TUSB9261 电脑无法识别

TUSB9261: 可以正常烧录 ，无法识别硬盘

? ?
Part Number: TUSB9261

目前 

TUSB9261  可成功少些固件，单是无法识别硬盘。 使用单5V供电，硬盘链接的是MSATA 。

    您好，mSATA也是SATA，只是使用的一种较小的connector，所以TUSB9261也是能够兼容的。

    关于无法识别的问题，您参考下面这个帖子，和您的问题类似：

    目前的固件版本是否正确？TUSB926x_FW_v1.06.hex

    是否可以保留一个联系方式电话沟通。

    您好，是在产品在主页的“软件开发”这里下载的固件吗？

    您好，我下载了这个固件，并安装，里面有两类。

    一个是TXP和TXM极性相反的，一个是极性没有相反的，您要确认下您的电路中极性是否相反，如果相反选择polarity swap部分的，如果极性没有相反，选择No Polarity swap的固件，所以这个需要注意。
