Access USB mass storage dev on Netra 20

HI all,
We just got a Netra20 server for our lab and noticed the USB support it provides. I plugged a 128 Mb USB JumpDrive but have been unable to access it. I found some docs in docs.sun.com related to the topic where it instructs to do an eject -n (to see the device-alias available) however all I see from the output is Floppy and CDROM aliases, no generic usb alias. Also tried killing and restarting "vold" but no use.
Does anyone know what is the proper procedure to access it? BTW I am running Solaris 8. Is USB supported in Solaris 5.8?

USB is supported in Solaris 8 / SunOS 5.8. This includes usb devices that implement the USB mass storage
specification.
You may want to install the latest USB Framework patch 109896-21, it fixes several issues with usb mass
storage devices, and even adds USB 2.0 support.
But: The "Lexar (?) JumpDrive" (and other Lexar Products) seems to be a problematic device. It seems
this product does not work too well (or work at all) with Solaris' USB drivers:

USB Mass Storage device problem

Hello, I cant use my USB mass storage device in my computer, it is a SanDisk ImageMate CF/SM unit, which works perfectly in every other computer I have tried it, but in this one it hangs while accessing the device, and in linux, it hangs while mounting it (the same thing).
I dont know what might the problem be but some other people have seen the same problem, perhaps someone here can help me.

Yeah, I though so, but first I wanted to know what might be causing this incompatibility, in the linux posts people have said that it is a nForce2 generic problem, perhaps a big nvidia bug? heh

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!

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.

Usb masse storage in solaris 10 problem !!

Hi all
i have srss 3.0 with solaris10-GA, all work well but the usb masse storage
does' nt recognize by srss3.0 are there solution for that problem.
or patch for srss 3.0.
thanks team

Congratulations on your choice of Os ;-)
To solve this problem you can try and create a directory called /rmdisk , then start vold running:
/etc/init.d/volmgt stop
/etc/init.d/volmgt start
if you are lucky your USB flash will show up under /rmdisk/<name> after a few seconds.
If not you should be able to see the flash with cfgadm, which list the status of USB ports (among other things).
Solaris should automatically create a /dev/dsk/ and /dev/rdsk/ entries for your flash memory, if its not automatically mounted by vold, try and stop vold using
/etc/init.d/volmgt stop
Then do a cd /dev/dsk and run an ls -lart, the USB devices should be among the last devices in that list, then mount it using:
mount -F pcfs /dev/dsk/<device> /some/directory
the device should end with s2 or p2, some flash devices might also need :c, aka /dev/dsk/<device>:c, it depends how its configured.
See man mount_pcfs for more information...
Hope this helps a bit (:

Can't enable USB Mass Storage

I am trying to use recovery software (Recuva) to replace deleted photos. When connecting to my laptop, I can only choose Media Device (MTP) or Camera (PTP). Recuva cannot find my phone without USB Mass Storage enabled but that option seems to no longer exist? What can I do to enable this?

You need to enable USB debugging on phone, so the computer can see it as a storage device.
Go into Settings, then scroll down to the bottom and click on About Phone.
Scroll down to the bottom to where it says “Build Number”.
Tap on “Build number” 7 times. After the third tap, Android will start counting down on how many taps are left before you can access the developer options, with a playful “You are now [insert number of remaining taps] steps away from being a developer”.
After the 7th tap, you’ll get a “You are now a developer!” message.
Now, go back to the main settings screen, and voila, the “Developer options” menu will be visible at the bottom, just above “About phone”!
Developer options->enable USB debugging

Samsung A900 USB mass storage and Tiger

I just got a Samsung A900 phone, when I connect with USB as mass storage device, the phone is mounted write protected in 10.4.3. In 10.3.9, it mounts as a writeable drive.

Hi there. I just bought a Samsung A900 and figured out how to use the phone as a USB Mass storage device:
My setup is a PowerBook G4 with 10.4.6 all updates (including the latest Security Updates and iLife '06 updates).
1. Plug the USB cable into the phone, and your computer.
2. The phone should say "USB Cable connected" on the main screen. If it doesn't, turn the phone off, and back on again with the cable plugged in.
3. Press the Menu button
4. Go to Tools
5. Go to Mass Storage
6. Select "Connect to PC."
You will not be able to receive phone calls while the phone is in USB Mass Storage mode.
A new volume should appear in the OS X Finder as "Untitled."
You have access to the same folders as with a Bluetooth connection.
Unfortunately, this also means that it is not a solution to get custom ring tones from an MP3 you own.
I tried looking in Terminal for any hidden folders, and I can't find any. I honestly think a firmware update/hack is needed to enable this on the phone.
Hope this helps.

USB Mass Storage function Z10

Hi guys.
I use my Z10 as a USB drive to play music from my car stereo & others.
To do thay i go to:
1. Configuration
2. Storage & Access
3. Media Card Details --> Turn on USB mass sotrage
However, I have to do this setting every time my phone reboot because my selections is just forgiveen by the configration settings. The problem is that too many days a week i drain my battery so the phone turn off and the USB mass storage functions is disable.
Is there any way to set this setting to ON just one time, and when the phone is restarted it dont go automatically to OFF state?
Thanks in advance!

Hey buddy.
I came across the same query when I first got my Z10. I tried every / any way possible to have it defaulted as "ON" though there isn't.
So for the meantime we will need to do this extra step every time our phones restart (until BB rolls out an update which does otherwise). I'm sure we're not the only ones who have run into this annoying un-user-friendly step.

USB Mass Storage Mode Missing :-(

I just upgraded? to the Samsung Galaxy S III today and have been very happy for the most part. However...
I am EXTREMELY disappointed that the only options to transfer files to the phone/SD Card are to use the MTP and Photo protocols. I always loved my Android phone...built off of open source software...and using open standards (things like USB Mass Storage). It is incredibly useful to be able to plug my phone into almost any PC, running any OS, and be able to transfer files to and fro.
Where is the rest of the uproar? When are we going to demand that one of the most useful features on our phone be put back. It was already there...it was already working...and has been dropped for lame, limited use protocols... Why? Who is getting paid off? Why?
Bring back USB Mass Storage Mode!!!!

It is always a good idea to do some research... I have followed your suggestion and found that Google has two reasons for using MTP instead of USB Mass Storage. They are:
1) “A main reason for using MTP rather than for example the USB mass-storage device class (MSC) is that the latter operates at the granularity of a mass storage device block (usually in practice, a FAT block), rather than at the logical file level. In other words, the USB mass storage class is designed to give a host computer undifferentiated access to bulk mass storage, such as compact flash, rather than to a file system, which might be safely shared with the target device (except for specific files which the host might be modifying/accessing). In practice, therefore, when a USB host computer has mounted an MSC partition, it assumes absolute control of the storage, which then may not be safely modified by the device without risk of data corruption until the host computer has severed the connection.“ -sombody from Google
--My Response - "I am totally OK with the SD card not being safe to be mounted. During the time I choose to be connected (only when transferring files)...I DO want the PC and not the phone to be in complete control of the SD card."
2) “MTP is a big improvement over USB mass storage — for devices with lots of internal memory, a manufacturer no longer needs to come up with some hard partition between the USB mass storage and internal storage. Instead, they are all in one partition, with MTP providing access to the directory of media files that would normally be available through USB mass storage. This means there is no longer a need for apps on SD card for such devices, because what used to be the ‘internal SD card’ is in the same partition as where applications are stored. The storage on your device can be used for either applications or media, depending on what you want to put on it. You aren’t stuck with how much space the manufacturer decided to leave for the two areas." -somebody else from Google
--My Response - "I am completely OK with the removable SD card being treated separately. That is EXACTLY what I want. I want to keep MY DATA separate and only on the removable SD card. And all of the stuff that I don't care about...that can be easily reinstalled (apps and such) on the internal memory. It is a good design. The phone has enough internal memory that I don't have any trouble with space for Apps (so not a conern at all)."
--My Overall Response - "The loss of flexibility, portability, and usefullness does NOT come close to justifying removal of the USB Mass Storage protocol. I am still VERY disappointed."
Where is the THUMBS DOWN... and INCORRECT ANSWER?

Without providing access of mass storage,allow access of data card or local printer ,

Hello,
Pls assist in exploring the possibility to allow access of data card or local printer without providing access of mass storage.
Balwan Singh

Hello Balwan Singh,
You can use two methods on is using Administrative Template and the other is using Preferences, both are available within the GPO in Domain Controllers with 2008 and later.
Option 1: Administrative Template.
This setting can be configured either at Computer or User level.
You need to go to:
Computer or User Configuration\Policies\Administrative Templates\System\Removable Storage Access
In here you can Enable the setting "Removable Disks: Deny read access" or "Removable Disks: Deny write access"
Just be aware that this settings does not apply to a servers at a "User Configuration" level.
Option 2: Preferences.
This setting can be configured either at Computer or User level.
You need to go to:
Computer or User Configuration\Preferences\Control Panel\Devices
In here you need to create a new item as follows:
- Right click and select new --> Device
- On General Tab you can select two "Action" options "Use this device (enable)" or "Do not use this device (disable)" in this case you should use the second option "Do
not use this device (disable)"
- On "Device class:" you can browse the devices attached to the computer from where you are configuring this GPO.
In this list yo need to choose the "Universal Serial Bus controllers" node and among the options listed in here you should choose the "USB Mass Storage Device" which is the class used for USB drives.
Remember that if you are configuring the GPO from a domain controller probably you do not see the "USB Mass Storage Device" in the "Universal
Serial Bus controllers" node since there does not exists a USB drive directly attached to your domain controller.
You can workaround this by either connect a USB drive to your Domain Controller or connect with the Group Policy Management Console (GPMC.msc) from a workstation on which you can safely plug a USB drive just to be able to visualize it and configure your GPO.

Canon Vixia HF R400 - USB Mass Storage?

I recently purchased a Canon Vixia HF R400 and was wondering if there is a way to make the camera appear as a USB mass storage device (like an external hard drive or flash drive).
When I plugged in the camera using the provided USB cable to a Debian (Squeeze) system, Shotwell Photo Manager appears as an option but it never successfully gets any data.
I've looked through the manual but found no reference to USB mass storage. Am I limited to Windows/Mac for accessing the files via USB? That would sad, as I have neither available to me at home.
Thanks in advance!

FYIGMO63: I'm using Linux -- Debian (Squeeze). I don't own a Windows nor a Mac system.
I've seen mention of other models of camcorders where the user is apparently asked to select their USB mode, but my camcorder doesn't seem to prompt for that. I poked around the settings menus as well and didn't find any where to specify USB connection mode.
Just so that I'm looking in the right place, could you give me an example for how you would do that on your camcorder (and what model you have)?
It would REALLY be nice if a CANON representative could look at this thread and tell me what I might be doing wrong to mount the camcorder as a USB Mass Storage device ... or if it's even possible under Linux.
I have 6 days left to return it at BestBuy, which I'd like to do if I can confirm that this is not possible for me, as I mentioned above, I have no Windows nor Mac computers here so I would need a generic USB Mass Storage solution that works in Linux.
Thanks!

Usb mass storage [FXx]

I know this has been discussed before, but I'm still confused basically with devfs which I find a bit mysterious...
I have a camera and a mp3 player I used to just stick into my slackware box and then mount it on either sda1 or sdb1 - I had the relevant modules loaded already. But I'm finding this difficult with AL...
I recompiled the 2.6.1 kernel with scsi support and usb stuff built as modules. On boot up, I load scsi-mod, sd-mod, usb-storage and usb-uhci from rc.conf. As far as I know, this is all you need to handle mass storage devices.
So, basically I'd really appreciate if someone could provide a real basic guide to where these devices get mounted under AL - I never added anything to fstab before, so I guess I don't need to now...
If I try to mount anything I get the contents of /proc/bus/usb, and the devices file there is not picking up my mass storage devices.
Any help gratefully received.

thanks for your input dp...sorry I didn't reply sooner.
This is the current situation - I now have loaded the usb modules and the scsi modules you recommended - (sg, sd-mod, sr-mod, scsi-mod). It takes a while but eventually I get some action in /dev.
I now have a /dev/discs/disc1 which I didn't before. This containe disc, generic and part1. I tried to mount part1 with mount -t usbfs but when I checked the mountpoint, it just contained the contents of /proc/bus/usb (a devices file, and 001 & 002).
I also now have a /dev/scsi/host0/bus0/target0/lun0 which contains disc, generic and part1 as well. I get the same results if I try to mount this part1. I never had a problem with usb beofre, so please excuse my ignorance! The documentation at linuxusb.org is not too great (well, for my needs at least).
Dmesg is saying:
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 0
usb-storage: queuecommand called

usb-storage: Bad target number (1:0)
usb-storage: scsi cmd done, result=0x40000
usb-storage: *** thread sleeping.
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 5
Well, it's just a sample;)
I'd really appreciate some tips on where to go from here - am I mounting the right thing, doing it the wrong way??
Thanks in advance.

Disabling of USB Mass Storage affects Default Printer setup

When I try to disable USB Mass Storage using HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor equals
4, the default local Printer i.e. HP LaserJet Pro 400 - M401D stopped working.
To avoid this thing, I have to once again enable the USB feature using
3 and re-install the printer driver along with all its application.
It never happened when tried in Windows XP Professional earlier.
Can you please provide solution of this?

Hi,
In Windows 7, you can disable USB by following GPO:
Computer Configuration > Administrative Templates > System > Removable Storage Access
Removable Disks: Deny execute access Enabled
Removable Disks: Deny read access Enabled
Removable Disks: Deny write access Enabled

USB Mass Storage Device - ?

Shuffle shows up as a USB Mass Storage Device under the drive (USB Port) i plug it into.
It will not take an update or reformat.
Wondering if it is possible that the factory format could be erased and now the unit is just being recognized as a storage device and unable to be used in the manner it was originally intended for...MUSIC.?
What does it mean when you get a message "Media in Drive - Changed" ?
Fixed many other ipods in past but only one shuffle so far....now this one has me going...no clue what else i can do to it.
Any help would be appreciated.

i think it was trying to read the shuffle when i wanted to format and restore.
i never did get it to work.
no way of knowing now..i just got through tearing into this one to make one good shuffle out of the two i was working on.
all was good till i went to put the slide bar on/off switch back on....broke the switch again.
do you have a switch?
thanks

Windows 7 64-bit not loading USB mass storage driver

I have a rather strange problem with my Windows 7 Ultimate 64-bit. Everything seems to work fine except for USB mass storage devices. I have USB keyboard, mouse and even a USB audio (wireless headset) all working fine on the computer. But
any USB external drive, thumdrive or USB card reader with flash cards inserted into the USB port of my computer won't work.
Windows keeps reporting that it is unable to find the driver. When I go into the Device Manager console and choose to manually update the driver, then point it to the C:\Windows (with search for sub-directories enabled), it detects the USB Mass Storage
driver but complains that it is unable to load it. The exact message is this: Windows found driver software for your device but encountered error while attempting to install it. USB Mass Storage Device. The system cannot find the file
specified.
This happens to ALL USB Mass storage device, and it doesn't matter which port I plug the device into.
Here's the weird thing, I have VMware Workstation installed on this computer and if I power on a VM that runs Windows 7 32-bit as the Guest OS and connect the USB storage devices to the guest OS via VMware Workstation, the USB storage devices work!
So it would appear that the USB ports are functioning properly but for some reasons, my Windows 64-bit is unable to load the driver.
Any idea how to fix this besides a "nuke it from orbit" and format/reinstall Windows?
Thanks.

I'm very excited to finally have a solution for this problem. Thank You Balaji for figuring this out. I've been struggling with this for a number of years, and had only one USB Hard Drive that worked. I too have VMware workstation, and had the missing files
in "c:\windows\inf." I can say with certainty that I did not delete the files from that folder, but something is common in both of our situations. Maybe it has to do with VMware, and some of it's updates over the years. I'm also using nCompute to share out
a networked desktop via the wire.
One more thing worthy of mention is this machine was an update from Windows Vista, and the USB hard drive that worked was configured back than. So although I could never add another HD, at least I had the one.
Now with having copied over the files, I can plugin other USB enclosures with different drives and they too are working.
Like you mentioned, it was always possible to use USB devices within my Virtual Machines, so it was clear that the USB ports were functional. I actually got the files from a clean Windows 7 VM, copying out the \windows\inf folder and doing a compare between
the the real one and the virtual one. I found the two missing files you mentioned, along with 8 others. I went ahead and included them all in your fix.
It worked, Amazing. Thanks again. :O)
