@george 这个huggingface上有兄弟上传了，我下载用了没问题

我自己是了一下qwen1.8b,是没问题的，但是换了4b会提示要升级npu驱动，

然后我看到官方的仓库里有放出npu driver，就是不知道如何可以在板子上，直接编译，安装的方法

@大法师 OK，这个特性能够在下次新的img里默认打开测试一下么，我感觉这个还挺有用的，不用受限于周围网络环境。

我自己的jetson设备上使用手机的USB网络共享是可以给设备分享网络的（手头有多余的5G手机，Android系统）

但是我在coolpi4B，ubuntu22.04下试了一下，看了下貌似4b只会识别为普通usb设备。

在手机上 切换传输文件和USB网络共享，dmesg输出的都一样：
[ 865.224942] usb 5-1: new high-speed USB device number 3 using xhci-hcd
[ 865.369388] usb 5-1: New USB device found, idVendor=04e8, idProduct=6860, bcdDevice= c.00

[ 865.369403] usb 5-1: Manufacturer: SAMSUNG
[ 865.369406] usb 5-1: SerialNumber: RFCN3006XPH

是不是当前ubuntu22.04没有开启相关能力？

@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 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。

@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。

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

all recognized but all is highspeed(usb2.0)

@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。
