External mass storage device doesn't appear in the finder

When I plug either my camera or my iPhone into the USB port I get a message saying 'no camers was found' and the device doesn't appear in the finder. I can see the phone in iTunes and the camera in its own Canon software, but I can't access the device and manage the files via finder. Getting annoying, have to delete stuff off the camera manually one file at a time. Why don't these devices show up in finder? Using Macbook Pro running Lion, iPhone 4 with iOS5, Canon IXUS 100 IS.

USB external mass storage devices doesn't work.

Hey guys,
I couldn't find any answer to my problem so I hope you can help me...
I have USB Seagate external USB drive which was working perfectly with my mac until I installed VMware. The thing is that since first time I installed XP on VMware and unmounted my external drive from OSx and mounted in for virtual machine the drive is no longer visible in Mac OS no matter if I unmount it from virtual machine, plug/unplug from port, turn off VMware, restart macbook in any possible sequence combination. However I can use it easily in virtual machine or on other PC. Problem is not files type related, because I've already checked it, what is more I didn't format the drive and earlier it worked.
What is more now I can't even see my pendrive despite the fact that both Seagate drive and pendrives are visible in system profiler. My USB mouse works perfectly so problem apparently is only with data storage devices.
During the installation an error pop up concerning "IOUSBMassStorage" file but after installation of VMware everything was working until I mounted in on virtual machine.
EDIT: I almost forgot to add that I uninstalled VMware and the problem still occurs.
Thanks for any help in advance.

I was trying to install update USBFamilly and now also VMware again and in both cases I get error saying that USBMassStorageClass was installed improperly.
I found few topics about this file on the internet that it controls exactly what I have problem with but couldn't find solution for how to reinstll this file.
Any ideas ?

IPod doesn't appear in the finder nor on the desktop when connected

Hi,
My iPod touch 2nd gen doesn't appear in the finder nor on the desktop when connected, is it normal maybe because its a flash drive and not a harddrive, I don't know...
By the way, everything is normal with iPhoto and iTunes.
Sincerely

The Touch and iPhone do not have disk mode, that is why you can't see it.

My iPhone doesn't appear in the finder

When I connect my iphone to my computer it doesn't appear in the sidebar. How to solve this problem?
thanks by advance for your answers!!

It shouldn't appear in the finder sidebar, only the iTunes one (and iPhoto too).

My flash drive won't appear on my iMac; "Devices" doesn't appear on my Finder.

The Support information posted so far doesn't help; Finder does not bring up any external devices at all (Printer, Time Machine, flashdrive).

Have you set Finder preferences to show external disks?
FWIW, I've not seen printers showing on the desktop and know of no way to set it up to do so.

Time Capsule vs. Other Mass Storage Device

I am a Mac newby seeking advice. I recently purchased the MBA below to replace my personal PC. My previous setup was a desktop with plenty of storage to handle my needs (including iTunes) and I backed up data directly to an external hard drive (I know pretty basic).
After purchasing the MBA, I realized I do not have enough internal hard drive space to store all of my music and my current external drive is too small for all the media and backup of the MBA. Also, the point of the MBA is to be mobile. Also, I would like my Sonos music system (with an application similar to iTunes) to be able to access the music library. Lastly, I have far to many songs purchase outside of iTunes to use iTunes Match. Therefore, I started seeking wireless alternatives to store my music and backup my MBA. Although an NAS would probably be ideal, I have found out through trial and error that the basic systems do not work with a MAC and the only ones with a prayer are the more expensive ones (i.e. Synology and QNAPS). Therefore, I have decided to pursue a more simplified approach.
My Internet and TV provider is CenturyLink. Their router is very basic with only 802.11g speed and without any USB ports. The following configuration has been suggested to my by some more experienced Apple users to provide wireless data access and backup.
Requesting CenturyLink provide me with a basic modem.
Purchasing an Airport Extreme (or similar wireless n router with a USB port).
Connecting the Airport Extreme (or other wireless router) to the basic modem.
Purchasing a Time Capsule (or other mass storage device).
Partitioning it using either the specific one for the Time Capsule (or Disk Utility for other mass storage devices) to provide one volume for my media and one for backup using Time Machine.
Moving the media from my old external drive (which is catalogued with folders for each artist, subfolders for each album and the songs in the subfolders) by connecting the old mass storage device and Time Machine to my MBA and using Finder to do this (see the questions below regarding this).
Moving/cataloging the media from the Time Capsule (or other mass storage device) by dragging it into the iTunes window.
Connecting the Time Capsule (or other mass storage device) to the USB port of the Airport Extreme (or other wireless router).
Setting up Time Machine to use the volume partitioned for backups.
Possibly having to move cataloging files from my iTunes, Music folder to the external drive and pointing iTunes to the Time Capsule (or other mass storage device) through Preferences, Advanced to access the music.
Overall, I am concerned with the total cost. I just spent a lot of money, not only purchasing the MBA, but also the iPad 3 and upgrading my cell phone to the iPhone 5 (I skipped the 4). It seems that by the time I purchase an Airport Extreme and a Time Capsule, I could also have just bought a NAS like the Synology 213 with 2 X 1TB drives, connect it to the existing wireless router via ethernet connections and have a more comprehensive solution. Based upon these instructions and cost concerns (and bad experience), I have several questions related to this.
Does this configuration and these instructions make sense, including those for moving and accessing my music files through iTunes (i.e. will it work)?
Are both the Airport Extreme and Time Capsule necessary to make this work easily or can I purchase alternatives to either or each and if so, what is recommended? If they are necessary, would you recommend doing this or buying one of the aforementioned NAS's to a Mac newby?
Given the file structure for my music on the old external mass storage drive, can I simply move the folders over with the subfolders containing the musice files in them or do I have to literally enter into each subfolder, select all and move them subfolder by subfolder (i.e. album by album)?
Am I missing something totally better and easier solution?
I would be massively grateful to anyone who can provide some good answers, advice and guidance. I am about to pull my hair out!!!!
Thanks,
WinoSkiBoy

They both said about the same thing except the Apple Store business tech said to buy an Airport Extreme and just attach a partitioned external third party HDD to it.
Except that is flakey for TM backup..
http://pondini.org/TM/Airport.html
And slow as the proverbial dog.. although I guess the dog is old.
And totally inadequate as a media store or server.
Apple's pricing is pretty cunning.. I really doubt you are going to find a cheaper unit to do both wireless and TM backups than the TC. And it is a perfectly good device to do that. It is good to have in the network. And Apple sure make their products work with other apple products.. so it does work better than other similar cost products.. although you miss a lot of features that Apple predecided for you.
But I don't think anyone has the ideal solution to your problem. Apple believe in cloud. And if you have fibre internet that will work really well.. forks out your money and apple will store your stuff. But for the real world most of us do not have internet connection even a fraction of speed required. And it can be another decade before we will. We need a box that is half way between a TC and media PC, a file store and a NAS. Will Apple make one.. ?? I don't think so.. They believe in cloud..
You can make the missing link one yourself. If you are so inclined.. A HP microserver running freeNAS can do TM backups and makes an excellent media store because it can do AFP. You can put a graphics card in it and plug it into your TV. You can use it with a airport extreme. But you will need a degree in Geek.. !! The synology is a preconfigured form of that.. No Geekdom required. Synology seems to have the upper hand.. this week.
Let me make a suggestion.. Figure out if you are going to jump into the Apple way of doing stuff.. which is basically itunes on computer as a server.. and the whole network.. working as part of this.. so any media is pushed from a store in itunes.. whether local or internet.. if you want to do it that way.. getting something other than the air to run itunes is well worth it. That is what a NAS cannot do.. it cannot be a media player.
Or you do hybrid.. ie you don't use put all your media into itunes, you use a bit of this and bit of something else.. As long as that can play files.. stored on NAS or even on the TC without the itunes requirement.. It won't be as pretty. But it isn't hard to get working.. as long as you accept this isn't going to be the perfect Apple solution.

thanks Scott

Hey poochokid,
I'm sorry you're running into this issue. For the camera, if it's newer (made in the last 3 or 4 years) you may need to go to the Nikon website and find the camera software that is made for Vista. I could try to help you find that, if you could give me the model of camera you have.
For the Microsoft WPD file system volume driver issue take a look at this thread from another forum.
I hope this information helps! Let me know what the results are

ITunes recognizes other mass storage devices/network but not iPod

When I plug my iPod into the computer, Windows and iTunes recognize that the iPod is connected. A windows bubble from the sys tray tells me that a mass storage device was detected, and a iPod icon appears in iTunes. However, iTunes does not connect to the iPod; for some reason it connects itself to the network (ethernet connection) or to my external hard drive (USB connection), in that order. It will recognize the network as the iPod, unless it is disconnected, and then it will recognize the hard drive as the iPod. If neither of these devices are connected, then the computer doesn't recognize the iPod at all unless I restart it. Thus, to get the computer to recognize my iPod, I have to disconnect my network, and my external hard drive, restart the computer and plug in the iPod. After this point, I can reconnect both devices and everything works. What's going on?

hi ephmike!
that sounds like classic symptoms of a Windows drive letter confusion problem. let's see if this document will help:

USB Mass Storage Device won't Eject/Unmount

My brother bought a Sanyo ICR-B180NX digital voice recorder last year to use with his iBook. It was working very well up until about August of 2005. At that point, the recorder would mount on the desktop, and he could get all the files off (it records direct to MP3 format rather than WMV, so he can edit his files very easily), but when it came time to eject it, the device icon would disappear and then immediately re-appear on the desktop. The display on the voice recorder remained static at the "Connect" screen.
I believe this happened in conjunction with some sort of OS update, as it was a "sudden" thing. We can't quite recall what happened between the times it worked and the time it stopped working.
I have tried the device on a PC, and it works the way it should, so I don't believe there's anything wrong with it.
Now, I know the system requirements on the website say that you must have Windows, but a statement from a support company (we returned it to the place where we got it, and they sent it out for repairs, and it came back with a letter) states that the device does act as a generic Mass Storage device, and thus may work with most systems.
All my other USB storage devices (ie. SanDisk 12-in-1 card reader, SanDisk Cruzer Titanium 2GB, iPod Photo), and FireWire devices (ie. WiebeTech TrayDock Extreme) work fine and unmount fine.
Does anyone know of any changes to the way Mass Storage devices are ejected in the current iteration of the OS? I haven't had a chance to test the device under an older OS, but will soon.
Alternately, if anyone has any suggestions regarding replacements (not really looking forward to that, given this recorder cost almost $300CAD), let me know. We need a device that can plug in via USB and transfer files to his iBook which he can edit together (he's a newspaper reporter in training, and needs to edit the interviews to take out such things like dead air, etc).
Thanks!
Mike Ma.

Hi
+USB mass storage device. An error occurred during the installation of the device the data is invalid+
This typical error message appears if the installation of external USB devices failed.
Why? This is not easy to say
What you could do firstly is to clean your registry using the freeware software called CCleaner (Google for that).
Install it and clean your OS and the registry entries.
After cleaning access the device manager and remove all USB root hubs and all USB Host controllers from the device list and reboot the notebook.
New reboot should cause a new installation of USB drivers.
Finally try to connect and try to install your external USB devices again.

PCI USB Card Does NOT Work With Mass Storage Devices

I have a StarTech PCI card with 6 USB 2.0 ports that I inserted in my 500 MHz (overclocked) B&W Power Mac G3. It works great for any USB device EXCEPT for any hard drive or DVD/CD-RW drive. I checked the system.log file for errors. Nothing shows up in System Profiler or Disk Utility, obviously. Here's what it consistently says:
Dec 16 23:33:28 Geoff-Myers-Power-Mac-G3 kernel[0]: USBF: 674.997 [0xf9c000] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 6 of hub @ location: 0x62000000)
Dec 16 23:33:33 Geoff-Myers-Power-Mac-G3 kernel[0]: USBF: 679.977 [0xf9c000] The IOUSBFamily was not able to enumerate a device.
I'm running the latest version of Mac OS X Tiger 10.4.3. What is wrong? StarTech doesn't have a driver, but nothing should be necessary. Is there a 3rd party USB Mass Storage Device driver that might work better than the Apple generic driver? PLEASE HELP ME! I cannot live with USB 1.1.

Some users have reported problems with certain brand cards and their controller chipsets, so trying a different card may resolve the problem. Keyspan and Macally are often mentioned as being more "Mac-friendly" than some other lessser-known brands or generic cards. Does the card have a mini-power port to supplement the power requirements? With USB 2.0, each port is on a separate bus, so a card with six ports should have one. To minimize the overall draw on the available power, I prefer to install USB cards with as few ports as are needed.

Can I use iCloud like a mass storage device - pc free

I am living on a boat and I am using my iPad w a camera connector kit. Can I back up photos that won't all fit on my iPads internal memory(16G), using iCloud like an external hard drive? I don't have a pc w me and don't want one.

With iCloud and photo stream your photos are automatically syced to the cloud, but the photos will only stay in the cloud for 30 days which is enough time by Apple's standards to download them from the cloud to a mac or pc so I guess the answer to your question would be no, you cant use iCloud as a mass storage device.

USB Ports - Mass Storage Devices - Unknown Device

Model: Satellite A135-S2276
OS: Vista
I recently tried plugging in my media card reader that I've had for several years now and has worked many dozens of times. Windows responded with an 'Unknown Device' response. I thought this was odd, so I changed and tried each USB port. To no avail the device wasn't recognized. I tried it in another computer and it worked fine.
I began to try two other mass storage devices that I know used to work, up until recently, on the laptop. Both now are 'Unknown Devices'. I now have a strong feeling that someting was wrong with windows vista. So I search around and find methods to force the driver (inf) cache to reset which should reload any corrupted drivers. Tried many methods, nothing worked, same results. I saw that Vista Service Pack 2 just came out, I installed that hoping that it would fix. Nope.
I gave up on it being a software issue after I did a fresh reinstall of the OS and with the base OS with no other software installed same results.
Is there a way to diagnose if the USB is malfunctioning from a hardware standpoint? Is it possible the USB, even thought windows recognizes it, is dead on the motherobard? If so, how do I get this fixed? Motherboard replacement?
Help!!

It sounds like it is working enough that it can recognize that soemthign is plugged into it.
You say you did a fresh install of Windows. Did you use the recovery disk or a retail Windows copy. If oyu didn't use the recovery disk then maybe you are missing a driver. Best woudl be to use the recovery disk. If a USB mouse doesn't work after that then the hardware has an issue. Assuming the BIOS is OK.

How do I get it to be read as a mass storage device?

I've read all of the step by step processes on viewing my ipod touch (3rd generation) to be viewed in "My Computer" as a mass storage device and then viewing the files and putting music on that way, or taking the music on there and putting it on itunes, abd it doesn't work. I can't seem to get my ipod to be viewed as a mass storage device! My OS is windows 7 and please help!

An iPod touch never had that capibility.

PC won't recognize BlackBerry as mass-storage device.

I have a Curve 8320 with a 4-Gb SanDisk micro SD card. Due to difficulties installing BlackBerry Media Sync, I'm trying to just manage my media (music, no photos or videos at the moment) simply by using my BlackBerry as a mass-storage device. I understand that when I connect the BlackBerry to the computer with the micro SD card in it, the BlackBerry is supposed to prompt me to enable mass-storage mode. However, this is not happening. I can't get the BlackBerry to appear as a mass-storage device in the Computer folder on my PC. I can tell the BlackBerry is indeed interfacing with the computer, for Desktop Manager is able to interact with it. I've gone into the Media Card option in Options and enabled media-card support and mass-storage mode and told the BlackBerry to auto-enable mass-storage mode when connected, and I've formatted the card with the BlackBerry as well, but still I've had no luck.

Hi and welcome to the forums!
A couple of places for you to visit: Blackberry 101 Tips & Tricks
Take a look at this kb article: Unable to view media card
If that is not the issue, you might also want to use DM WITHOUT Media Manager as it may be causing the conflict:
I suggest the following steps (insert plenty of reboots of your PC...not just restarts, but full power down reboots). Also, it is advised that you be logged into the PC on an account with full admin rights. Further, under Vista, use the "Run As Administrator" option for everything.
1) Cleanly uninstall the RIM DTM software:
KB02206 How to perform a clean uninstall of BlackBerry Desktop Software
2) Get a fresh download of the RIM DTM software:
Software Download for Blackberry Support
* Choose the version that is newest and (if applicable) compatible with your PIM (if you are synchornizing via USB):
KB12268 Applications supported by BlackBerry Desktop Manager for synchronization
3) Install DTM to your PC
4) Start the organizer configuration over:
