你的制作依據是USB協會規范。可以參照UL2725、2835、20276等

大家好.

请问有谁知道USB协会的联系方式?

直接上USB协会网站www.usb.org ,国内如果要搞USB认证直接找台湾ETC,我去年刚搞过

USB2.0的电线结构和传输特性的标准是在USB2.0规范上的,但在USB2.0的规范上并没有规定符合那个安规,一般情况下我们是依UL规范做的,因为USB2,0的结构按UL758标准对号入座的话有2725,20276,20379等等很多,有的厂家还用2835,所以这个并没有定论,要看你客户的要求了.

USB2.0 的標準是要求TYPE CM（UL444) 的。 協會認証好象也接受2725。

补充一个：2547也可以

有USB协会认证的，就可以印USB字样；

没有认证的，多以2725的印字出现。
