32位单片机之D12枚举求助
使用D12芯片，相同的程序。
若CPU为AT89C52或SST89C54，则可成功枚举； 若CPU为Motorola ColdFire 5282，则GoodLink闪烁三次后熄灭，计算机提示为Unknown Device。此时用bushound抓取的序列如下： Device - Device ID (followed by the endpoint for USB devices) (11) USB Root Hub (12) USB Root Hub Phase - Phase Type CTL USB control transfer DI Data in LEN Data length Data - Hex dump of the data transferred Descr - Description of the phase Cmd... - Position in the captured data

已成功实现枚举，系统提示需要驱动程序。
但产生新问题：用WinRT观察，本USB设备的地址居然为0！！ 哪位大侠指点一下迷津？ |
