解决方法
@H_404_11@ 插入你的设备,然后看到syslog:$tail -n 2 /var/log/syslog
Dec 22 17:25:14 localhost kernel: [73348.931267] usb 2-3: new high speed USB device using ehci_hcd and address 13
Dec 22 17:25:14 localhost kernel: [73349.084555] usb 2-3: configuration #1 chosen from 3 choices
注意那里的设备总线ID:usb 2-3.
现在获取版本:
$cat /sys/bus/usb/devices/2-3/version
2.00
