I have two Block Erupter Sapphire and one Antminer UT, using XP Pro SP3. I can plug in any combination of TWO of these ASICs but when I plug in the third one, it doesn't matter which one, Windows virtually unplugs the second one and puts a ! on the third one.
Properties on that 3rd device (doesn't matter which one) says it's a duplicate device. I have tried all the possible orders of plugging them in, into the same hub, some into the hub and some into ports directly on the PC.
Doesn't matter how they're plugged in, the third always knocks out the second and itself.
