這是NV devkit還是custom board?

4

我们自己板子，就这几台设备有问题，其他客户没有反馈过此问题

5

建議在NV devkit上確認一下是device的問題還是usb host本來就不穩定

6

这是客户现场的，本地都没办法复现，这个log是硬件断开的，还是软件导致的

7

那個disconnect又重新出現的秒數不太像是人工手動插拔的

但從這些log沒辦法準確判斷到底出了什麼問題

8

哦哦，那有没有什么好的办法去debug这个问题呢，只有在客户现场在会遇到这个问题，本地没有复现到此问题

9

基本上看你們在客戶現場能做什麼測試. 比方說能抓usb bus trace嗎?

不能做的話基本上這個問題不可能找到原因.

11

usb bus trace 怎么抓呢，有没有什么方法，谢谢

12

Need to connect such device to your device side and Jetson.
