Ticklish Techs

When I get a new laptop that always triggers a little cascade in my home network. I have three machines: An older laptop serves as a server, a quadcore desktop pc provides gaming power and the a newer laptop accompanies me wherever I go.

Some day ago I replaced the old server laptop (with WinXP) by a newer one, now running Win7.  My printer (Brother DCP-120C) is a little aged now and it’s not a network printer. So I attached it to the server (via USB) and thus it’s accessible in the entire network.

Attaching the printer to Win7 worked flawlessly. Importing the printer (which involves copying the drivers) to another Win7-machine was not a problem either.

But my quadcore still runs WinXP and wouldn’t accept the drivers from the Win7-server. Instead a dialog asks me to provide the appropriate driver manually.

Okay, so I downloaded the latest DCP-120C-drivers for WinXP, unzipped them and guided XP to the .inf-files. XP said: “No, I can’t see the right drivers.”

Unfortunately there is no way to force WinXP to use certain printer-drivers. So I spend ten minutes playing the old yes-no-game before I took a look at the .inf-file. I have never dealt with .inf-files a lot but I noticed this line:

"Brother DCP-120C Printer"   = BRDP120C.PPD, BrotherDCP-120C65FA

Hmm… okay… it is there. My Brother DCP-120C Printer. Fine. Why doesn’t WinXP recognize it? I found another .inf-file in the driver-package with these line:

"Brother DCP-120C USB Printer"   = BRDP120C.PPD…

Hmm… now the name is DCP-120C USB Printer. Do the funny name string make any dfference? I took a closer look at the printer device that was recognized by my server:

Okay, nice, there is no “Printer” in the name… can it be… well… I copied the line in the .inf-file and replaced “Printer” by “USB”:

"Brother DCP-120C Printer"   = BRDP120C.PPD, BrotherDCP-120C65FA
"Brother DCP-120C USB"   = BRDP120C.PPD, BrotherDCP-120C65FA

Bingo! That did the trick.

When accessing printers installed on other network computers, the printer drivers really seem to be recognized by their name. That hurts a bit, but knowing it may help solving driver problem from time to time.

I am a great fan of Acronis True Image. I am using it for a long time and it has saved my skin more than once. So I was glad to hear that the new version (True Image 2010) was designed to work with Win 7. And so it did.

Last week I got a new laptop and today I tried to backup my fresh installation ov Win7/64. Each time True Image caused my entire system to freeze after five seconds of backing up. No reaction at all, the only way out way a hard button-press reset. I tried different options without results. (Which made me panic, because on what else can you rely when not on your backup tool?) –

Fortunately I found the solution here.

There is a new driver for hdd-image snapshots. Installed it, True Image 2010 works again.

Phew!

My Lenovo X200 notebook comes with an integrated webcam and I’m using it pretty often for Skype calls etc. But some time ago it stopped working. After reinstalling drivers, taking to the Lenovo support hotline, installing exactly the driver I was told to it was still broken. Yesterday a Lenovo technician cam to replace the camera (I’m so glad to have on-site support and do not need to send the notebook in), but in the end the new webcam behaves exactly as the first one – just not working.

So I started to debug the problem by myself and figured the following out. Maybe this is just an issue on my machine with my other software installed but maybe this is helpful for someone else.

The driver from the Lenovo webpage is build by the camera vendor Ricoh. That driver package just does not work on my Windows 7 64bit machine. The out-of-the-box Windows 7 driver works just fine!

Find the Camera device in Device Manager

On the properties sheet choose Update driver

Then “Browse my computer for driver software” and  “Let me pick from a list of device drivers on my computer”

On my machine it only shows up one compatible “USB Video Device” – just use that driver:

If Windows does not find this single one you can select it from the larger list by unchecking “Show compatible hardware” and choosing “Microsoft” / “USB Video Device”:

For some reason it does not always work the moment I installed the new driver and I had to reboot the machine. After installing the driver the device in device manager is called “USB Video Device” but after the reboot it is for some reason renamed to “Integrated Camera” but still using the Windows driver (that is the important part, you can check it in the properties sheet from within device manager). From now on it was working fine.

After some time Windows suddenly replaced this driver with the Ricoh one and the camera was broken again. To prevent Windows from doing so I uninstalled the driver package from “Programs and Features” in Control Panel.

I’m using a Lenovo laptop and I’m a big fan of the Trackpoint mouse replacement. That is this small red thing in the middle of the keyboard some notebooks are equipped with instead of a touchpad. In fact my notebook does not even has a touchpad.

You can use the Trackpoint for scrolling like a mouse wheel when pressing the middle button and moving the Trackpoint up or down. Everybody using it will know what I’m talking about, anybody else does not need to read to the end.

But in some applications the scrolling does not work at all what is very annoying. I had the most trouble with Thunderbird and iTunes – just no scrolling.

And here is a fix for that issue. There is a file (C:\Program Files\Lenovo\ TrackPoint\tp4table.dat) on your machine when you have installed the Trackpoint software from Lenovo. Just edit that file and add some additional rows for the application with broken scrolling.

; Apple ITunes
*,*,itunes.exe,*,*,*,WheelStd,0,9

; Mozilla Thunderbird
*,*,thunderbird.exe,*,*,*,WheelStd,0,9

Remember to open the file with an editor as Administrator otherwise it would not work. I had to reboot my machine after that change. I just tested this change on a Windows 7 64 bit machine but it should work on 32 bit or other versions of Windows as well. Maybe the same fix applies also to non-Lenovo notebooks but I cannot tell. If someone out there tested it, please comment.
