Re: Download Driver Console To Usb

[Donnell Simon]

Windows driver developers and testers can use DevCon to verify that a driver is installed and configured correctly, including the proper INF files, driver stack, driver files, and driver package. You can also use the DevCon commands (enable, disable, install, start, stop, and continue) in scripts to test the driver.

The DevCon source code is also available so that you can examine the methods that DevCon uses to retrieve and change setup and configuration data. DevCon illustrates the use of general setup functions, device installation functions, and PnP Configuration Manager functions. The source code for the Device Console (DevCon) Tool is available in the Windows driver samples repository on GitHub.

Console DriversThe Linux kernel has 2 general types of console drivers. The first type isassigned by the kernel to all the virtual consoles during the boot process.This type will be called 'system driver', and only one system driver is allowedto exist. The system driver is persistent and it can never be unloaded, thoughit may become inactive.

The second type has to be explicitly loaded and unloaded. This will be called'modular driver' by this document. Multiple modular drivers can coexist atany time with each driver sharing the console with other drivers includingthe system driver. However, modular drivers cannot take over the consolethat is currently occupied by another modular driver. (Exception: Drivers thatcall do_take_over_console() will succeed in the takeover regardless of the typeof driver occupying the consoles.) They can only take over the console that isoccupied by the system driver. In the same token, if the modular driver isreleased by the console, the system driver will take over.

If sysfs is enabled, the contents of /sys/class/vtconsole can beexamined. This shows the console backends currently registered by thesystem which are named vtcon where is an integer from 0 to 15.Thus:

When unbinding, the modular driver is detached first, and then the systemdriver takes over the consoles vacated by the driver. Binding, on the otherhand, will bind the driver to the consoles that are currently occupied by asystem driver.

How useful is this feature? This is very useful for console driverdevelopers. By unbinding the driver from the console layer, one can unload thedriver, make changes, recompile, reload and rebind the driver without any needfor rebooting the kernel. For regular users who may want to switch fromframebuffer console to VGA console and vice versa, this feature also makesthis possible. (NOTE NOTE NOTE: Please read fbcon.txt under Documentation/fbfor more details.)

All drivers, except system drivers, must call either do_register_con_driver()or do_take_over_console(). do_register_con_driver() will just add the driverto the console's internal list. It won't take over theconsole. do_take_over_console(), as it name implies, will also take over (orbind to) the console.

All resources allocated in con->con_startup() must be released when thedriver, which was previously bound, becomes unbound. The console layerdoes not have a complementary call to con->con_startup() so it's up to thedriver to check when it's legal to release these resources. Callingcon_is_bound() in con->con_deinit() will help. If the call returnedfalse(), then it's safe to release the resources. This balance has to beensured because con->con_startup() can be called again when a request torebind the driver to the console arrives.

do_unregister_con_driver() can also be called on conditions which make itimpossible for the driver to service console requests. This can happenwith the framebuffer console that suddenly lost all of its drivers.

I have a simple Python script which uses selenium and webdriver to open up Facebook in a Chrome window and log in automatically. When I run it, the Chromedriver console window opens up and stays open even after the entire program has finished execution, until I close it myself.

Is there a way to hide this console window? I have tried keeping a ".pyw" extension for my script, but that doesn't help since it's not the script's console window but the Chromedriver subprocess' console window that I wish to hide.

To hide the webdriver console window, I had to edit the Lib\site-packages\selenium\webdriver\common\services.py in my case but I was using PhantomJS. PhantomJS imports and uses this file to start its process. Basically, I added the following creation flag to the Start method:

My question now- is there a way I can revert to the Standard AHCI Driver? Possibly using a recovery console? I want to avoid re-installing Windows, which is the only way I can see to fix this problem now.

Type pnputil -e to show a list of installed drivers.
You may want to use pnputil -e more so the list is output one screen at a time.
After you've located the driver in the list, note the inf file shown for the driver (e.g., oem00.inf).
Type pnputil -d oem00.inf to delete the driver.
You may need to use pnputil -f -d oem00.inf to force deletion.

Aruba hardware devices that use a USB console or custom proprietary console cable require a console driver to enable the USB console cable on a laptop (if they are not already supported on the laptops). This document describes where you can download console drivers for your USB device. You can download a PDF version of this document here.

I was recently reminded of one of the things I didn't like about nVidia cards & Linux. I've installed 3-4 of them over the years in different machines (different cards, driver versions), and every one of them did the same thing to me:

After installing the proprietary driver (the open-source is fine), the virtual consoles (1-6) no longer work. (The problem was mentioned in this question, but a permanent solution was not the asker's priority.)
