sdk8.0 u***配置为host接口，下边接hub芯片，使用fdisk -l命令查看无U盘信息，请问是什么原因？

3844 接口

问答对人有帮助，内容完整，我也想知道答案 0 本帖最后由一只耳朵怪于 2018-6-5 09:35 编辑使用sdk8.0，u*1配置为host接口，下边接hub芯片。遇到的问题是，在系统启动之前插U盘可以识别，启动后，拔掉U盘有打印信息，但是再插上就没有反应了。使用fdisk -l命令查看无U盘信息。背景：同一块板子，使用之前的4.6的sdk一切正常。所以可以排除硬件问题。能否给个调试思路？？ linux启动部分log信息如下： [ 2.374847] rtc-pcf8563 2-0051: setting system clock to 2015-03-20 11:18:33 UTC (1426850313)[ 2.386963] ALSA device list:[ 2.390099] No soundcards found.[ 2.572839] u* 2-1: new high-speed USB device number 2 using mu*-hdrc[ 2.653262] kjournald starting.
