I requested Mike Lee’s help to buy a USB Hub. Though I found out 4 USB ports mounted on my notebook is still insufficient for me, I would rather get another USB HUB by Logitech.
RM 49.00 from Thunder Match Technology, Low Yat.
Comes with USB cable to connect to PC and Quick Start Guide.
Green LED indicator when connected to PC.
So I’m left with 3 USB ports now (3 on notebook and 1 on the hub).
