USB Drives mount become a device

My usb flash drives have random decided to not become a device. Basically I put them in, and they get recognized but not deviceified.
Some info:

Sorry about the links. I couldn't figure the url function out.
Thanks for your help

I don't know, but I had http://wiki.archlinux.org/index.php/HAL open and it says:
There are a number of factors involved in 'hotplugging' and HAL is only one of them. When a new device is added, e.g. a USB drive is plugged in, the following occurs (roughly):
* The kernel becomes aware of a new device and registers it in /sys.
* Udev creates a device node (e.g. /dev/sdb1), and loads the drivers/modules needed.

You need to completely uninstall iTunes from your computer and then download and install it again.
You do know that Microsoft has a web site, right?

All USB drives mount as read only for user

I have searched a bunch and thee results I find seem to be irrelevant to my situation. Most relate to a single USB media that is a problem and won't read or write.
On a new Arch install on a new computer (my third base system install). Running Gnome.
All USB mass storage devices mount as read only for the logged in user. Root has write permissions and I can mkdir no problem. It is not an issue with the USB drive itself as this occurs with multiple USB media (I've tested several SD cards on a reader and at least two drives, all the media works correctly on my existing installations)
I'm posting the contents of my /etc/group file in case there's an obvious error there I don't see, and my dmesg output upon plugging in the drive. User name is changed in the group file posted to "archie"
This is a single-user system.

I'm sure I'm just missing something in user management, but I can't find what.

I am also having the same problem. Root can read and write to automounted drives, but my user cannot. I've tried with a variety of drives, I am assuming they are being automounted by root instead of the logged-in user somehow. (I am running x directly, and am not using a display manager, if that has anything to do with it).
When I look at how it is mounted it is as follows:
/dev/sdc1 on /run/media/myuser/drivename type vfat (rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0077,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)

[SOLVED]How exactly are USB drives mounted?

When I plug in a USB drive, Cinnamon brings up the device in Nemo so I can see its files. The location it's mounted at is /run/media/<username>/<long string I assume to be a UUID>/. How is it that I can mount it again at another directory and use it from there? Also, when I unmount it from the second directory, is it already safe to remove it or do I need to unmount it from the first one as well?

I had it mounted at that default location and then I had mounted it onto ~/mnt (I recreated /mnt in my home directory)

I never configured my system to do that. When I used Arch and XFCE, I don't remember USB drives being automatically mounted. I had to do it myself. Cinnamon apparently does it automatically. What I wanted to know was why, if it does it automatically, does mount not give me an error about trying to mount the same partition again in a different place.
Thanks for your answers everybody.

Usb drive mount by a normal user

how can i make a normal user mount usb drives? i added a line in fstab that allows users to mount /dev/sdb1, but this solves only partially the problem

After a recent sys upgrade, I am having a somewhat similar problem. I can still mount my usb stick, but the permissions are now a little screwy (EDIT: i.e. permission denied when trying to change into /mnt/usb directory).
fstab entry:
/dev/sdc1 /mnt/usb vfat rw,user,noauto 0 0
after performing a mount /mnt/usb the permissions on /mnt are:
d-wxrw-rwx 6 root users 16384 1969-12-31 19:00 usb
well, the permissions on this drive seem strange to me, as well as the 1969 date. Additionally if I look at the directory as root everything is executable, which should not be the case. I've added my username to users and storage in /etc/groups to no effect. I can mount fine using pmount, but I would much prefer things my way, plus i dislike the idea of being forced to mount things under /media (notions of liberty and such)
Any thoughts or additional info needed? I've become stumped enough by this odd behavior to actually register and post.

Missing Apple Mobile Device USB Driver Missing From My Device Manager

Hi Everyone, My Apple Mobile Device Usb Driver Does'nt Show up in my Device Manager. But when i go Control panel>> Admin Tools>> Services its there but when i go Start>>Run type in devmgmt.msc an the device manager comes up an under the heading Universal Control Bus Contoller the Apple mobile device usb driver is suppoed to appear but it doesnt all my other usb attached devices do how do i fix this problem?????

For what it's worth. I had the same problem, and here is how I fixed.
I downloaded Roxio Uninstaller and deleted everything Apple. Itunes, Bonjour, Apple Mobile Divce Manager, and Safari, everything get rid of it all. the good thing about roxio is that you can scan for anything that the program uninstaller missed.
Then I down loaded itunes again and Whalaa! It now works.

WD My cloud USB drive mount command???

Hello,
I've a backup script which is autoscheduled and backs up my data to the usb drive. I would like to keep usb drive unmounted until the script starts since twonky scans my usb drive as well and I couldn't disable it from both twonky setup and my cloud UI. After reboot it starts scanning again. (if you know this, it will be a better solution)
So after reboot I would like to unmount the usb disk. I found the unmount command in the forum. Thansk to Nazar.
However I don't know how to mount the drive from the script.
Can you please help me on this?
Thanks...

mount [ -o options,.. ] /dev/sdb1 /path/to/existing/directory or if you know your stuffs let it auto mount on boot, edit /etc/fstab as below, then mount -a or mount /dev/sdb1: /dev/sdb1 /path/to/existing/directory filesystem(i.e. vfat) options(i.e. defaults) backup-dump(i.e. 0) pass-fsck(i.e. 0) Note all above is not supported by WD and warrants warranty void. Wrong fstab entries may not boot up your nas properly so I don't recommend this unless you fully understood. I did a mistake once while mounting additional swap space which end up opening the drive just to recover. Read more https://en.wikipedia.org/wiki/Fstab

"Drive not properly ejected"--How do I keep a USB drive mounted constantly?

I have a 2-month-old iMac, and have had a USB external SATA-enclosure 2.5" 500gb drive attached the whole time. About a week ago, it started randomly giving the "Drive not properly ejected" message and usually it remounts after a few seconds. Sometimes it doesn't and I have to unplug it and plug it back in.
I thought the drive was at fault, so I switched it with a similar drive that was connected to my AirPort Extreme base station. The problem stayed with the Mac. Also I imagined that (somehow) the iMac wasn't supplying enough power, so I bought a powered USB hub. The result is the same.
I don't understand how it can work for two months and then suddenly get this problem. The only change along the line is that about a week ago I did a software update ("About this Mac" says it is 10.6.7). The latest update DOES coincide with the appearance of this problem.
How do I resolve this?
(Notes: There at least one other thread here where people seem to think that this is a Time Machine problem. I think this is because many people connect large external drives for the purpose of backup. I upgraded to iMac from Mac Mini. I installed Snow Leopard right after I bought the iMac and then tried to restore from my Time Machine backup. Something went wrong, so I mirrored my Mac Mini drive onto a 500gb SATA 2.5", put it in a FireWire enclosure and boot from that. I use the iMac's internal 1T drive for Time Machine. That may sound like "lazy man solution", but it could have a great advantage someday where I could plug that FireWire drive into my Mac Mini and not have any downtime should iMac need to be repaired. The random disconnecting of the USB drive doesn't coincide with any Time Machine events. TM is working fine.)

Kappy,
Thank you for your help with this problem!
Your hypothesis for the drive/enclosure being a problem is good thinking, however:
-The problem never existed for the first two months I had the iMac.
-I can switch similar drives with iMac and AirPort Extreme, and the problem stays with the iMac.
-It has nothing to do with Time Machine as I am using a FireWire drive to boot, and the iMac internal 1TB for Time Machine.
-A friend suggested a cable problem, but I have tried many combinations and it wouldn't explain why suddenly after 2 months three sets of USB cables can fail at the same time (at least one, I used for 3 years with Mac Mini.)
I now have a 111gb drive connected to my AirPort Extreme and it has been copying files to my FireWire drive slowly but surely for two hours now. The same drive disconnected after 13 minutes on the iMac. All indications are pointing to OSX 10.6.7. The perfect test (for anyone with convenient resources) would be to install Snow Leopard from disc on a clean Mac and not upgrade it, plug in a USB drive and see if it can last a day or two. Then, upgrade to 10.6.7 and see what happens. I hope someone can try this.
(Is this a ploy to try to sell more FireWire equipment? I hope not.)

Windows 7 64-bit Copying files to external usb drive - files becomes corrupted.

Hi All,
I am getting intermittent problem with regards to copying files to usb external hard drive from my laptop.
When file is copied to external drive, the file becomes corrupt from the external drive.
I have to repeat around 2 to 3 times or more to re-copy the file again until file is not corrupted.
Appreciate of any help.
Below is my system info:

Ok, lets be brief.
This problem is annoying me for years. It is totally reproducible although random. It happens when copying to external drives (mainly USB) when they are configured for "safe removal". I have had issues copying to NTFS and FAT32 partitions. I have
had issues using 4 different computers, from 7 years old to brand new ones, using AMD or intel chipsets and totally different USB controllers, and using many different USB sticks, hard disks, etc. The only common thing in those computers is Windows 7 x64 and
the external drives optimization for "safe removal". Installing Teracopy reduces the chances of data corrpution, but does not eliminate them completely. The only real workaround (tested for 2 years) is activating the write cache in the device manager
properties of the drive. In that way, windows uses the same transfer mechanisms as for the internal drives, and everything is OK.
MICROSOFT guys, there is a BIG BUG in windows 7 x64 external drives data transfer mechanism. There is a bug in the cache handling mechanism of the safe removal function. Nobody hears, I've been years talking about this in forums. It is a very dangerous bug
because it is silent, and many non professional people is experiencing random errors in their backup data. PLEASE, INVESTIGATE THIS. YOU NEED TO FIX SUCH IMPORTANT BUG. IT IS UNBELIEVABLE THAT IT IS STILL THERE SINCE 2009!!!
Hope this helps.

Both on CLI & through my Gnome file browser (Nautilus), I can't re-name, delete, or create new files. I don't understand what has changed. I then tested this on a spare laptop running Ubuntu 10.10 and it too has the same issue.

Apple Mobile Devices Support USB Driver issue

While I am aware this is a somewhat common problem, I have already followed all suggested routes I've seen for fixing it, and none have worked. My computer seems unable to detect my iPhone at all, and seems to fail to install the AMDS USB Driver (though all other elements of iTunes appear to install correctly.
Here is some relevant information to help troubleshooting.
I have already stopped and restarted AMDS and enabled automatic startup (http://support.apple.com/kb/ts1567)
I have already uninstalled and reinstalled iTunes and related services (Including AMDS) (http://support.apple.com/kb/HT1923)
I have tested all relevant hardware, including the iPhone itself, the connecting cable, and the USB ports that I've used, and all are functioning correctly (The iPhone can connect to other computers using the same cable, the computer can connect to other devices using the same USB ports)
I have the newest version of iTunes available (11.1.5)
While Apple Mobile Devices Support is installed, the USB Driver associated with it does not appear in the device manager. I have checked all folders in the device manager, including (but not limited to) Imaging Devices, Portable Devices, and Universal Serial Bus Controllers.
There are no "Unknown Device" entries in the Device Manager
My operating system is WIndows 7
Both before and after reinstalling iTunes completely, Windows is unable to detect the iPhone in any obvious way (My Computer screen, Device Manager, etc). The USB driver for Apple Mobile Device Support is not disabled, but rather does not appear at all.
What could be the cause of this problem? Is there a way to install the USB driver by itself without installing/reinstalling the related iTunes applications?
Any help on this issue would be greatly appreciated.

really? so apple.com arent checked by those who work on apple improvements? that would be kinda stupid im my ears. some comments here have an answer from ppl with an apple symbol, "specialists" they call them self. need some respons from them maybe.
i have tried everything, worked fine before the latest patch, so why cant it be a driver bug? they are humans too, they who make drivers. they just have to admit they had done something bad here, and solve it fast.
can i download an old itunes or something so i can atleast send my photos over.
the PC dont even say "couldn't install driver" or what it says in english, nothing happends at all. the drivers are there.

The "Unable to install Apple Mobile Device USB Driver" problem

Ever since I installed iTunes 10, I've had nothing but problems. I tried every fix I could find on the internet, unfortunately there are not too many, Apple's own website has loads of fixes but they never work.
I keep getting the Apple Mobile Device USB Driver come up in Device Manager with a little yellow exclamation mark and nothing I seem to do can fix it properly. I managed to fix it once, my iPod was synced and all was good, but once I restarted my PC, the problems started again. And I tried my friends iPhone which works perfectly and the same problem came up on my PC.
Cant someone give me a proper fix please?

I had the same problem with my iTouch when I upgraded to iTunes 10. I'm not sure if my problem was the same as with the nano but every time I reinstalled iTunes and plugged in my Touch, I got an error message for driver installation and the Apple Mobile Device USB Driver in Device Manager with a little yellow exclamation mark. The error message that came up stated something about the digital signature of the driver not being right. The fix that worked for me was as follows:
Delete the 2 Apple Mobile Device USB Driver files. If you right click on the Apple Mobile Device USB Driver in Device Manager and select properties it will tell you where they are located in the windows folder. My 2 files for windows 7 64 bit were:
usbaapl64.sys
usbaaplrc.dll
With ipod disconnected, restart computer and press F8 to enter boot menu.
Select boot option without digital driver signature support.
After boot, connect ipod and driver should automatically install correctly without error.
Good Luck
I called Apple and they would not provide any unpaid support for iTunes issues.

How can I use a existing USB Driver in NI VISA 3.0

Hello,
we have an ftdi USB driver for our measurement device.
The FTD2XX.sys is registred in C:\WINNT\system32\drivers
Also I have a FTD2XX.dll and an FTD2XX.inf file.
But I don´t know how can I register them in NI LabView or VISA.
Have I to do a new *.inf file for VISA?
Thank you
Cedric

You can either use the manufacturer-supplied driver or NI-VISA to control your USB device but not both. If you have installed your device, each time you plug it in the FTD2XX.inf will associate your device with FTD2XX.sys. Then, you can use FTD2XX.dll to talk to your device using the call library function node. The DLL usually contains a whole bunch of useful functions that someone else already designed to talk to your device. This is the easier route and I would recommend it if you already have the DLL and the installed driver.
The second method would be to uninstall or disable the driver for your device and create an .inf file with NI-VISA Driver development wiazard. This .inf file will tell Windows to use VISA as your device driver. You will, however need the vendor and product ID of the device to use VISA as your driver. The details of this are outlined in the NI document "Using VISA 3.0 to control your USB device."
The drawback of this method is that VISA is just an API to talk to your device and you have to implement the communication protocol to talk to your device. This might take some time to do.
This is why I recommend the first method. Someone else already implemented the driver for your and you just have to use the functions from the dll to implement your application.
Hope this helps.

USB Drive unmounts from airport extreme

I have a 1TB segate USB drive mounted on my Airport etreme which I mapped as drive z: on my win 8 laptop.
Somtimes when the laptop comes out of sleep mode, the drive will not remount unless I reboot the PC.
Somtimes I can't even remount the drive using the base station agent, it will not let me log into the drive.
Yes the drive is formatted as fat32.
Any suggestions?

You can use thumb drive.. it has to be formatted correctly.. fat32 or HFS+ of course.
And they are not very big.. so I am not sure how big your songs are.. in the apple world you have your songs on itunes and definitely this is unsuitable for the itunes library.. you still need itunes on a computer to share it to the network.

Installing Leopard on external USB drive

Hi there,
I am trying to wipe a drive clean via an external USB drive box. Might somebody explain how I can do this? When I boot on the Leopard DVD I arrive at the drive choice screen and there is a big red "exclamation point" on the external USB drive mount icon. What can I do to get around this problem?
Cheers,
Noah

Although you can boot some systems via USB, the drive must first and foremost be bootable. Not all external drives are bootable. The firmware must support booting. For example, my Maxtor 160 that I use for TM on my G5 states in the manual that it cannot boot.
You are having a somewhat different issue, in that you are not yet ready to boot, but the drive cannot be seen by DU.
I would see if the external drive can first be partitioned and formatted in Leopard directly by running DU in the Leopard Utility folder, not from the DVD.
I would check for a firmware update for your drive box.
