当我插入和拔出电源时，系统看到有东西插入：
bluehat@Matapan:/dev$ tail -f /var/log/syslog Mar 23 15:36:35 Matapan kernel: [156082.112874] usb 7-1: new full speed USB device using uhci_hcd and address 6 Mar 23 15:47:19 Matapan kernel: [156726.248081] usb 7-1: USB disconnect, address 6 Mar 23 15:47:29 Matapan kernel: [156736.200148] usb 6-1: new full speed USB device using uhci_hcd and address 3
AVRISP MKII应该依靠cdc-acm：
bluehat@Matapan:/dev$ modinfo cdc-acm -V module-init-tools version 3.12
因此它应该能够很好地看到它，但是我无法写它。
avrdude -p m1280 -c avrispmkII -P usb -U test.hex
退货
avrdude: usb_open(): cannot read serial number "error sending control message: Operation not permitted" avrdude: usb_open(): cannot read product name "error sending control message: Operation not permitted" avrdude: usbdev_open(): error setting configuration 1: could not set config 1: Operation not permitted avrdude: usbdev_open(): did not find any USB device "usb"
事实证明，Ubuntu会承认对象存在，但在修复某些udev规则之前，它并不能很好地发挥作用。多亏了http://steve.kargs.net/bacnet/avr- isp-mkii-on-ubuntu-hardy/，该文件提供的文件只需要稍作更新即可。
创建新文件/etc/udev/avrisp.rules
SUBSYSTEM!="usb", ACTION!="add", GOTO="avrisp_end" # Atmel Corp. JTAG ICE mkII ATTR{idVendor}=="03eb", ATTR{idProduct}=="2103", MODE="660", GROUP="dialout" # Atmel Corp. AVRISP mkII ATTR{idVendor}=="03eb", ATTR{idProduct}=="2104", MODE="660", GROUP="dialout" # Atmel Corp. Dragon ATTR{idVendor}=="03eb", ATTR{idProduct}=="2107", MODE="660", GROUP="dialout" LABEL="avrisp_end"
现在创建一个到文件的虚拟链接并为其赋予规则优先级
cd /etc/udev/rules.d sudo ln ../avrisp.rules 60-avrisp.rules
检查您是否在拨出组中
groups
重新启动udev
sudo service udev restart
万岁！
