[746]

hi ! i have an asus x55c-sxo78d laptop . i have difficulty in using the keyboard and mouse ,so i bought a combo of wired usb keyboard+mouse. i also have a usb modem for internet connection . when i plug in the usb modem , it is impossible to plug in any other device because it is very big. so, i bought a cheap usb hub called tricom usb hub which has four ports. after a week three of the ports stopped working and the other one does not have enough speed.what can i do? i don't want to buy anything new because i have spent all my money. how can i fix the hub?this is the picture of the hub below. can i make a wireless usb hub?
I DONT HAVE ANY WIFI ADAPTERS OR BLUETOOTH DONGLES OR SUCH THINGS.
can i make the modem which is dial-up&vpn to plug and play?

Before buying any USB device, see to it that it is compatible with your device, like the speed and version. I suggest use other USB ports of the laptop for USB modem. This will allow faster operation than that hub of yours. Take note that the two of the four wires of the USB have 5 volts in it DC.
