Important DLL files:
In wince, no matter which driver model is used, the physical performance of the driver is a DLL (dynamic link library file ).
The Dynamic Link Library has always been the basis of the Windows operating system, and wince is no exception. The core part of the DLL is three DLL files:
Kerner. dllRole: Manage memory, processes, and threads
Filesys. dllMan

In Linux, option. c is the driver for 3G modem. You can modify it to support most of the 3G usb modem.

* Power_services lists all services that are stopped when the power is switched to battery. (These services will be started again when the notebook is re-connected to the AC power supply .) By default, this list is very short, so you should add services including crond, autofs, cups, PCMCIA, and syslog To this list.

In this case, you can disable the uncommon devices such as the PCMCIA card, modem, infrared device, printer port (LPT1), or serial port (COM1) in the Device Manager, double-click the device you want to disable. In the Properties dialog box, select "do not use this device (disable)" on the "General" tab )".

When you press the button, a daemon will read/proc/ACPI/event, and execute the actions defined by the user on these events, such as shutting down the system. You can select either of them based on your needs.Part 7: delete all items except the followingBus options

IfYou're holding this book, you may be asking yourself: Why "yet another"Linux Device Driver book? Aren't there already a bunch of them?The answer is: This book is a quantum leap ahead of the others.First,It is up-to-date, covering recent 2.6 kernels. Second, and moreImportant, this book is thorough.

the operating current is between 500mA and ~ 1000mA, if the power supply is only through the USB interface, when there is no other USB device in the system, it can still be barely used, but if the voltage is unstable, the problem of insufficient power supply may occur at any time. Especially when using a mobile hard drive that supports USB 2.0, the situation is the most serious. In addition, if your laptop is powered by a battery, the USB interface will allocate less power.
