, Thanks for the reply.
I have tested al the USB ports on my 3 Asus laptop and below are the results.
Asus Zenbook UX434FLC_UX433FLC -- able detect
Asus E203MAS_E203MA -- unable detect
Asus G56JR-- unable detect
FYI, all 3 laptops are in Windows 10 64 bit.
Any idea why only Zenbook able to detect it ?
Thanks in advance.
