T113-S3 一个很奇怪的USB问题

主控芯片为T113-S3,在Linux内核初始化的时候,总是会提示USB错误。百思不得其解,已经调试三天了,特来社区向大家讨论。

附上主要log信息:

Re: T113-S3 一个很奇怪的USB问题

简单分析一下问题,我的T113-S3,通过CH334 USB HUB芯片将USB1扩展成了四路,分别外接了移远EC20、USB有线网卡SR9900A;但是在插入电源自动开机的时候,总会出现USB错误,但不知道是系统的问题还是硬件设计的问题。
目前怀疑的问题如下所示:
1. 5V供电不足,5V供电采用的SY8303AIC只有3A的电流供电,理论上是够了,但是EC20在3.6V电压域峰值电流可以达到2A,是不是这里突然拉低导致初始化失败了呢?(其实我觉得不太可能是这个问题,因为我用示波器触发档位去测量,没有看到电压低于4.9V)
2. USB走线干扰问题,在PCB上5VDCDC的连线和USB的连线重复了一段,可不可能是这个问题引入了DCDC的噪声呢?
3. USB阻抗问题,可能90欧姆双端阻抗不稳定,导致通讯失败? (可是他有时候又能成功)
神奇的测试:
   为了排除上述的问题,我通过外部电源直接给5V供电,发现好像这个问题没有出现了,现在让人更自闭了……

Re: T113-S3 一个很奇怪的USB问题

大概率还是电源问题,可以试一试4G模块单独供电先试一试。

目前的4G模组已经是单独供电了 哈哈,我把原理图附上

主要不知道是什么缺陷,无从下手了,不确定是电源带来的干扰 还是其他的干扰

用芒果开发板 + USB HUB 试一试,
如果还不行,那怀疑是不是USB端点不够?

没找到usb_otg这个变量,在内核设备树里关于usb0的是这样的,usb_port_type = 0已经算是device了,但调适口还是有那些信息。
