Never mind the CX4200 bit.  The DX4200 and DX4250 all have the same USB
product ID and can be considered one and the same thing.

Weird.  Can you provide a log?

  # SANE_DEBUG_DLL=127 SANE_DEBUG_EPSON2=127 scanimage -L

might be able to shed some light on this.

BTW, you're doing all these tests with administrative privileges
(i.e. using `sudo` or as root), right?

Hope this helps,
