[英]How do you get a composite USB Linux device with HID to wake up a suspended host?
The embedded system that I'm working with runs the 3.18 Linux kernel and when connected to a PC acts as a composite USB device with HIDBP functionality (allows you to connect a keyboard and mouse to it). 我正在使用的嵌入式系统运行3.18 Linux内核,并且在连接到PC时充当具有HIDBP功能的复合USB设备(允许您将键盘和鼠标连接到该设备)。 However, the problem I'm having is that a keyboard or mouse connected to it doesn't seem to wake up the host PC when it goes into full system suspend (a mouse connected directly to a PC can wake it up though).
但是,我遇到的问题是,与其连接的键盘或鼠标似乎没有在完全进入系统暂停状态时唤醒主机PC(但是,直接连接至PC的鼠标却可以唤醒它)。 I'm just wondering, is this a linux kernel bug and if so how would one go about fixing it?
我只是想知道,这是一个Linux内核错误吗?如果可以的话,该如何解决?
作为参考,从4.10.17版开始,主流总线内核中的USB HID复合设备尚未实现此功能
