しかし、Debianでは、次のコマンドでnadaを取得します。 -
[$] udevadm info -a -p $(udevadm info -q path -n /dev/sdb)|grep -iE "manufacturer|product"
[$]
新しい質問でこんな質問をしてくれてそうしました。
モニタコマンドを使用すると、udevadmからいくつかの出力が得られます。
[$] udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

製造元と製品情報を取得する方法を学びます。または、再構築された可能性があります。
コマンドの一部はいくつかのタスクを実行します。
[$] udevadm info -a -p $(udevadm info -q path -n /dev/sdb)
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.
