Q: When I plug my USB device into the UPort 200A, why cannot
it be detected by the host computer or recognized as an USB
2.0 device?
A: Interoperability issues can arise among devices made by different
manufacturers. The chance of this happening is higher if your USB
device is over/under SPEC design.
1.
Please ensure the UPort 200A 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 in 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: What if I require a USB hub with a firm cable connection and
higher protection level?
A: You may consider the UPort 400A Series that comes with a latching
cable. The UPort 400A also comes with surge level 3 protection,
providing you peace of mind in terms of reliability.
