I have a tablet with single USB port and I don't want to carry a USB hub with me, so, I need a mouse that will work without using my single USB port. My tablet has Bluetooth 4.0 built-in.
Ok, I found a mouse for myself: http://www.ebay.com/itm/iBUFFALO-Bluetooth4-0-BlueLED-mouse-with-USB-adapter-Silver-BSMBB09DSSV-New-/281530781966
And I like it, aside of one thing - it has some USB adapter included. I asked the seller about that, and..., I think there are two options: The mouse does not work without that USB adapter or The seller does not know English well and answered as he can.
My conversation with him:
Me: Hello. Could you tell if this mouse need it's own USB adapter inserted into PC's USB, even if the PC already has Bluetooth? I have a tablet with single USB port and I don't want to occupy it with mouse, so I need the one which will work without any USB adapters. Thank you. Seller's answer: It has USB. Me: Sorry, I asked not that. I asked if this mouse need to use own USB adapter that comes with mouse. I will try to show a scheme. Mouse <--------------> USB adapter <---> PC without Bluetooth = Working Mouse <--------------> PC with Bluetooth = Working? Seller's answer: It cannot be use without the adapter.
But I think it's weird to write that this is BT mouse, if I can't use it with built-in BT, instead of that USB dongle from package.
