Cannot detect usb flash drive

I am having 1 acer 4752z with Win 7 HP, and 1 unknown branded usb flash drive. Now my problem is the laptop cannot detect that unknown flash drive but can detect all other flash drive i got in hand which are Kingston datatravelr and Adata. Thus, i thought the brand-less flash was malfunction but when i plugged it into other pc and laptop, they can detect it and fully functioning with no problems. How could this happen? my acer 4752z cant even detect it in the bios, but others can. Can anyone help to resolve this mystery?

Sorry for my poor english and thanks for reading and helping if any...
