4b的两个usb3.0是独立的么

[shengxia]

我测试了一下，没办法两个usb3都跑满带宽

[大法师]

@shengxia 是独立的。

[shengxia]

@大法师 4b上边这个usb3.0的端口是不是默认是otg模式？
这块我不太懂哈。我自己的测试是：
1 我是连接的海康工业相机，相机接口是micro usb3.0
2 使用一个micro usb3.0转typec （母口）
3 最后就是一个typec 转 公口a的 线

试了一下
1 如果typec线是连接在下边这个usb3.0口上，我typec口正反 出现的是 high speed 和 super speed，所以我只要确保正确的typec插入面就行
2 但如果typec线是连接在上边这个usb3.0口上，我发现正反出现的，一面完全识别不出来（是不是就是走在了otg模式下？），另一面就是high speed。

我期望的是 上边这个也能super speed。

是不是需要做些设置？也就是默认上边这个也在host模式下。

[大法师]

@shengxia 默认配置是host模式。正反插提供dmesg 日志看看，另外插拔重新识别有无变化，也可以再试试单独U3 U盘在上层端口能不能识别到super speed

all recognized but all is highspeed(usb2.0)

[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

@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。

[george]

@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!
