5.4 USB Connection Problems
Symptom:
1. Some customers report that the USB cannot be detected by computer when the USB
cable is connected and the plotter is turned on.
2. The USB port can only accept the original port that USB driver was installed. If user
connects USB on other USB port, then the computer cannot recognize it or will ask to
install driver again.
Solution:
Make sure that users install latest GCC USB driver. The latest USB driver can be downloaded
from GCC Club. After installation, computer can detect USB connected when plotter is on and
the USB cable is connected to computer.
When the USB driver was installed on one USB port and then the USB cable is re-connected
to another USB port on the same PC next time, most of computers will show the icon and will
ask user if they want to install USB driver again.
(In the bottom right corner of the screen by the clock (list of programs running) you will find
this icon below:)
But sometimes for some computers (laptop mostly), there is no reaction when the USB cable
is connected and the icon cannot be found in the bottom right corner of the screen. From GCC
experience, these computers may have hardware problem or the computer has virus and
cannot detect some new USB components.
If there is no reaction when the USB cable is connected, you can follow below steps to install
the GCC cutter.
