关于LPC1857的USB

[wushenyue]

你好：

我在使用1857USB_CDC的时候，使用的VCOM能在win10上使用连接，但是在win7上不行，是否需要win7的驱动进行支持

Hi

Do you use LPC1857 demo board or your own pcb? if demo board, which one?

Which demo code do you work with? Please let me know thus we can test.

I never heard win7 can't recognize USB CDC VCOM. I would suggest you test it on another win7 computer.

Have a nice day,
