currently the XPA scans on 63xx do not work. I am working on this.

Try to check how the scanner device is opened by the hp-backend. Do that
by

export SANE_DEBUG_HP=5

and run xscanimage. You will see debug printouts. You should see
something like that:

...
[hp] hp_read_config: hp backend v0.XX starts reading config file
[hp] hp_read_config: processing line <scsi HP>
[hp] hp_read_config: processing line </dev/scanner>
[hp] hp_read_config: attach scsi HP
[hp] hp_read_config: processing line </dev/usbscanner0>
[hp] hp_read_config: attach /dev/scanner
[hp] hp_get_dev: New device /dev/scanner, connect-scsi, scsi-request=1
[hp] sanei_hp_device_new: /dev/scanner
[hp] scsi_new: open failed (Invalid argument)
[hp] /dev/scanner: Can't open scsi device
[hp] hp_read_config: processing line <option connect-device>
[hp] hp_read_config: attach /dev/usbscanner0
[hp] hp_get_dev: New device /dev/usbscanner0, connect-device,
scsi-request=0
[hp] sanei_hp_device_new: /dev/usbscanner0 
...

It is important that the line

[hp] hp_get_dev: New device /dev/usbscanner0, connect-device,
scsi-request=0

shows connect-device instead of connect-scsi.

This is a result of a hp.conf with the lines

scsi HP
/dev/scanner
/dev/usbscanner0
  option connect-device

If this does not help please post the debug lines from 

[hp] hp_read_config: hp backend v0.XX starts reading config file 

up to the first error message.
