在Ubuntu 13.04中,我對CDMA調制解調器寫的udev規則是 SUBSYSTEM=="tty", ATTRS{bInterfaceNumber}=="00", ATTRS{bNumEndpoints}=="03", ATTRS{product}=="ZTE CDMA Tech", ACTION=="add", SYMLINK+="CDMAModem"
udev規則無法正常工作
和
$ sudo udevadm info -a -p $(sudo udevadm info -q path -n /dev/ttyUSB0)
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

哪兒我去錯了嗎?當我插入調制解調器時,我不會得到/dev/CDMAModem
。我也試過NAME
而不是SYMLINK+
。 /dev/ttyUSB0
是我連接調制解調器時獲得的設備文件。我也得到/dev/ttyUSB1,2,3,4
,但他們沒有迴應AT命令。
stackoverflow說要添加一些更多的細節,因爲我的問題主要包含代碼,所以我輸入這個。我找不到任何我可以提供的進一步細節。
如果使用'udevadm --monitor'(關閉我的頭頂部,將會回到正確的是這是錯誤的),並且插入設備,您是否在輸出中顯示添加事件? – jam
Thanq我會檢查它。 – neckTwi
它說'〜$ sudo udevadm --monitor udevadm:無法識別的選項'--monitor'' – neckTwi
