mass storage not working for multiple devices

There are a few devices I'm trying to connect to my computer as mass storage:

iRiver h320 (mp3 player)
Samsung Captivate (Android phone)
Samsung S10 video camera

My system is running Windows 7 Ultimate.  
Motherboard is ASUS P6X58D Premium

When I connect these, they show up on the list of "Devices and Printers" but they do not show up anywhere in "Disk Management."  They're not being assigned a drive letter, and unless I can see them in Disk Management, I don't know how to give them one.

Sometimes I can get the Android to show up as a drive, but then it's only under a minute before it stops working.  All of these devices have connected fine in the past.

Today I was trying to install RockBox on my iRiver device, but I can't do it unless I can direct it to a drive letter.  

What can I do to get mass storage file access to these devices?  Thanks!

maybe a stupid question but did you try another usb port? Normally i would guess the power on the port is too low and suggest using an usb-hub with external power.

could be driver issue. check the manufacturer's support website to see if any drivers and/or software around. Plug them in and try windows update to see if it picks up any drivers.

I've tried different usb ports, but no difference.  

It seems odd that all these devices would have driver issues.  The iRiver hasn't had a driver update in ages, but it used to work on this computer.  I've tried a few different drivers for the Captivate, but none make any difference.  I haven't tried messing with the video camera drivers, but that's lowest priority because I can just pop out the SD card and put in our laptop's reader.

By the way, they all connect to our netbook (Windows 7 Ultimate also) for mass storage without any problem.

try going to device manager, uninstalling what is there (regarding your devices) if they exist then plug in your device again

or

go to admin tools, services - is portable device enumerator started?

if they do work on another computer it might still be the power on the usb-ports... so I (As normally) suggest that you try to get an USB hub with external power... do other usb devices work correctly on your ports?

I think it was the portable device enumerator.  It was set to "manual."  I changed it to automatic and started it, and so far the phone and mp3 are now connecting.  I'll try the video camera tonight, and if that works (and I expect it to), then I'll consider this a problem solved.

that looks to be it then. the portable device enumerator manages removal storage devices - this including mp3 players and digital cameras etc.
