Good (or bad) that means that the problem is on your laptop.

It can be of TWO types:

• hardware
  
• software
  

If hardware it is possible that the USB controller of the laptop is gone beserk.

If software it can be:

• a problem in the Registry for the specific stick
  
• a problem in the Registry for the USB bus
  

In all cases next test is using another USB Mass Storage device on the laptop and see if the other USB stick (or hard disk) is detected properly.

If yes, it's not a hardware problem and not a "generic USB bus" software problem, which shuld leave with just one possibility:

• a problem in the Registry for the specific stick
  

See if the info here helps:

the thread you mention is so extensive and more or less irrelevant, can you give me a solution to the "usb device not recognized" of a usb stick problem?

how to fix the registry problem of the specific stick?

I have NO solutions up my sleeve.

You completely fail to report the result of the tests I suggested you.

How do you expect I can help you? .Unsure:

nope, I reported succesfully!

there is no hardware problem with neither pc nor the usb stick

so I am looking for the software problem solutions, which I am pretty sure so many people have needed and used them, that's why I am asking straight forward

OK.

BACKUP your current Registry with ERUNT:

http://www.larshederer.homepage.t-online.de/erunt/

MAKE SURE you understand (and have a way to) how you can restore the Registry should it fail after the edits.

Disconnect ALL USB Mass Storage devices you may have.

Open Regedit.

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB

Check one by one each entry in the form Vid_xxxx&Pid_yyyy, if it does not corrispond to anything USB connected that you know for sure you are currently using, delete the key.

Take note of all the Vid's and Pid's you delete.

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR

Check one by one each entry in the forms:

• CdRom&Ven_xxxxxxx.......
  
• Disk&Ven_xxxxxxx.......
  

if it does not corrispond to anything USB connected that you know for sure you are currently using, delete the key.

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}

Check one by one each entry, if the DriverDesc corresponds to "USB Mass Storage Device" or "Unknown Device", delete the key.

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{53f56307-b6bf-11d0-94f2-00a0c91efb8b}

Delete any key with names in the form ##?#USBSTOR#xxxx......

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{53f56308-b6bf-11d0-94f2-00a0c91efb8b}

Delete any key with names in the form ##?#USBSTOR#xxxx......

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{a5dcbf10-6530-11d2-901f-00c04fb951ed}

Check the Vid's and Pid's against the list you made in first step, delete any key matching the ones you have deleted.

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags

Delete every key you can find in the form xxxxxxxxxxxx (12 characters)

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\Current\System\CurrentControlSet\Enum\USBSTOR

Delete any key that is in the form:

• CdRom&Ven_xxxxxxx.......
  
• Disk&Ven_xxxxxxx.......
  

Try re-booting.

If new hardware wizard pops up re-install needed drivers.

Check in device manager that you do not have items with question marks.

Re-boot.

Try again the stick.

wow this is so complicated

isn't there a tool or a fix? (software)

YUP Reinstall windows...

Yes, life is tough.

One-size-fits-all, automated solutions are out of stock, sorry.

We have only the above manual possible solution left, you may want to wait until the one-size-fits-all, automated solutions are created, but there is no deadline for them, I guess that they could be here in a couple of years.

Otherwise, if you have a problem, you may want to stop whining and try doing something about it, you may even learn something in the process.

isn't there a tool or a fix? (software)

There is an easier (hardware) solution :

Alternatively, re-partition your hard disk using the method illustrated in Figure 4.4:

You won't be hassled anymore by the "USB is not recognized" popup, the method removes ANY popup.

Just for the record, I have seen the concept of:

Thanks for the time you spent trying and helping me.

more explicitly worded.
