Sorry, saying good-bye to the ICE is part of the normal
communications protocol, and will not be dropped from
AVRDUDE.  If it annoys you that this causes the ICE to
also say good-bye to the USB, and reconnect to it (causing
a noticable delay on any operating system I've seen so far),
then please talk with Atmel so they change their firmware,
or at least make that (IMHO unnecessary) action optional.

Avrdude Version: 5.5
OS: Debian Etch

When i try to call the avrdude 2 times directly after each other like this:

#avrdude -p m88 -c jtag2isp -B 10 -P usb&&avrdude -p m88 -c jtag2iso -B 10 -P usb

the second call fails with the error:

#avrdude: usbdev_open(): did not find any USB device "usb"

In the system log you can see that the JTAG ICE mkII is disconnected from usb after the first call.

By looking into the source code of jtagmII.c i indentify that the disconnect is caused by command CMND_SIGN_OFF int the function jtagmkII_close.

By adding a new close funktion without CMND_SIGN_OFF for jtag2isp the Programmer works fine.

Reagards, Arnd
