Original description

Arduinos equipped with the Atmel16u2 for USB communications
do not exhibit the behavior of a properly installed COM port.

It's likely this affects all devices not equipped with the
FTDI USB serial converter chip, though I can't confirm if
the bug is expressed on e.g UNO R1/R2, or newer Windows
(that may have an updated 'usbser' driver).

What steps will reproduce the problem?

1. Attach an UNO R3 to USB on a WinXP box.
2. Probably affect all the Atmel8u2/16u2 USB programs.

What is the expected behavior ?

Expected DBT_DEVICEARRIVAL.DBT_DEVTYP_PORT (e.g 'COM7')
This is the notification for a properly installed COM port,
whether it's physical or virtual.

What do you see instead ?

Only DBT_DEVICEARRIVAL.DBT_DEVTYP_DEVICEINTERFACE
?\USB#Vid_2341&Pid_0043#749343030303517191D0
#{a5dcbf10-6530-11d2-901f-00c04fb951ed}
This is merely a raw USB device with no specific properties.

What version of the Arduino software are you using?

Affects all versions I've checked.

On what operating system?

Misbehavior present on WinXP, can't confirm other versions.

Which Arduino board are you using?

Duemilanove, Nano, and UNO R3
The bug is present with UNO, not with 2oo9 and Nano.
