop. I've tried it on other Macs and it won't work on those either, but it appears straight away on Windows computers.
Camsports website says that the camera is Mac compatible (v10.4) but I'm wondering if there is a driver missing from 10.6.
Can anyone help please?

Hello,
You should download the new firmawre here: http://www.camsports.com/images/stories/camsports/firmware/EVO%20Color%20Firmwar e.rar
Expand the .rar archive and copy the folder in a Window Computer
Open the firmware folder and launch FULL_isp.bat
The program is waiting you to plug your camera
Then plug your camsports evo color and immediatly hold the on/off button of th camera (it's the main silver button on the body)
The program starts to load the files of the new firmware
Press enter when appears the message: "Thank you for using magic pixel usb tester"
You can unplug your camera and try it on your mac.
I just did it and it works.

USB flash drive not recognized by Macbook Leopard 15.1

Hi
Until last week my macbook was able to recognize my USB flash drives and my IPOD in Itunes and also as an independant drive.
Last week it started to give trouble. It simply does not recognizes any USB flash drives I plug in as well as my IPOD music into Itunes.
This is very strange since it is recognizing the HP all in one. It scans and prints. I purchased this HP all in one last week and installed the software for it. I am not sure how this could have affected that I cannot mount any USB drives.
Can you please help? Anyone?
Thanks.

Hi
Welcome to Apple discussions
Can you see the devices if you use Utilities/Disk Utility? Maybe you need to reformat them. Take care, reformatting will lose the data on the device.

USB Flash Drive not mounting

I recently bought an 8GB USB flash drive, which came formatted FAT-32. The drive was put into a friend's Windoze laptop and had a couple GBs of jpeg and avi files transferred to it. I took the drive home and put it in my white MacBook (4GB RAM, Leopard 10.5.8) and it would not mount. I put it in my G4 MacMini; likewise, it wouldn't mount. I am assuming it also won't mount in all my older Macs with USB, either. I returned it to the Windoze laptop, and it ALSO wouldn't mount this time, except as one pulled the flash drive from the Windoze laptop, for a second a window with the flash drive's contents would flash on the desktop of the laptop. Originally, the flash drive was "properly" ejected from the Windoze laptop.
On the MacBook, both Disk Utility and DiskWarrior do not see the flash drive when it is in the USB port (either port). However, Apple System Profiler does recognize when it is plugged into the port. ASP returns the following information when the flash drive is in the high speed USB port:
"Flash Disk:
Product ID: 0x3234
Vendor ID: 0x1221
Version: 0.00
Serial Number: 10000000000003CF
Speed: Up to 480 Mb/sec
Manufacturer: USB2.0
Location ID: 0x24100000
Current Available (mA): 500
Current Required (mA): 100"
Anybody have any idea what is the cause of my problems with the flash Drive and how I can get the drive to mount? I don't think the problem is a function of my Apple hardware, as my USB ports on all my machines function with everything else USB which I have without problems. Thanks.

I know that, but I have USB in my older Macs, too, and besides, some of the most knowledgeable people are in these older forums!!
I've come to the conclusion that the drive may be defective, too, but I was just looking for some possible angle which I'd not already considered. I tried reformatting, but without the drive even being recognized, it isn't even possible to reformat. I can only get ASP to indicate that it is attached.
Thanks for your try!

USB Flash drive not showing on DT

Hi folks,
I received a USB flash drive with 2 GB capacity made by Super Talent (www.supertalent.com- look under Aluminum flash drives).
Upon plugging it into the G5's USB port (i've tried them all) I get a "Cannot recognize- Initialize/Ignore/Eject" message. Clicking Initialize brings up Disk Utility which sees the drive with a capacity of..wait for it..2 Terabytes! Here's DU's info:
Name : SKYMEDI USB Drive Media
Type : Disk
Disk Identifier : disk1
Media Name : SKYMEDI USB Drive Media
Media Type : Generic
Connection Bus : USB
Connection Type : External
USB Serial Number : 03

Total Capacity : 2.0 TB (2,199,023,255,552 Bytes)
S.M.A.R.T. Status : Not Supported

Selecting HFS+ (journaled or not) or MS-DOS then clicking Erase gives me a spinning beach ball requiring me to Force Quit DU.
My config: G5 DP 2.0, 1 GB ram, 10.4.6
Any thoughts?
G5B DP2.0 & iBook366SE Mac OS X (10.4.6) Alu 20-in Display

hey there scan,
I gave the drive to a friend who has an iMac. Samething occurs: drive does not mount, DU erroneously reports 2 TB capacity and coughs up the beachball seconds after clicking on Erase to format it. He's on 10.3.9 while I'm on 10.4.6.
All the ports on my G5 are in working order as i use printer/scanner and iPod w/o problem.
Think the drive is going back.

Usb flash drive not mounting when inserted (SOLVED)

Well, there are the on-line manual pages:
man ivman
man IvmConfigActions.xml
man IvmConfigBase.xml
man IvmConfigConditions.xml
man IvmConfigProperties.xml
And there are examples in the default files (/etc/ivman/) provided with Ivman.
But that you probably already know. I'm not familiar with any other docs, except maybe tutorials on the net if you count them as docs

USB Flash Drive not detected after OS X Mountain Lion installed.

My MacBook Air 11 inch (Mid 2011) suddenly stopped detecting all my USB flash drives a week after upgraded to Mountain Lion.
I have a tiny 16GB USB flash drive (Sandisk Cruzer Fit), for daily work, that has never been unplugged from my MBA.
Everything was fine on Lion, and a week of Mountain Lion, until just when my MBA prompted me that my flash drive "was not ejected properly" after I re-opened the display/lid, or from sleep mode.
I thought I might have accidentally removed the flash drive unknowingly. So I tried re-plugging the flash drive, closed and re-opened the MBA lid, and the same error message "The disk was not ejected properly" occured. I repeated the steps for a few times (thinking my flash drive might be faulty) and at my last attempt, the flash drive was stopped detected. I tried several USB flash drives and external hard drives (of various brands) to both the USB ports of my MBA, only the external hard drives were detected (on both USB ports) and functioning. None of the flash drives was detected on either USB port.
The tested flash drives were plugged to another 13" MacBook (Unibody, Late 2008, OS X Lion) and they all worked fine.
I wonder if anyone faces the same problem, and solution(s) please?
Additional: OS X Mountain Lion re-installed and same problem occurs / No problem with OS X Lion.

I had the same issue after installing Mountain Lion from the App store. The issue is you are missing the IOUSBFamily.kext extension amongst others. The solution is to backup your macbook, then perform a clean install of Mountain Lion.
I had this done at the Apple Store and now everything is restored as well as performance speed being improved.
Note: When restoring your files (a clean install will delete all your files and applications), use the Migration Assistant.
I would recommend going to the Apple Store to do this because they can perform the clean install from a USB which is so much faster than the download form the App store.
Hope this helps.

USB Flash Drive not readable using 10.4.6 but is with 10.3.9

I noticed that a 32MB USB Flash Drive that used to work on my Powerbook when it was running 10.3.9 became unreadable when I upgraded to 10.4.6. This flash drive still works on my Dell WinXP system and I just tried booting the powerbook off a clone of my 10.3.9 setup (on an external firewire drive) and my flash drive works on that. So it appears to me that 10.4 has introduced a software bug that has disabled support for some flash drives. I will note that I also use a USB compact flash reader for transfering digital pictures and that does work under 10.4.6 so the problem does not affect all USB flash devices.
Is Apple aware of this? Are they working on it?
PB 1.5 GHz G4 15 Mac OS X (10.4.5)

Have you tried to open it in disk utility? Probably won't, but worth a shot. If not and you don't know who made it, then I'd say your out of luck. Probably time for a new Flash drive.
A 32meg Flash Drive today is very cheap if you can find one. You can get a 250 meg Flash drive for $20-$30. That's 8 times the storage you have now.

USB Flash Drive not geting detected

I brought HP x705w 16GB USB Flash Drive in the month of October 2014. It is not getting detected in any computers i tried. I tried from DEVICE MANAGER but same problem NOT GETTING DETECTED. It is under warranty period.I visited HP care service near me (Aurangabad) but they are not helping me. Please give some help regarding this problem.

External USB Hard Drive Not Recognised / Seen

Hi,
I have a WP 250 GB External hard drive which was working fine until recently and now is not recognised by my 2007 Intel Macbook. When I plug in the hard drive, a light comes on solidly and it begins whirring. Then, it continues to whirr as if it was going to work, but the light starts flickering.
It is not visable as an external hard drive in finder. 'View Hard Disk' is switched on under Finder / Preferences. On System Profiler, when I click 'USB' fom the list on the left, the computer displays the circular "thinking about it" spinning thing, and system profiler freezes, and nothing else happens. The same thing happens with disk utility.
I tried plugging the hard drive into a windows computer, and it worked fine; all the files inside it were visable. It is formatted to my mac and I have successfully used the hard drive many times before. A logical next step would be to try it on another mac but I don't have access to one.
I have tried to to a PRAM reset, but couldn't do it, even following the instructions on the MAC website (turn off computer, turn on and hold the mac button, ctrl, p, and r simultaneously) it wouldn't do a PRAM reset.
I am not a computer expert, but I am not completely green either. Why is it that doing the simplest thing on a computer requires a minimum of a 4 year computer science degree or equivalent.... somebody please help me crack this, I am close to smashing the whole thing to pieces with a hammer (which would be satisfying but counterproductive and expensive...)
Thanks in advance for your replies

Did you allow Windows to upgrade the formatting on this drive from FAT to NTFS recently? You should be able to check the formatting on the volume from within Windows. It would also be worth trying to repair the drive under Windows if it allows you to.
Note that NTFS is not readable under OS 10.4.x without special software. NTFS is read-only but not writable under OS 10.5 and later.
If the volume isn't NTFS, and repairing it doesn't help, you may need to just backup the data and try to reformat it.

USB flash drive not recognized by computer. Have tried all options of which I can think.

Okay. I have a Patriot S-Mini 32GB flash drive that my Windows 8.1 HP Slimline 400-434 is not recognizing. I believe it recognized it once, and has refused to do so since. My laptop (Windows 7 Toshiba) recognizes it just fine.
All other USB devices function perfectly on this computer. USB mouse/keyboard/USB Hub/Apple iPhone cable.
1. I have tried unplugging all other USB devices before trying this one. FAIL
2. I have gone to Device Management and the USB drive does not appear in the list. FAIL
3. I have uninstalled the USB Root Hubs and restarted the computer. FAIL
4. I have tried plugging the USB drive into the rear ports that plug directly into the motherboard. FAIL
5. I have updated the drivers, and have been unable to find a BIOS update as the link on the HP website downloads and says that it is incompatible for my computer. FAIL
...so what the bloody gorram heck do I do now?
This question was solved.
View Solution.

Okay, and in the most ridiculous way I have ever solved a technical problem...
The USB flash cannot be inserted ALL the way into the port. It has to be inserted slowly, so that the contacts line up.
I figured this out by trying to connect it into my USB hub and noticing that the red indicator light was going on and off as I inserted the USB drive, flickering on as I inserted it and then off once it was all the way in.
Weird. But hey. It works now.

USB flash drive not being recognized as a startup disk?

Hi everyone, I've been searching for similar questions but haven't found one that exactly matches my experience. So, I'm going to try and explain my issue in hopes that others may be able to help.
I'm trying to create a bootable flash drive from which I can install lion, and eventually Mountain Lion when it is released onto my main hard drive. My main reason for doing this is to have a way that I can perform a clean install of the operating system. Yes, I know I am old fashioned, but sometimes I prefer clean operating system installs rather than upgrading. In any case, I have downloaded the lion setup file from the Mac app store (Install Mac OS X Lion.app) and am following the directions given on this page to do this procedure. These directions are consistent with directions found on various other sources online. Having this file saved to my hard drive, I was able to find and extract the disk image file from the package InstallESD.dmg to another folder. Once extracted, I plugged in my flash drive and attempted to use disk utility to restore the disk image to my flash drive. I selected the dmg file as my source and the flash drive as the destination. I then clicked restore and was warned that all data on the flash drive would be erased while the disk image was restored to my flash drive. I was prepared for this, so I allowed the process to continue, and it appeared to proceed with no problem. When disk utility was finished, I did a quick look at my flash drive using finder and confirmed that it did in fact appear to contain a disk image of the .dmg file. Here's where things get interesting however.
When I go to system preferences and choose startup disk, my flash drive is not listed as an optional disk from which to boot, only my hard drive ("macintosh HD"). When I restart and hold down the option key, my flash drive is not listed as a startup disk either. I know that the non-intel based macs are not capable of booting from USB, but this is certainly not my issue as I have an intel macbook pro, mid 2009 model. My flash drive is about 4 or 5 years old; it is a PNY Technologies Attaché 16 gb flash drive. I have no trouble viewing and transferring files to and from the flash drive, the only issue is that my computer seems to refuse to recognize it as a startup disk. Are there certain flash drives which do not support booting? This would normally seem more like a computer issue rather than a flash drive issue, but most people seem to have no problem doing what I'm trying to do. Unfortunately I do not have another flash drive with which to test this, and I didn't really feel like buying another flash drive just to test this out if in fact this is not a flash drive issue. I am planning to upgrade to the macbook pro retina soon which of course does not have an optical drive, which is one of the reasons I would like to get this working. Can anyone think of something else I can try? Is it more likely an issue with the macbook pro or the flash drive?
Thanks in advance for any thoughts.

The format says Mac OS Extended. All of the settings were set during the disk image restore process. Even if I format the flash drive as extended journaled or some other format, all of these settings are reverted when I do the restore from the disk image. I will just copy all of the information that disk utility has so that you can see it.
Mount Point : /Volumes/Mac OS X Install ESD Capacity : 16.11 GB (16,106,110,976 Bytes) Format : Mac OS Extended Available : 12.3 GB (12,303,499,264 Bytes) Owners Enabled : Yes Used : 3.8 GB (3,802,611,712 Bytes) Number of Folders : 128 Number of Files : 876

USB flash drive not recognized on desktop or disk utility

I see a number of similar threads to this but nothing solves this problem. Any help will be greatly appreciated as I am about to go crazy!
I have 3 USB thumb drives that all worked 2 days ago - now only one does. I have tried all drives in multiple ports and the same result. I have restarted the iMac (2009 Yosemite) a number of times and the same result.
This came about attempting to create bootable USBs with each of these. I was struggling with the process on my mac so took 2 (brand new 16GB PNYs) to a PC created the live boot USBs and they booted fine on the PC (knowing this wouldn't boot my mac). I did however plug them into my mac and they were recognized. I finally found success creating a Ubuntu live boot with my old USB. With that success I wanted to try with one of the new USBs on the mac.
Here is what I did:
1. Using Disk Utility - Reformatted the drive 1 partition MS Dos FAT 32
2. In Terminal unmounted the drive and ran a dd command to copy the linux .img file successfully
3. Box came up saying drive not recognized and selected to ignore (this happened on my old one that still works also)
4. Ejected drive from terminal
5 Restarted mac and attempted to boot from USB without success.
After this the 2 new USBs were no longer recognized in any usb port while the other still is. They do not show on the desktop nor in Disk Utility. I checked them on the PC and they are still both recognized and showing the FAT 32 format.
Help please!

Thank you for the reply. I found some time to go through this process a number of times without success
Any other suggestions?

Usb flash drive not working in iMac

PNY 128gb flash drive is not working in my iMac when I tried to copy.

Did you partition and format it?
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
