Question : Problem: HP Solution Centre No HP devices have been detected

Toshiba Satellite  A55, WIndows XP,  

I installed a different HP printer from the one I had (that worked normally with Solution Centre software)

The  new one is a Photosmart All-in-One 2575

Printer function works normally (eg. from Word, Excel, Adobe photo programmes).

Scanner initially also worked normally  but at some point it became impossible to use the HP Solution Centre software.  Error message claims "No HP devices have been detected" .  Apparently Solution Centre fails to recognise the driver files??   I have tried to remove all HP software from the computer then re-installing but to no avail.   I understand from the forums that this is a problem well known to all except HP.   I have had no success following the many and varied suggestions in the forums.  Have you a solution for this truly incredible problem?

How did you remove the software? Did you run the bat files that are normally in the CCC directory of the installation CD. When you installed the software again, did you use the newest download?

If that doesn't help, I'd try an online chat with HP. I've always found them pretty helpful.
