Windows 7 - Computer not Reading Mass Storage Devices

Alright guys/gals, I'm stuck!

Here we go.... I have a Android Phone(evo4g) and I also have a 60n1 Card Reader neither of then will read cards!

Card Reader= I put any card into it slot (sd,mirosd,sdhc,microsdhc) and it WILL show in computer as a "removable device" but if I go to open them I get "Please insert disk into Removable Disk (f" or whatever drive letter for the others.

Android Phone= Same as above but going through a usb cord.

(See pics...1&2... 1 card not inserted and 2 card inserted)



Also I noticed that in my Device Manager the drop down that should be "Universal Serial Bus Controllers" is shown as "Unknown". (See pic 3)


I have uninstalled and re-installed all of the above devices and their driver (including the Mass Storage Device drivers)
I have also run "sfc /scannow" 3+ times .. all with no errors.

Now I do know that the issue is with this Computer only, because I have tested all above Devices on my laptop that is running the same OS as this one and they all work as they should!

So If you can help me out please throw your smarts my way!!!

Pre-Thanks

When did you install the card reader into your system? Are you sure that you have the card reader header plugged in the right way if a 4 pin or 5 pin plug? If the card reader is a usb internal connection; is it connected to the right usb port and is that port activated in the BIOS?

Card Reader is new installed over the weekend. I got it because I had this issue between my phone(in mass storage mode) and the computer, figured I'd just work around it but discoverd it is not only the phone its any mass storage device.(my usb flash drives still work fine)

Anyway the Reader is an internal one yes it is plugged in the right way and activated in bios. Further more the bios does see it fine as does windows(as seen in device manager)

NOTE: Just from personal experience, if the header is not plugged in with the right pin order it can still pick up the device but it won't be a functioning device. I had to go in and flip the header around and bingo I had a functioning card reader.

Is there any drivers for this card reader that needs to be installed? What make and model carder reader is it?

Ok guys/gals,

I been off dealing with other stuff for a few days, but I happy to say I have got both the Phone(mass storage) and Card Reader working!!

So here is what I did,
First I went into Bios and turned off ALL usb support, rebooted,(had to use a ps2 keyboard) and let system boot, shutdown, back into Bios turned on ALL usb support, rebooted, let system boot up, then I when into Disk Management and re-assigned all of the New Drives (phone(mass storage) & card reader) New Drive letters (they had letters the whole time but I switched them around) and after all that they are now working (have been of two days)

Thanks to everyone for helping out!!!
