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.

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

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!
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.

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)

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

IPOD seen as two drives(USB Mass Storage & and Dell USB )

My IPOD classic has not worked properly since I updated my OS to Windows XP. At first the IPOD was seen as two different USB controllers (Apple USB Driver, and a USB Mass Storage Device) I've gone through every troubleshooting article on the apple website. After downloading a hotfix, my computer recognizes the IPOD as an IPOD but it doesn't connect to itunes long enough for me to restore it. It automatically disconnects after being plugged into the computer. If anybody can help, please, please please let me know.
Thanks.

I just purchased an ipod classic 120GB and after downloading itunes to the computer I can no longer use my DVD/CD drive as the ipod is using that drive now, which is the E drive on my computer. I noticed that if I uninstall itunes I get to use my DVD/CD drive again. I do not know what next to try either. So my ipod is seen as a mass storage device, I need help too, can anyone help?

Arch instance living on USB mass storage device is very slow

I installed an instance of Arch on a USB stick. This is a full installation, not a ramdisk-based "installer" or anything. However, this little guy is very, very slow. Sometimes, I have to wait for almost a minute between writes while the UI locks up (XFCE4, in case you're curious).
I think a lot of the problem comes from iowait load and pending write requests. I've been considering experimenting with data=writeback, but I've never used this ext option before, and thought I'd ask you guys about it first. I hear that sudden power failure can lead to pretty severe data loss with writeback enabled. Anyone have any experience with this? Are there any other tweaks I can apply to increase performance that would be appropriate for a USB mass storage device? I have noatime enabled, but that only gives it an almost unnoticeable bump.

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:

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.

LG Spectrum - Issue w/ USB Mass Storage funcionality

I just got this phone a few days ago and I am trying to play the music that I have stored on my phones memory card through my car stereo by plugging it in the USB port in my car. When I try to do this, the screen on my phone just flashes back and forth from the charging home screen to the regular home screen and it (my car stereo) says reading error. Prior to getting the LG SPectrum I had an HTC Evo on Sprint and it used to work whenever I plugged my phone into my cars USB port. Is there a setting I need to change in my phone or is this phone just not compatible w/ car stereos? This may be a question that I need to ask my car manufacturer but I figured I would start here for some advice.
On another note, I am also wondering if this phone has an indicator light. I have been looking ever since I got this phone but can't seem to find it anywhere. All I see on it is the front camera and a motion sensor. Am I missing something?

Yes I have tried that but it still gives me the same result. Itis a little disappointing that I can't get it to work like my Evo did. I never had the need for an iPod b/c my phone always did what I needed as far as music goes. So is am is it safe to assume that it won't be possible to play my music on my phone through my car stereo? Any way it could work through bluetooth? I am somewhat disappointed w/ some of the other features of this phone (especially not having a notification light) but I could get past that but not having the ability to have the USB mass storage capability is a huge let down.
