What is a USB mass storage?

First make sure you have the correct USB drivers for your phone installed on your pc. Go to device manager and see if your phone or mass storage device is listed. If not, download the drivers here, http://www.samsung.com/us/support/downloads. Make sure debugging on your phone is enabled. Please refer to the following:

1. To set the Samsung Galaxy S2 to USB Mass Storage (MSC) mode, go into "Settings > Applications > Development" and enable "USB debugging".



2. Then drag the status bar down and tap on "USB connected".



3. The "USB connected" screen with the large green Android icon will appear. Tap on "Connect USB storage".

A confirmation dialog box will appear. Tap "OK". The green Android icon will turn orange, indicating that the phone is now in USB Mass Storage mode and should now appear as USB disk drives in "Devices with Removable Storage" and be assigned drive letters.

right click my computer, device manager,you should now see a list roll down list till you see universal serial bus controller,click on this and a list will drop down, the first 1 you see in list right click and pick update driver software.keep going down list doing the update software driver .that should reinstall missing usb storage driver .try pluging in an external hard drive if it reads drive and you can put and remove things then its already install but not showing.

The hubs were most likely the USB hardware that is a part of your computer, but the USB Mass Storage Device is a part of some hardware that you had plugged in at some point (maybe a USB flash drive, maybe a USB external drive). In order to reinstall the Mass Storage Device, you have to plug that hardware back in and let it reinstall. If you aren't aware already, sometimes you plug in one device, but it installs as more than one device (it's actually supposed to). So you won't always have a one-to-one ration of hardware and installed devices, since some of them show up as more than one device. And typically, when plug a new device in for the first time, the computer can only see one device, then it instals that one device, and only then can it see the other (virtual) devices, which it then installs. The next time you plug that device in, it sees & activates all of the devices instantly & silently (not counting the little "plug in" sound it makes).

Hello.

You need to install to your computer the software that came with your phone. If you don't have it, you can download it here:

Samsung Software

Once you open the link above, click "Software" beside Manual.

use a usb cable to hook to computer

Since there's no easy option in the Walkman's settings to switch back and forth between MTP and UMS, there's a little trick to un-do the MTP drivers so that the unit becomes a straight USB Mass Storage drag/drop unit. You have to go into Device Manager (Windows XP), find the Walkman in the Portable Devices group, right click, then select Update Driver. Then select "No, not this time", then Next. Select "Install from a list or specific location (Advanced) then Next. Select "Don't Search, I will choose the driver to install", then Next. (Be sure to check the box beside Show Compatible Hardware) Highlight USB Mass Storage Device, then Next. (To revert back to MTP, just do the same thing but choose MTP instead of USB Mass Storage Device.) Personally, I'd never go back to the MTP mode. Having the Walkman seen by the computer as just another USB mass storage device allows the drag/drop transfers to go much faster

The mass storage controller is generally for usb devices that you've plugged in. USB keys, memory cards etc.

This kinda falls under the realm of the USB drivers for your mainboard... which if they're working, you don't need to do anything. XP service pack 2 supports USB2 just fine, but service pack 1 will require you to get your manufacturers drivers to get USB2 working at full-speed.

Why do you want to change the default driver anyway??

you actually don;t really need the CD. you only need the cable to connect to a pc via USB. or you can connect using Bluetooth if your computer supports bluetooth

if your connecting via USB. be sure to set some settings first

go to <Phone Settings
>Connectivity
> USB Connection
> select MASS STORAGE

when you plug your phone. your phone should act like a regular mass storage device. Take note that only the External Memory is accessbile. (NOT the INTERNAL Phone Memory) so be sure to have a Memory card in your phone.


so it will be helpfull to set the default storage of pictures/files/etc to the external memory

Hmmm..

Make sure your using a USB cable, specifically a USB cable with a mini connector on the end. Specifically, a USB cable with the second one from the left in this picture:

If you are using the USB port, you should have no need for setting COM ports.

Another technique you can use (which I just figured out today) was to place the Garmin Unit in "USB Mass Storage Mode". This allows you to offload saved tracks, but I don't think you can download waypoints or other things that the WayPoint Manager allows.

You can access this option via the Garmin Unit

Goto: "Main Menu" -> "Setup" -> "Interface". Press Down to get to the button "USB Mass Storage". Plug in that USB Mini cord, and you have a thumb drive!

Good Luck!
