When doing an strace on scanimage -L:

open("./genesys.conf", O_RDONLY)        = -1 ENOENT (No such file or
directory)^M
open("/usr/local/etc/sane.d/genesys.conf", O_RDONLY) = 3^M
fstat64(3, {st_mode=S_IFREG|0644, st_size=1809, ...}) = 0^M
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xb77a2000^M
read(3, "# genesys.conf: Configuration fi"..., 4096) = 1809^M
open("/dev/bus/usb/001/003", O_RDWR)    = 4^M
ioctl(4, USBDEVFS_SETCONFIGURATION, 0xbfbd14a4) = 0^M
ioctl(4, USBDEVFS_CLAIMINTERFACE, 0xbfbd14a4) = 0^M
read(3, "", 4096)                       = 0^M
close(3)                                = 0^M
munmap(0xb77a2000, 4096)                = 0^M
open("./genesys.conf", O_RDONLY)        = -1 ENOENT (No such file or
directory)^M
open("/usr/local/etc/sane.d/genesys.conf", O_RDONLY) = 3^M
fstat64(3, {st_mode=S_IFREG|0644, st_size=1809, ...}) = 0^M
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xb77a2000^M
read(3, "# genesys.conf: Configuration fi"..., 4096) = 1809^M
read(3, "", 4096)                       = 0^M
close(3)

I'm not sure if that looks correct.
