我有内核日志，它说有关 USB，但如何访问它。/dev 中没有设备注册..？如何访问这个..？ 并配置和 anabledin 内核
在“设备驱动程序”下
在“USB 支持”下 启用“USB 海量存储支持” (可选)启用“USB 海量存储详细调试” 在“SCSI 设备支持 -->”下 启用“SCSI 磁盘支持”
usb 1-2: new full speed USB device using lpc178x-ohci and address 2
usb 1-2: New USB device found, idVendor=8564, idProduct=1000
usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-2: Product: Mass Storage Device
usb 1-2: Manufacturer: JetFlash
usb 1-2: SerialNumber: 74O2LC2HD514SCME
最佳答案
@Amar，在内核日志中，将找到有关插入的 USB 大容量存储设备在文件系统中附加到何处的信息，例如:它可以是 sda 或 sdb 或 sdc。检查并使用mount命令挂载USB大容量存储sudo mount /dev/sd* <Path where you want to mount USB device>然后您就可以访问 USB 大容量存储设备了。以下是有关 USB 大容量存储连接位置的内核日志信息

在这种情况下，挂载/dev/sdc1 或/dev/sdc2 或/dev/sdc3 或/dev/sdc4 分区 取决于您感兴趣的分区。
