Not sure where you are located. Maybe India? Isnt that where tech support usually is?
Anyway.. I recently purchased a Logitech Marathon mouse, http://www.logitech.com/en-us/mice-pointers/mice/devices/marathon-mouse-m705, and a HP Wireless Elite v2 keyboard, http://www.amazon.com/HP-Wireless-Elite-Keyboard-V2/dp/B005HNHRA6/ref=pd_cp_pc_0. Both have that tiny USB that connects it wireless to the computer. The keyboard has this thing called Link-5 which connectes different devices to other devices. The mouse has something called "Unifying" that I am not sure but might only be supported by Logitech. If so that kind of answers my question.
Anyway, Does anyone have experience with either connection software/devices that can help me figure out a way to only use one receiver for both my keyboard and mouse?
