Problem with HP Pavilion PC and Acronis True Image

Hi,
I have a big problem. I have a HP Pavilion T3510.it PC and True image
Home. My backups are stored in an external IDE USB drive.
All work correctly, but when I boot from Acronis Media Disk,
come the problem:

All work very very very slowly and after I select what to start (Acronis True Image FULL) and come the Acronis logo on top left, appears:

usb.c: canno't retrieve device descriptor (error=-32)

However the true image start. But every times I click "Next" button,
the PC employ about 3 minutes for go to the next window.
When the program start the recovery process it say to me:

19 hours left!!!!
and the hard disk led flash every 30 secs and not always!

The backup is only 2 gb.

I have tryed to start the acronis boot cd kernel with "acpi=off" parameter,
but the problem persist.

With Acronis BartPE Plugin all work but I would want to boot from the
original acronis cd.

Anyone can help me?

Sincere thanks to who will succeed to help me.
