Latest piece of information, in case it helps solve the puzzle: sane cannot 
open the HP all-in-one as a scanner 
with same error (getting serial id). However, my Nikon LS40-ED (a 35mm film 
scanner) works fine. So the problem is apparently not my installation or 
libusb.

found USB scanner (vendor=0x04b0 [Nikon], product=0x4000 [LS-40 ED]) at 
libusb:/dev/usb2:/dev/ugen1
found USB scanner (vendor=0x03f0 [HP], product=0x5c11 [Photosmart C4200 
series]) at libusb:/dev/usb3:/dev/ugen0

The Nikon scanner works, the HP device fails to return serial id as above. So 
it seems the Photosmart really fails to return a serial id.

This does not seem to be an outright violation of USB standard, does it? At 
least once upon a time vendors were allowed not to provide id's. Then either 
(a) hplip should catch the failure and deal with it. Or, (b) hplip being 
HP-specific knows that HP always has a serial id; then the printer must be 
really busted.
