4b的两个usb3.0是独立的么

shengxia

补充一下
1 为了排除供电问题，我有插在可以独立供电的hub上，效果是一样的
2 我昨晚往sd卡刷了全新的6月的ubuntu22的系统，进去后试了一下，连我的nvme转usb这个，一面直接没法连接，另一面试了几次，最终也无法连接

大法师

@shengxia 建议U3设备直连测试看看情况。外挂转接NVME有供电要求

shengxia

@大法师这里主要是同样的设备，线材，下边这个是没问题的，就只有上边这个有问题呢。所以我理解没必要单独找一个设备吧，我海康的直连我也是试过的。现象是一样的。

PS：百度网盘里的ubuntu系统我试了一下密码貌似都不是coolpi诶，我是后来用emmc系统进去后，然后chroot了一把sd的改了一下密码。

大法师

@shengxia 新打包的ubuntu系统密码123 用户名coolpi

USB移动硬盘插入上层U3端口

可以替换试试
4b内核驱动安装包

@大法师嗯，我其实内心里是知道上下应该没啥区别的，但我这个板子的确上边这个表现很奇怪，我刚和客服说寄回去，让售后工程师辛苦看下了。我本人对这块没啥经验，也就只有简单的排查能力。

@shengxia 昨天有提交了一个USB3.0的修改，你可以同步最新代码测试。我手上几个盘都可以使用。

大法师

@shengxia 你的主板我们同事看了，usb3上下层端口都没有问题。用相同的tf卡openkylin系统加usb nvme、usb ssd测试都可以识别到super speed。需要注意部分型号nvme转接板有自动休眠功能、供电需单独5V/2A

(你寄的nvme转接盒没有带盘)

shengxia

@大法师能用Ubuntu22 或者ub20那个镜像测一下么？我主要用ub环境开发哈

大法师

@shengxia ok!
