VMWare Workstation: high-speed USB 2.0 support vm

8 11 2008

Since couple days I am running Windows XP x64 and I wanted to scan some documents with my old Canon Lide scanner which is connected by USB cable on the host. Drivers are not supported in Windows XP x64 and therefore I am using a Windows XP 32bit virtual machine.

After connecting the scanner in Removable Devices I get the message below: 

  • Please upgrade your virtual machine to enable high-speed USB 2.0 support for the device “Canon CanoScan”. An attempt will be made to connect this device to the best available host controller. This may result in an undefined behavior for this deviceVMWare-Workstation-Warning-USB-2.
I did some research on the Internet and found some interesting posts. It looks like the virtual machine has an older version which does not support USB 2.0.  I opened the vmx file with Notepad++and checked the virtualHW.version which was set to 4; the virtual machine has VMWare Workstation 4 hardware compatibility version set.
VMWare-Workstation-hwversion
There are two ways to change the version:
  • Shutdown the virtual machine; click VM in the menu and choose “Upgrade or Change version”; follow the wizard and choose VMWare Workstation 6/6.5
  • Open the vmx file in Notepad and change virtualHW.version = “6.0″ and add ehci.present = “TRUE” to the configuration.
Getting done is how the virtualization at least helps me here. Scanner is now working.

Webdesign: CSS Min-Height for Internet Explorer

7 11 2008

This morning I started creating and testing a new CSS website template for one of my pending projects. After creating the CSS stylesheet and basic HTML page with DIV’s my content container and footer are not being displayed as they should. For the content div container I assigned CSS property “min-height=400px;”. Using of min height of 400px the website will have nice overview instead depending on the content I enter in the container. The result:

The screenshot was made in Internet Explorer and I checked all my html and css code and everything looks fine. I opened Firefox and opened same URL and the page was displayed as it should be 400px for the content container ;). I am new in the web devolvement and trying to get the basics but this is one example when working with different browsers. Internet Explorer ignores “min-height” and always assign it 8em if the container doesn’t contain data. To fix this problem you will need to define addition CSS declaration for the container.

 

  • div#content {
       min-height: 400px;
    }
  • * html div#content {
    height: 400px;
    }

or use another solution

  • div#content {
       min-height: 400px;
       height:auto !important!;
       height:400px;

    }

Wow this fixed my first problem.

ImgBurn is a free tool that enables you to burn CD/DVD images with ease. All the latest drives are supported (including booktype / bitsetting on many of the major ones). Advanced functionality can be found in the ImgBurn context menus.

ImgBurn supports a wide range of image file formats - including BIN, CUE, DI, DVD, GI, IMG, ISO, MDS, NRG and PDI.
ImgBurn supports all the Windows OS’s - Windows 95, 98, Me, NT4, 2000, XP, 2003, Vista and 2008 (including all the 64-bit versions). If you use Wine, it should also run on Linux and other x86-based Unixes.

If you never heard of this tool than now you should download and install it ;). I am using this tool to burn cd-roms from my Windows Server 2008 Hyver-V whitebox and it works smoothly. Beside all burning features one other which comes handy is to grab a folder and create a ISO file; than mount the ISO file with Hyper-V or ESX virtual machines. I used this feature many times when working in the test and production environments.
