I'm having an issue with two different Kubios chest strap devices that I have data to retrieve from. The first stopped being recognized at all as a device, won't even recognize being put into its base, but will when it's turned on first. In the latter case I get the "USB malfunction" error. This is the case on any computer. It isn't the cord or charging base, other monitors light up in it. I switched to another one I haven't been using, along with its own base & cord, used it for one session, and it lights up when put on the base unlike the other one but still gives me the same error on the computer.

Has anyone experienced this or have any advice? ALSO, is there any way to transfer files from the device to a Bluetooth enabled computer so I can get my data? Googling is no help because it all addresses problems on the computer rather than the device itself being the problem.
