This may be due to the fact that the devices are of the same model, or you enabled the auto-sharing option. If you feel this is not the case, you can send us screenshots of the faulty functioning to support@fabulatech.com
I am also having the BSOD problem on system reboot of a Dell PE1950 server with windows server 2008R2.
It does this even in safe mode! I have to rename the ftusb.sys and ftusbload.sys files to get the system working again (alltough this also means I have lost the USB attached mouse and keyboard and now have only access through RDP)
Could you send me the 4.4beta? Any ideas when 4.4 will be generally available?
It should be ready in a couple of weeks, our develpers are adding latest fixes to it.
Meanwhile, i'll send you 4.4. via email. There's no guarantee it's a remedy to this particular problem, so please leave your feedback once you test it.
