[b]Step 3: Removing all entries under HKEY_LOCAL_MACHINE/Enum/USB that start with VID[/b]

==================================================================

Removing the VID entries from the registry will cause them to be redetected at restart.

CAUTION: If you have a USB keyboard or mouse, do not remove the VID entry for these devices, otherwise, Windows may not restart correctly.

1. Click Start and click Run. Type regedit and click OK. The Registry Editor window will open. 

2. Go to HKEY_LOCAL_MACHINESystemCurrentControlSetEnumUSB. 

3. Highlight and delete all the VID_.... entries.

Permissions may be set allowing the deletion of the VID_ entries by following the steps below: 

a)      Right-click the key to be deleted, and then click Permissions. The VID_... Permissions window will open. 
b)      With Everyone highlighted in the Group or User name section, select Full Control in the Permissions section. 
c)      Click Apply, and then click OK. 

4. Turn off the computer.

[b]Step 4: Reconnect the digital camera to the computer system:[/b]

=============================

1.      With the computer system turned off, reconnect the Sony DSC-P50 camera to the USB port. 
2.      Restart the computer. 
3.      After the Windows operating system has finished restarting, plug the digital camera into the electrical outlet. 
4.      A New Hardware Detected window should open and reload the drivers.

If the camera still cannot work, I recommend you plug the camera to another Windows XP computer (Desktop) to test whether this camera works. I suspect it is an incompatibility issue. 

Thank you for your time. I look forward to your reply.

Soluzione: ho installato tutte le periferiche USB sul portatile con XP, e da file di registro ho esportato tutte le chiavi enum USB e USBSTOR e le ho reimportate sul fisso.

I DEV_ID ovviamente coincidono, riavviato il pc e finalmente le periferiche sono installate.

Sto cancellando tutti i VID_ dal registro adesso negli enum dell'usb, vediamo che accade al prossimo riavvio.

EDIT: Ovviamente cicche, mi ha solo cancellato tutte gli hidden devices dal device manager e rilevato le vecchie periferiche usb, quelle nuove non le vede lo stesso.

Mistero.

La cosa strana è che le vecchie periferiche usb già installate su questo pc continuano a funzionare come se avessero già i drivers installati, webcam, mouse, joypad, stampante, fotocamera e due pennini, ma qualsiasi nuova periferica che provo ad attaccare non funziona, sia usb1 che usb2.

Ll'os è xp professional genuino con ultimo sp3 e aggiornamenti, non ho virus, non ho spyware e altre amenità, le ho provate davvero tutte, nel registro, negli amministrative tools, ho aggiornato i drivers intel del chipset, ho cambiato tutti i settaggi possibili nella bios, provando a prendere le dll dal potratile che mi riconosce la periferica e copiarli in sysyem32 qui sul fisso, ma niente di niente, ho cercato su internet ma nessuno pare avere questo tipo di problema, voi avete mai visto una cosa del genere? avete idee sul come poterlo risolvere senza formattare?
