It seems to me that both are HP products. Therefore, HP should know more
about your problem than just about anyone else.
If their printer and their PC will not work together, that's really bad.

There may be a problem with the USB port hardware or software, or perhaps
the printer is loading the USB port excessively.
Have you looked at the hp support web site for this printer? And any support
info that is PC model specific?
Does the printer work properly on another PC?
Did you check for new drivers?
From the amount of information on the website concerning problems with this
printer, there have been more than the usual problems with the printer
drivers and installation.
