I lost the log by doing ".. scanimage -L 2>&1 | tee file"; scanimage
doesn't produce it if stderr goes into a pipe.

This looks like the relevant part:

 [sanei_usb] sanei_usb_find_devices: vendor=0x04b8, product=0x080d
 [sanei_usb] sanei_usb_open: trying to open device `libusb:002:003'
 USB error: could not set config 1: Device or resource busy
 [sanei_usb] sanei_usb_open: libusb complained: could not set config 1: Device or resource busy
 [sanei_usb] Maybe the kernel scanner driver claims the scanner's interface?

Since the only change was a new kernel, here are the "USB" changes
to the kernel configuration:

	> CONFIG_USB_PRINTER=y
	< CONFIG_USB_STORAGE=m
	> CONFIG_USB_STORAGE=y
	< CONFIG_USB_PEGASUS=m
	> CONFIG_USB_MON=y
	< CONFIG_USB_SERIAL=m
	< CONFIG_USB_SERIAL_KEYSPAN=m
	< CONFIG_USB_SERIAL_KEYSPAN_USA28XB=y
	< CONFIG_USB_EZUSB=y

And, for completeness, the entire log file:
