3588 linux USB 接口识别 U 盘失败
本帖最后由 alive 于 2026-7-15 20:45 编辑刚开机时插入 U 盘有时可以识别，有时不能识别。一直使用的是同一 U 盘。
识别成功的情况下，执行 sudo udisksctl unmount -b /dev/sda1安全弹出 U 盘，等待 5s 后拔出 U 盘。
再等 15s 左右后又插入同一口可以识别。再次执行 sudo udisksctl unmount -b /dev/sda1 等待 5s 后拔出 U 盘。
再等 15s 左右后插入其他口，不能识别。
这是最后一次拔出 U 盘，再插入的 dmesg

到这就没有反应了，等很久也没有识别到 U 盘。
这是可以识别时log。

在弹出U盘的时候试试运行sudo udisksctl power-off -b /dev/sda切断U盘的电源，等待几秒再重新插入试试 Glucose 发表于 2026-7-20 14:55
