I want to use my bluetooth E815 phone with my USB2.0 PC, does it matter for the phone if the dongle is USB 1 or 2? Will getting a USB1.0 dongle be too slow for DUN with the 815.
Also I know that the phone only support up to 30 feet, so Bluetooth Class 2 should be fine, but what about the Bluetooth version? Should it be BT version 1.what, v2.0? I know that BT v2.0 has less energy required from the laptop, so that would be good. I don't want to underbuy, but I also don't want to buy more than I'm going to use. Thanks!
