Hello!!
We are using the AnywhereUSB/2.
On our Win Server 2008R2 we get randomly (weekly) BSOD caused by AwUsbSys64.sys (0x000000d1)
About 2 weeky above we updatet the Digi Driver to the lastest Version 3.51.49, because with the old driver we lost randomly the connection to the usb-device. So downgrade is no option 
I found the following post, but the driver of the doungle seems up to date (Only tested by WindowsDriversearch)
http://www.digi.com/support/forum/37628/bsod-0x100000d1-windows-xp-sp3-awusbsys-sys
In the Drivers-Readme I found the following info
If you put awusbsys and awvusbd under Driver
Verifier, it would cause a blue-screen because of the DV filter.
Fixed.
Can anybody help to find the problem and stop the BSOD?
Many thanks
Roland
