更换FT4232芯片之后ADC12DJ3200EVM板卡遇到USB连不上的问题

Other Parts Discussed in Thread: ADC12DJ3200, ADC12DJ3200EVM

由于某些意外怀疑EVM上的FT4232H 片子坏掉了,所以换了一片上去。焊接没有问题,新的芯片连上USB之后电脑发现新设备,驱动安装正常,GUI软件无法连接板卡。查看troubleshooting,看到下面一句话。

Use the free FT_PROG software from FTDI chip and verify that the onboard FTDI chip is programmed with the product description ADC12DJ3200_A0。

用FT_PROG看了一下,FT4232H的片子能看到,但是product description不是ADC12DJ3200_A0。怀疑是不是新的片子的e2prom需要烧写一个专用的固件。可是TI网站上没有提到这个文件。请求帮助或指点,谢谢。
