Well, I now have one. I should be getting scans of it reasonably soon. The 
phone end of the cable is marked N-5100; oddly, that seems to be the only 
mention of what kind of phone it's for...

The plastic box the PCB is inside has a space for a switch, marked L and R, 
but there is no switch there and there are no pads on the PCB for 
installation of one. I suspect someone's been saving money.

Here's the PL2303 data sheet:


I can't tell whether my device is set up for 5V or 3.3V; I'll just have to 
plug it in and measure it. Is it known that the E2 *doesn't* work with 3.3V? 
And what's the modification I need to do?
