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.
