USB device no longer recognized

I have a SanDisk 16gb cruzer that is easily recognized in my XP Pro
machines and was for a brief while on my 2 Vista Ultimate machines.
A few weeks ago, my 2 Vista Machines stop recognizing it. If I go to
device manager, I can see it listed as a disk drive. To get it to work
I scroll down to USB Mass Storage Device and disable/enable it and it
pops up and all is good. If I look in Computer Mgmt /Disk Mgmt, it
shows up as unallocated so it does not get assigned a driver letter.
If I boot the PC with the usb drive inserted it works fine. I called
Sandisk technial support and they said it was "Vista problem" because
the drive works in XP and in a friend's computer also running Vista.
Can one delete all USB devices in Vista without doing a complete
reload of Vista. Maybe setting all USB paramters back to that after a
clean install would help ?
Any help would be much appreciated. Steve

Instead of disable/enable try uninstall, and put it in another port if you
have one. I have a 256 Meg noname that does the same thing now and then.

Thanks for the suggestions...I tried both these suggestions and many
more and still no luck. One suggested deleting th eUSB and USBSTORE
keys in the registry. I changed permissions so I could do that and I
still cannot delete those keys. I put mys sandisk 16gb stick in
another pc runnig vista and it recognized it. I tried a frien'ds 32gb
stick in my 2 pc's... no luck on either pc. Very baffling! I hate
have to reload windows on my 2 machines that otherwise work just
fine. Any other suggestions?

I figured out what the problem was. I installed Acronis True Image
Home 2009 on both of my Vista machines about a month ago. That was
about the time my memory sticks stopped being recognized on these
machines. Once I uninstalled it and installed a new build of this
software, everything was working fine.

Once I uninstalled it and installed a new build of this
software, everything was working fine.

Curious as to where you got a "new" build?

I would assume from Acronis's web site. I am now on my 3rd build of True
Image 2009, all downloaded from they web site.

Camper

Are you downloading trial versions?

The reason I'm so interested is because I bought True Image 2009 via
disc and the gui has no option for updates.
On their website I see no updates for 9.0; plenty for 10.0 & 9.1 but
they are for servers and such.

Have you registered your product and logged on to their site? I just log on
to http://www.acronis.com.au and the site tells me what the latest update
is. Currently it is build 9770 released 29/8/2009 for true Image 2009.
Obviously unless you are in Australia you would not want to register and log
in to the au site.
