genuine is sticking on my cupter
2009-02-26 windows update suggested following drivers
Cypress - Other hardware - Cypress AT2LP (3.03.0000.2)
Cypress - Other hardware - HX2LP Kit (3.03.0000.2)
Now my yakumo 250 GB USB external harddrive is not working.
Its not to be found in system. I can not uninstall these
cypress in device manager or add remove programs.
No drive letter appears when using Cypress manufacturing drivers
Last Updated: 12/19/2008
The Cypress manufacturing drivers are used to interface with the AT2LP for such operations as programming the EEPROM or running factory tests. No mass storage interface is enabled when using the manufacturing drivers, so no drive letter will appear. This is normal expected behavior.
Note: Cypress also offers mass storage drivers, so confusion between the manufacturing and mass storage drivers sometimes occurs.

"" Is it the wrong driver on windows update?
My disk cleanup will not open. How can I fix
I used my system restore using a system checkpoint from this AM and it removed Cypress AT2LP (3.03.0000.2). In my update history it still shows, but when you run Windows Update it shows that you can install it again. I then marked it hidden.
My USB hard drive came back immediately upon removing this supposed upgrade. Dave
How can I repair this situation if I dont have a restore point? Any clues?
Yes, if you don't have any restore points, simply open Device Management (devmgmt.msc) and find the HX2LP Kit (or Cypress) entry under the USB controllers section and click "Rollback" on the driver, and then reboot. Should also fix the problem!
PS: What a nasty side issue this is :(
Ook - that worked perfectly. Thank you so much. If we were at a bar the beers would be on me.

I have the same problem of not being able to see my USB hard drive. It's mounted within my docking station for my laptop. The USB ports on the docking station also do not work. I understand the fix outlined above, but when I'm in device manager, there is no HX2LP or Cypress listed. I think XP may have shutdown or hid this whole driver? one time when the battery ran out of power while it was undocked.
Any ideas on how I can fix my similar problem?
Any help would be greatly appreciated.
Hi, before I read this solution, I deleted the driver and installed again but nothing. now I can't rolback! the roolback button aint active.
i have fixed this by hand so many times, but it's great to have an auto fix! Thanks!!
ever since auto updates, I cannot open e-mails containing videos. WHY?
my laptop mem slot, Webcam/touch screen are totally dead after cypess updates. but my "roll back" button is disabled although my account is admin type. anybody can help? thanks in advance.
If I'd been able to find this method/fix-it tool for Disk Cleanup not compressing old files, it could have saved me one reason for an O.S. uninstall/reinstallation.
