    It was a good suggestion so I turned off the firewall and then here's what I did:
    1) Added the folder containing adb/fastboot to the path and verified with command prompt that it worked. Then I removed all Acer drivers and rebooted
    2) Installed the usb driver called USB_Acer_1.0_A32H_A when extracted
    3) Then I plugged in the tablet and it did what is always does. It says "connected as a media device first and then says USB debugging enabled" or something along those lines. I'll see 2 icons in the status bar, one being the usb cable icon and the other is the small robot indicating that debug is on.
    4) Then I open my SimpleRoot folder and double-click on the simple.bat file which launches the command prompt and asks me to press any key to continue. At first is start the server because it wasn't running. Then nothing happened so after awhile I terminated the job.
    5) Disconnected the usb cable and then tried again This time it said checking for ADB driver and the device will reboot when driver is installed etc... After waiting a minute or 2 still nothing has happened so I opened a second cmd window and ran "fastboot devices" but that didn't give any ouput.... hmmm

    I guess I have 2 questions.
    Am I using the right USB driver (downloaded from Acer site and selected specifically the A200)?
    Is it normal that the tablet also get's recognized as a media device? I only have the option of connecting as media device or camera.

    EDIT: I managed to finally get the Acer drivers installed (the ones from simpleroot guide) but sadly it didn't make a difference. The simpleroot process still stops when checking the ADB driver so I'm still very much open to any suggestions!
    I also have an ubuntu 11.10 installed - so I wonder if running it from there will eliminate any windows "oddities". I not sure how to go about this though...

    Yes! Have moved on with Linux and now my tab is found when I run 'adb devices'. The problem is that 'fastboot devices' doesn't return any output. I see other having these problems but I have not found the right post to resolve my problems yet. A lot of people suggests this so I have created a file called '/etc/udev/rules.d/50-android.rules' containing the line:
    SUBSYSTEMS=="usb", ATTRS{idVendor}=="0502", ATTRS{idProduct}=="337c", MODE="0666", OWNER="ln" #ACER

    This was based on the output from lsusb which gave:
    Bus 002 Device 004: ID 0502:337c Acer, Inc.

    So a big step in the right direction but still not able to root it because of fastboot not working. If I run the simple_Linux script the tab reboots and the get's stuck in "Start in USB fastboot mode..." (can't remember exactly now.

    Do you have any idea about this? Did you have to mess around with UDEV rules at all..or?

    if adb works, your USB is recognized, so it's not the problem
    Are you sure your PATH is correct, to invoke the 'fastboot' binary usable in your Linux environment ?
    If you type :
    which fastboot
    You'll see which one is called
    That must be the one installed with SDK for Linux (not the one for Windows, located in directory unzipped from simpleroot archive)

    Wow! thanks for responding so fast...
    I believe those things you mention are in order though.

    ln@ln-laptop:~$ adb devices
    List of devices attached
    20207****** device

    ln@ln-laptop:~$ fastboot devices
    ln@ln-laptop:~$ type adb fastboot
    adb is hashed (/home/ln/android-sdk-linux/platform-tools/adb)
    fastboot is hashed (/home/ln/android-sdk-linux/platform-tools/fastboot)


    EDIT: Btw I deleted the .exe and .dll files from the simpleroot dir.


    EDIT: Success!!! It turned out that I had to run at least fastboot as root. So i just did sudo bash and executed the script and now I got root


    @Doume Merci beaucoup for pointing me in the right direction with linux and of course.... hail to the king (hbwelch)!

    Brizey did you figure anything out on this?

    Great!! it works with mine too;
    acer A200 bought in Germany;
    updatefile: acer_a200_av032.rv09rc08_av041.rv04rc02_emea_de.zi p ;
    image version: acer_av041_a200_rv04rc02_emea_de
    OS-host: windows 7 64 bits (I used the usb-drivers and tools from the original post)

    One small remark of a "rooting newby" (but an IT-oldie; 30+years-IT). Perhaps you could mention in step 4 or 5 that the tablet should be "powered up" after it has been connected.
    Apparently the tablet does not wake up by itself over the developer-usb-connection.

    The main reason for me to get the A200 rooted was to get rid of the CRAPWARE (Google+, Socialjogger etc.) that starts automaticly.
    I just found out that in ICS there is now standard an option to DISABLE/ENABLE system- and user-apps, so there is no need to root for that purpose anymore :-(
    But I think you can convince me of other benefits.
