下图是我的接线图
下图是我的PCB图,PCB是六层板、

您好,
看您的现象描述像是PCB layout 问题,我已将您的问题发布在E2E英文论坛,看那边的工程师对您的PCB layout 有什么comments,帖子链接如下,您也可以关注帖子,以方便查看或追问后续疑问。
E2E英文论坛工程师已回复:
Could you clarify what is meant by the computer not being able to recognize the board? Is this during the schematic design/layout phase, or has the design already been fabricated and cannot linkup?
您能否说明电脑无法识别主板的含义?这是在原理图设计/布局阶段,还是设计已被制造,无法连接?
当把单个dp81848电路拿出来制版后是能够连接电脑的
在这种情况下测试848时,848是与主板完全分离的板子,还是用作互连?
您是否能够读取PHY寄存器并为每个案例提供(0到1E)的寄存器转储?
