Cypress - Other hardware - Cypress At2 USB Storage Adapter

Question

I have a USB Disk Enclosure that was working with Windows 8.1.  I recently installed a Windows Update optional update titled "Cypress -
Other hardware - Cypress
At2 USB Storage Adapter" and the next time I attempted to use the disk enclosure, it did not work.  When I connect the device the system makes a sound like it recognizes a device and the
Device Manager display gets redrawn (refreshes), but no device shows up in Device Manager, Disk Manager or Safely Remove
Hardware and Eject Media.  I have booted, also without helping the situation.  I am thinking that I should remove the update, but the "Uninstall and update" panel does not list and update title that matches the above.
Update #1:  I found the same issue from two others on another MS forum that was posted yesterday: answers.microsoft.com/en-us/windows/forum/windows_7-windows_update/crypress-a2b-usb-driver-update/96765e04-7f4a-42fb-bf37-ca98fa8fc0cc?rtAction=1395927639282
I have had MS Support remoted into my system all morning and am being told they want $99 to run their tools to fix the problem.
Update #2:  After hours chatting w/MS Support, no progress.  They ran lots of virus scans and repair procedures.  I did make the following observation.  When the USB Drive is connected, the system recognized something and chimes as described
above.  What actually changes is that a "Cypress AT2 USB Storage Adapter" devices appears in the "Universal Serial Bus controllers" tree of Device Manager.  When the drive is unplugged, this device disappears.  Before the
Win Update that I suspect caused the problem, the drive would appear as a drive also.  Note that the original behavior had the device appear as a disk, not as a removable device like a flash drive.  So Windows is recognizing the storage controller,
but not presenting the attached disk as a drive in windows.  Oh well, back to the MS Support Chat......
Update #3: I contacted MS Support a second time and pointed them at the “Cypress AT2 USB Storage Adapter”
that appeared when the USB Enclosure was plugged in.  They poked around for a while and finally “Uninstalled” the device driver and had me unplg/plug the drive and BANG, the drive appeared. 
I don’t know if it was the 5+ hours of work the first support person did or if that was the solution all along, but the drive works now. 
Oh and one more thing, as I was completing the survey for the support, with not good ratings I might say, the remote control connected support person booted my computer right out from under me without a word of warning. 
I guess there is more than one way to keep survey ratings high.

Answer 1

Same problem. To solve you have to uninstall "Cypress At2 USB Storage Adapter"
removing driver files with the option suggested by the dialog box of device manager. (I'm sorry i can't use the correct words because I own the italian version)
After that, when you connect the drive, il will correctly mount the volume and do not appear Cypress device anymore.
