Well I suspect it is one of two problems, firstly the driver is no
working with the device,  or udev is misconfigured and is not creating
the nodes.  Try creating static device nodes. i.e.

# mknod /dev/ttyUSB0 c 188 0
# mknod /dev/ttyUSB1 c 188 1

If it is a udev problem then creating static device nodes should work.

I agree this tends to suggest it is not a device problem but I don't
have any devices using a usb-to-rs232 interface so I can't tell you what
you should find see in the logs.  I presume when you type

# lsmod

visor is listed.
