OS X not reading USB drives, iPhone

I have recently installed Snow Leopard and some IOUSB updates (I'm leaning towards IOUSB being the issue) and now OS X does not recognize any flash drives or iPhone when I hook them up. (If I run Windows via Fusion everything works fine - and yes I have quit fusion and still doesn't work).
Any suggestions on how to get this working?

Here's a USB faq.
Some of Apples tips.
Sometimes a PRAM reset will help.

My new mac mini does not see usb drives, but in hardware info the usb is visible

my new mac mini does not see usb drives, but in hardware info the usb is visible
i'tried several usb flash drives even brand new ones, they are visible onder hardware info but they are not on the desktop nor in the finder.
what is wrong and doe anyone has a solution ?

It does not show up in disk utility, its only visible through systeminformation.
When you plug in the USB flash drive and then refresh systeminformation it becomes visible.
To remove it I shut down the computer because I cannot eject the USB device anywhere.
After starting up again when I have removed the flash drive it has gone from the systeminfo USB list.
By the way my USB mouse and keyboard are working fine, I also changed ports of these and they still keep on working so I don't think the USB ports are defect.
I guess it some kind software problem, and because I'm new to Apple I do not know much about it how to solve this.

Airport Extreme will not show USB drive installed Solved!

Airport Extreme will not show USB drive installed Solved... At least for me!
Here's what I had to do to make it work with the newest 7.3.1 firmware.
Ready for this? No Joke Really!
1. Connect your USB drive to the Airport Extreme.
2. Turn it on.
3. Open the Airport Utility.
4. Go to Manual Setup.
5. Choose Disks and File Sharing.
Yep, we are going to set file sharing before we even see the disk we want to share!
You (I) had to set File Sharing on and Share Disks over Ethernet checked as well as set the Work Group (In my case). THEN restart the Airport Extreme.
After it re-started... My USB Drive was now present and ready for use.
I also dis-allowed Guest access. I re-started ALL computers in my network, both Windows and MAC. The USB drive held and works GREAT!
I know... Most of you thought this was a joke, It's not!
I tried everything to get the USB drive to work and failed every time just like most other people. Doing it this way worked like a charm.
Go Figure huh!
Hope this helps someone with this issue.

How was the usb hard drive formatted? Was it NTFS, FAT32, or HFS+?

The name of my wireless network in the form of my modem router is not read from the iPhone, while the first era.Il my ipad does not read the network but I surf the internet. Why? What can I do?

The name of my wireless network in the form of my modem router is not read from the iPhone, while the first era.Il my ipad does not read the network but I surf the internet. Why? What can I do?

Can I use this DIR-635 to extend the WiFi network of the "Belgacom" WiFi?
To answer this question correctly, a user would need to have a DIR-635 router connected by Ethernet to a Belgacom router.
If you think about it, the chances of another user who has these two same devices configured this way and also being on an Apple support forum to see your post are about zero.
The following might work, but you will not know until you try.
Configure the DIR-635 to provide a wireless network that uses the exact same wireless network name, exact same wireless security and exact same password as the Belgacom wireless router. Make sure that the DIR-635 is configured in Bridge Mode.
Can I purchase and set-up an Apple Airport Express or Apple Airport Extreme on my level 1 (the ethernet cable running from level 2 to level 1 could plug-into either of those)
The AirPort Express or AirPort Extreme would need to be configured exactly the same way as mentioned above.
(What is the difference in the 2 -- one is about twice the price of the other…)

I have an imac 2009 the disk drive is damaged and I have lost the passwords I need to reset passwords I tried booting with a macosx disk from an external hard drive but did not read the drive how else can I reset password ?
I have a 2012 mac book pro can I use that to connect with firewire and load osx that way? and how woudl I do that?
Thanks so much!

To what password are you referring? Do you mean your user account's admin password? Or do you mean the master password for File Vault or do you mean a Firmware Password?
For an admin password:
Forgot Your Account Password
For Snow Leopard and earlier
     Mac OS X 10.6- If you forget your administrator password
For Lion/Mountain Lion
    Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     When the menubar appears select Terminal from the Utilities menu.
     Enter resetpassword at the prompt and press RETURN. Follow
     instructions in the dialog window that will appear.
     Or see Reset a Mac OS X 10.7 Lion Password and
     OS X Lion- Apple ID can be used to reset your user account password.
If you cannot do the above then try this:
1. Boot to Safe Mode by restarting and after the chime press and hold down the COMMAND-S keys until a black screen with white type appears.
2. At the prompt, type the following commands pressing return after each command line:
     /sbin/fsck -yf
     If you do not receive a "Filesystem OK" message then repeat this command until
     you do. If after seven tries you still do not receive a "Filesystem OK" message,
     then the system is corrupted and needs to be reinstalled.
     mount -uw /
     cd /private/var/db/netinfo
     mv local.nidb local.old
     rm ../.AppleSetupDone
     shutdown -r now
The second-to-last command above will cause OS X to think that the operating system is newly installed, and when the new owner starts up the computer it will send him/her to the startup wizard where he/she can start a new user without reinstalling.
This last method does not actually change a password. It simply removes the user accounts and lets you create an initial admin account as if the computer were new out of the box.
How to reset the OS X password without a startup CD:
Reboot into Single-user Mode. Enter the following and press RETURN after each command line
   1. Type fsck -fy
   2. Type mount -uw /
   3. Type passwd <username>
I have never tried this method myself.

My MacBook is not recognizing USB drives, but it recognizes my iPhone. Can someone assist me? Thank you.

I am trying to get my mac book to recognize the thumb drive. When I go into Disk Utilities it does not show up there either. I have no problem syncing my iPhone to it so I do not think the USB drives are bad. Can someone help me out? Thanks!

I am getting the same issue with my MacBook Pro. If I go for a long peroid of time without restarting it starts to 'forget' USB sockets. First one stopped wortking and then the other. I restarted and they both beagan working fine again. Try giving that a go - I know it's an obvious option but it worked for me.
Otherwise check the file system on the thumb drive - is it Mac compatible? FAT 32 for example? Does it show up on other computers?

I noticed you said "drive", and not disks. You do know that nothing happens until you load a disk into the drive, right?

Hi All,
Looks like it was a driver / incompatibility / unsupported issue since 2 other much smaller USB keys (Lexar USB Flash Drive – 32GB, SanDisk Cruzer Colors – 4GB) were successfully mounted automatically by volfs service as follows:

Macbook Pro will not read G Drive

I bought a 2 tb G Drive about a year ago and was using it on my previous laptop which got stolen. I want to use my G Drive with my new laptop but for some reason it is not reading it. I tried everything. I looked for it in disk utilities also and it does not show. SOMEONE HELP!!!!!!!

- Is it connected via USB?
- Have you tried another cable?
- Is the HD AC power (vice powered by the connecting bus?
- Can you feel.hear the drive spinup?
- Go to System report and see if the enclosure and HD show up? If USB is is under USB
- Have you tried on another computer?
BTW, this is Mac Pro desktop forum

Usb drives are not working, usb drives are not working

USB drives are not working. Please help

Non of my Western Digital drives are working anymore on several different Mac computers, one Mac can still work with the drive so I am not getting it up dated to the new OS.
If they told me that all my 2 TB drives would no longer work if I got the new OS I would not have updated.
There needs to be a fix, I can't afford all new drives plus they have video on them that I need to use.
Also iPhoto and Garage Band have disapeared I can't find any trace of them???

[SOLVED] BIOS not detecting USB Drives after i installed Arch

SOLVED: In BIOS under 'Advanced' disable 'Fast BIOS Mode'.
Original post:
Hi there!
I'm fairly new to the arch (and linux) scene and just setup my Samsung 530U3B with a brand new installation of arch. Everything went fine and the system is running flawlessly. Almost.
I just happend to notice that BIOS is not checking for USB drives anymore, it just somehow skips that part. If enter the boot selection, the bootable USB drive won't show up. Neither does it show up in BIOS setup. I tried to boot with the same USB drive that i used to install arch just yesterday, the live media does not boot - the drive doesn't even blink. The boot priority is set to usb drive first, the boot selection screen (hammering f10 during boot) doesn't give me any other option than to boot from the normal SSD. Also, prior to the arch installation (came with w7 installed) the BIOS screen would stay for about 2seconds and then proceed to boot - this doesn't happen anymore. When i press the power button greeted by the grub bootloader in about 1s.
I tried 2 different usb drives, both with the arch iso (same that i used to install the currently running OS, downloaded yesterday). The drives also show up once my arch is booted (starting to blink just after i hit enter in grub). Also, both drives boot without a problem on my desktop computer.
Anyone got any ideas?
I don't really now what kinda of information would be helpful so i'm just dumping stuff i know:
BIOS: Phoenix SecureCore Tiano Version 04XK
Machine: Samsung 530U3B
SSD: Samsung MZ7PC128HAFU-000
ISO used to install (checksum ok): archlinux-2012.07.15-netinstall-dual.iso

Welcome to the forum.
If you just set the USB stick to be first in the boot order, the next option (from the list) takes its place the moment you unplug it. You need to set the BIOS to boot from your equivalent of "Removable Devices" first, "Internal Drives" second and "Optical Drives" third.
The USB stick doesn't show up at all. I set the priority as follows:
1. USB HDD
2. USB FDD
3. USB CD
4. SATA CD
5. SATA HDD
6. NETWORK
I used that same configuration to install arch. USB doesn't seem to initialize at all. Also, if i enter "usb" in the grub commandline, no devices are listed.
Thanks!
UPDATE:
I just figured it out. In my BIOS under 'Advanced' the 'Fast BIOS Mode' was enabled, once i disabled it, everything went fine. I don't remember changing that option. Silly me.
Sorry for your time

New Airport Extreme (2014) does not see USB Drive

Just fired up my new 2014 Airport Extreme and attached a Toshiba 3 TB USB Drive. My new (late 2013 iMac) does not see the new drive in Disk Utility.
The Extreme works in all other ways; ie, as a router, as a wireless node.
It came to me formated as a Windows drive, so I attached it directly to my MacBook Pro (which saw the drive) and reformated it as a Mac Drive (Journaled, GUILD). It showed up just fine on the MacBook Pro desktop.
When I reattach it to the Airport Extreme, it still does NOT show up in Disk Utility on the iMac.
Help Please

When I reattach it to the Airport Extreme, it still does NOT show up in Disk Utility on the iMac.
That drive will not show up in Disk Utility on the Mac.....since the Toshiba hard drive becomes a network drive when it is attached the AirPort Extreme.
Disk Utility will not display a network drive. It will only display drives that are connected directly to your iMac via USB, FireWire, etc.
Check using AirPort Utility to see if the AirPort Exteme recognizes the drive.
Open AirPort Utility, click the AirPort Extreme icon, then click Edit
Click the Disks tab at the top of the next window that appears
The drive will appear here if it is recognized by the AirPort Extreme.
In the example below, my WD Drive is connected to the USB port on the AirPort Extreme.

Mac Pro - Reads USB Drive only in Windows

For the past couple weeks I have been sharing 'Word' documents on a USB drive using both Windows and Mac OS platforms. A couple days ago the Mac side of the computer stopped recognizing the USB drive. It does even show the drive on the desktop. I tried putting the drive in the other USP port. This didn't help. When I turn on the Windows side, using XP, the drive works fine.
Am I doing something wrong? Can I use the same USB drive to share files? Or, do I need try another way to share files between platforms?
If this doesn't work, I was thinking of putting my files on Google Documents and accessing almost everything via the Internet.

I recently had the reverse happen to me. I had a FAT formatted flash drive that I would frequently put into a device that needed non-Mac. I also used to use it a lot with Windows - Mac transfers. Plugged it into a Windows computer and it said it needed formatting. The only think I can think of is occasionally something gets written to the drive in a form that the other system can't handle. I'd copy off any files that are valuable then reformat the drive to FAT and see if it then works.
