Substitute Win7 USB drivers for ADB mode Under Mac OSX there is no need for a USB driver for ADB mode.  Under windows, apparently, there is.

I'd like to be able to adb shell to my android tablet from my Win7 PC.

This table gives a list of where to get USB drivers for Windows for different OEMs.  My Android Advent Amico tablet's manufacturer isn't listed in the list.  Is there a list of what can substitute for what somewhere?  How, in general, can one determine which one(s) would be best to try? 

EDIT:
The tablet came with a utility called 'Advent Transfer Companion' for use in mass storage mode.  I've uploaded and installed that from the tablet, but it appears to be no more than a pretty way to write files to the tablet from PC - i.e. mass storage mode only, and no USB driver installed.
This says you should be able to use the "google drivers" after some minor tweaking. If your device came with any software for your PC, it will have the "official" drivers though, and I recommend using them.


  
  You must have Android SDK installed before you can proceed. If
  you don’t have it already, proceed to
  our guide on what is ADB and how to
  install it. Make sure you download the
  Google USB Driver Package as well.
  Open the google-usb_driver folder that you will find inside your Android
  SDK folder.
  Open the android_winusb.inf file in notepad or any text editor to edit
  it.
  Add these lines under [Google.NTx86] or [Google.NTamd64]
  depending on whether you are using 32
  bit or 64 bit Windows. If unsure, it
  is safe to add these under both these
  sections.
  
  
  
    ;NVIDIA Tegra
    %SingleAdbInterface% = USB_Install, USB\VID_0955&amp;PID_7000
    %CompositeAdbInterface% = USB_Install, USB\VID_0955&amp;PID_7100&amp;MI_01
  
  
  Don’t edit or replace any other
  text that is already there; just add
  these new lines and save the file.
  
  
  Open a command prompt window and enter this command:
  
  
  
    echo 0x955 >> "%USERPROFILE%.android\adb_usb.ini"
  


You will also have to enable USB Debugging in Settings -> Applications -> Development.

edit I would try this first:

This site has the "official" drivers for the tablet. You will still have to enable USB debugging, as I mentioned above.
