Yes, it does work for me to use modprobe with the 3006 device. I can use either the 3000 or 3006, but not both at the same time.
But if he wanted to use a mix of the 3000 and 3006 devices it would not work?

Hi, Mark.
I think it would work, maybe even in an older kernel, assuming the
ftdi_sio module knows about the chip type of the device, and all 18
devices have product ID 0x3006, and they are the only devices for which
the ftdi_sio module will be used that it doesn't know about (due to the
limitation of only being able to specify one vendor-product modprobe
parameter pair which will have to be set to "vendor=0x104d product=0x3006").
The device with product ID 0x3006 works for you in your Fedora 2.6.35
kernel by specifying the "vendor=0x104d product=0x3006" modprobe
parameters, right? So then the only question would be whether it would
correctly add the additional /dev/ttyUSB* device files, which I think it
would, given Guy's explanation of what's going wrong.
