Type-A connector and a screw on the Type-B connector.
Every time you plug in and plug out the cable from the host computer,
always press both latches and then plug the connector into the USB
sockets on your computer or vice versa.
Plugging in the cable to the host computer:
Step 1: Press both latches.
Step 2: Plug in.
Plugging out the cable from the host computer:
Step 1: Press both latches.
Step 2: Plug out.

NOTE
The latch is designed to lock to most of the computer USB
sockets
; however, some sockets may be designed with a slight
margin difference
, which may cause the latch not to lock to
properly to those USB sockets.
Plugging in the USB cable to the UPort 400A hub:
The bolt on the side of Type-B connector is for fixing the cable firmly to
the UPort 400A USB hub. Remember to swivel the bolt after plugging in
and before pulling out the connector.
Step 1: Plug the USB cable type-B plug into the type-B socket.
Step 2: Turn the bolt on the type-B plug clockwise for about 5 turns.
Plugging out the USB cable from the UPort 400A hub:

FAQ
Q:
Does the UPort™ 400A require a software driver?
A:
UPort™ 400A is USB
-IF certified; it works with major operation
systems and does not require an additional driver.

- 13 -
Q:
My device is USB 2.0 compatible. Will the UPort 400A work
with my device?
A:
The UPort 400A is a USB 3.2 Gen 1 certified product; therefore, it is
downward compatible to USB 2.0 and 1.1.
Q:
How many USB devise cascade can the UPort 400A support?
A:
Five
layers. By definition, the USB-IF should have seven layers of
USB device cascading
. The host computer and the UPort 400A have
each taken one layer already
; therefore, five layers remain
available for cascading. There are some cases
where the host
computer design may take more than one layer
and so the
availability of the cascading layers may vary.
Q:
When I plug my USB device
into the UPort 400A, why
cannot
it
be detected by the host computer or recognized as an
USB
2.0 device
?
A:
The UPort 400A is USB-IF certified (USB-IF TID: 7623 for UPort
407A,
7624 for UPort 404A); however, interoperability issues can
still arise
among devices made by different manufacturers. The
chance of this happening is higher if
your USB device is not USB-IF
certified as over/under SPEC design.
1.
Please ensure the UPort 400A is recognized by the host
computer first.
2.
Plug your device to different USB port on the hub to rule out
USB port being damaged.
3.
Please check if it is a cable-related issue; change to a different
cable to rule out a broken cable issue.
4.
Unplug the USB device or restart the device in computer
management like Windows Driver Manager.
Q:
What is the output power of each port?
A:
Port 1 provides
1.5 A if your USB device supports BC 1.2;
otherwise, each port provides 0.9 A power.
Q:
What is BC 1.2 shown on port 1? What does it do?
A:
BC 1.2 AKA Battery Charging v1.2, defined by USB-IF, is designed
to charge mobile devices and support up to
1.5 A if the mobile
device supports CDP or DCP mode.
Q:
If overcurrent happens, what should I do?
A:
When overcurrent protection LED is on, it means the downstream
device is drawing power over the USB port's limit. Please remove
the downstream USB device from
the UPort 400A and unplug the
upstream USB cable or power source
. T
he UPort 400A should return
to normal state. Ple
ase check your downstream USB device to
make sure it is not
malfunctioning, and the design is within USB-IF
specification, and re-plug in to the UPort 400A.
