Trouble Shooting 

Q1: Can I connect or disconnect devices while the 

computer is powered? 
A1:  Yes, you can connect or disconnect any USB cable 

or devices, because USB is supporting Plug & Play 

and Hot-Plug. 

 
Q2: Can I use my old USB 1.1 devices with the USB2.0 hub? 

A2:  Yes, you can. USB 2.0 is downward compatible to 

USB 1.1, but please note, you can use only Low-

and Full speed (1.5 / 12Mbps) with these units 

 
Q3: Can I use USB 1.1 cable to connect the hub and 

devices? 
A3:  Yes, you can, but it may cause connection 

problems by connecting USB 2.0 high speed 

peripherals. Therefore it is recommended to use 

only certified USB 2.0 cables.
