如何访问uclinux中的usb海量存储设备.？

Question

我有关于usb的内核日志，但是如何访问它。/dev中没有设备注册..？怎么弄到这个..？和配置的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)，在"SCSI设备支持->“启用"SCSI磁盘支持”下启用"USB海量存储详细调试“

@Amar，在内核日志中，将查找ex文件系统中连接到USB大容量存储设备的位置的信息:它可以是sda，也可以是sdb或sdc。检查并使用挂载命令挂载USB大容量存储sudo mount /dev/sd* <Path where you want to mount USB device>和之后可以访问USB大容量存储。下面是关于USB大容量存储连接到何处的内核日志信息。

在本例中，根据您感兴趣的分区，安装/dev/sdc4 1或/dev/sdc4 2或/dev/sdc4 3或/dev/sdc4 4分区。
