CyberShot DSC-S40 and FreeBSD

[Mikle]

Hello, list!
Is anyone here using CyberShot DSC-S40 with FreeBSD?
It's pretty old camera. When i plug it in my BSD desktop, nothing happens - e.g., even no dmesg messages. Also, gphoto2 gui (gtkam) tells me 'no cameras detected' when i try to detect it.
As i understand, i need some specific kernel module (via google i've found that that's umass, which i have compiled-in in my kernel)
What could i do to detect what has happend?

Wbr,
