Using the HDD Case as a USB Hub (RX-35U3 Only)
This chapter describes how to connect the on-board USB hub of RX-35U3
to another USB device or USB hub.
USB devices may be connected in a tree structure (USB Bus Tree) with one
host computer as its starting point (root), and one USB bus tree may support
up to 127 devices. A USB hub is counted in the tree as one of the 127
devices. While providing additional ports for these USB devices, a USB
hub also supplies power to the attached devices. In one USB bus tree, USB
hubs may be cascaded up to 5 levels (or 6 levels including the root hub).
Please firmly plug the USB connector of the USB peripheral device into the
downstream port (Type A Connector) on the RX-35U3. The time your PC
requires to detect the USB peripheral device may vary with each PC
environment. If your PC does not detect the USB device after several
minutes, please re-insert the USB device into the USB Hub. For details on
installation procedure of the USB peripheral devices, please refer to the
user's manual for each USB device.
There are two patterns for connecting two USB hubs to each other:
"cascading another USB hub to RX-35U3" and "cascading RX-35U3 to the
other USB hub."
●
Cascading RX-35U3 to another USB hub
Using a USB cable, connect the downstream port (Type A connector) of
RX-35U3 to the upstream port (Type B connector) of the other USB hub.
●
Cascading another USB hub to RX-35U3
Using a USB cable, connect the upstream port (Type B connector) of RX-
35U3 to the downstream port (Type A Connector) of the other USB hub.
Note: When cascading two or more USB hubs, be sure to attach the
included AC power adapter to RX-35U3.
