Daisy chaining mixed connectivity drives
I have an iBook (OS X 10.5.8 Leopard) with 2 USB 2.0 ports and a Firewire 400 port. The USB ports are in use, as is a hub plugged in one of them. I have a CalDigit AV drive connected to the iBook via a Firewire 400 - Firewire 800 cable. The drive also has an additional Firewire 800 port and a USB 3.0 port.
I'm wondering if a USB 3.0 drive can be daisy chained to the CalDigit drive through the USB 3.0 port, even if it is connected to the computer via Firewire 400. If this is possible, I realize I would only get Firewire 400 speed, which is okay.
Or do I need to find another Firewire drive to daisy chain?
Thanks
iBook, Mac OS X (10.5.8)
