强制驱动程序与设备匹配 [英] Forcing driver to device match

问题描述

我有一块USB硬件，我知道该驱动程序. 但是，供应商ID和产品ID与驱动程序中注册的VID，PID对不匹配. linux中是否有一种方法可以强制驱动程序与已知设备相关联，而该驱动程序不涉及内核模块重新编译以添加PID/VID对?

I have a piece of usb hardware, for which I know the driver. However, the vendor id and product id do not match the VID, PID pair registered in the driver. Is there a way in linux to force a driver to be associated with a known device, that do not involve kernel module recompilation to add a PID / VID pair ?

推荐答案

在sysfs树中查找模块.在这种情况下，

Find the module in the sysfs tree. In this case it was in

/sys/bus/usb-serial/drivers/cp2101

在此目录中，有一个new_id文件条目，可用于动态添加VID PID对，如下所示:

In this directory, there is a new_id file entry that can be used to dynamically add VID PID pair like this :

echo VID PID >new_id
