The SANe internal USB code tries to use the kernel scanner module, if
it's available. Otherwise libusb is used. The "usb vendor product"
lines in the configuration files are used for both libusb and the
kernel scanner driver. "scanimage -L" shows which type of access is
device gt68xx:libusb:001:004' is a Plustek OpticPro 1248U flatbed scanner
device gt68xx:/dev/usb/scanner1' is a Plustek OpticPro 1248U flatbed scanner
That's the kernel scanner module.

Try without APIC. Isn't it only needed on multi-processor boards?
