Hi Paul, As I know that we didn't have Web API for this purpose now but just had some similar but not accurate ones.
Ex: 1. USB Mass Storage. (Need to get result by enabling it) 2. Battery Charging. (Not sure that charging is came from PC or Wall Charger) (Once device's loaded current is bigger then charging current, it becomes not thing) Also we are collecting the use case for proposing the new Web API for detecting such kind of things. What we got are 1. As a user, I want to choose the preferred USB functionality when USB is plugged in. (ex: Mass Storage / MTP / Charging Only) 2. As a user, I want to get a pop up message for notifying PC didn't provide USB tethering function. 3. As a user, I want to know charger is connected or not no matter charging current can be enough for device's loaded current or not. May I know your use case? Thanks, Sincerely yours. ----- 原始郵件 ----- 寄件者: "Paul Tsvika" <mozloverin...@gmail.com> 收件者: dev-b2g@lists.mozilla.org 寄件備份: 2013 12 月 10 星期二 下午 2:56:39 主旨: Re: [b2g] FxOS how it detects the usb connection to PC? Hi Jan, Your approach will only work when enabling USB storage. My intention is to detect pc usb connection event without enabling USB storage. Do you have any idea about this? _______________________________________________ dev-b2g mailing list dev-b2g@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-b2g _______________________________________________ dev-b2g mailing list dev-b2g@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-b2g
