Description
It appears that the driver for the arduino micro fails intermittently. I get the error message "Windows has stopped this device because it has reported problems. (Code 43)". At the point I took the screenshot I had 3 arduino micros plugged into my computer, 2 of which showed up as COM ports and 1 of which shows as an unknown device.
The number of arduino micros that windows recognises has varied over time so I don't think that this is a hardware error.
I am running arduino 1.5.8 on windows 7 64 bit. I have installed the latest drivers available.(I attach a screenshot of me looking at the driver update).
Background: I am polling a pressure sensor over I2C and streaming the data back to a windows PC.

Research direction
The report concerns intermittent Arduino Micro USB/COM-port enumeration on Windows 7 64-bit with Arduino IDE 1.5.8. Start by reproducing it with multiple Micros and the described I2C pressure-sensor setup, then inspect the attached screenshots and driver state; done means each board consistently appears as a COM port.
