HI-SPEED USB DRIVER
After install windows SP2, I found the USB driver has not been updated. And my USB 2.0 divice can only function at a lower speed.

I followed the instructions from MS webpage, but the wizard couldn't find any relevant update for the hardware.

How to fix this problem?

Thanks in advance.

不太懂，你的USB接口本身是2.0的吗？UPDATE SP2前SUPPORT2.0？[@@@### (3-12 2:26, Long long ago)] [ 传统版 | sForum ][登录后回复]4楼
