Http://linuxidc.com: 81/Linux/2011-03/33430. htm I tried to follow these steps yesterday. But there are two problems1: The arm card distribution board uses busybox, and some applications (such as dhcpcd) are compiled in the Android system. My compiledUsb_modeswitch cannot run2: After a

the implementation process of the USB driver model and the sample program in Windows CE, based on the sample code, straighten out the development idea of the driver for the USB device. Similarly, the readers in this article are expected to be the readers and those who are r

devices in the Linux kernelFor the connection on the specific bus external devices have a struct device corresponding, such as platform equipment has platform_device corresponding to it, which platform_device structure is as follows: struct Platform_device { const char * name; Device name to match the name of the driver and, if successful, into the driven probe f

Setting up a real-world development environment requires the following steps:1. Declare the application to be debug in the application's manifest file;2. Open the application debugging support;For apps created through Eclipse, you can omit step 2, because debugging support for your app automatically opens when the Eclipse IDE launches the app.Note: In the application development process, to manually enable debugging support in the manifest file, it is best to turn off debugging support before th
