什么是USB错误-62？
提问于 2016-03-24 20:55:30
当我将USB鼠标插入计算机时，日志中会出现以下错误：

确实有一个内核错误代码列表，根据系统的设置方式，您应该在/usr/include/asm-generic/errno.h中找到这些代码。要查找错误62，只需运行：
$ grep '62' /usr/include/asm-generic/errno.h
#define ETIME 62 /* Timer expired */要浏览100多个错误代码的整个列表，请尝试：
cat /usr/include/asm-generic/errno.h | less这将为您找到USB设备故障的原因提供一个起点。我怀疑硬件(USB设备)在连接方面是错误的，内核只是在尝试运行设备= Error 62时超时。
