Description
When I start a VM the first time, the VBoxSVC terminates due to end error. I used the debugger to track more details. It is this line:
1001F9F4 mov eax,dword ptr [edx] with EDX==0, EAY==7
I will store more lines into the file disasm.txt and attach it.
In older versions I had seen this sometimes. Gutt felling says it is related to USB.

I disabled the only USB filter in the settings of the VM. Now the error does not show up anymore. Filter: Name=Phone,VID=0681,PID=0022,Remote=no, rest empty If you need that phone for a day, then I can bring it to you.

Hmm, any chance to test the same device with VBox on a Linux host and provide a core dump? Or could you provide a minidump for that crash?

Hi Frank, I will try to get a mini dump. But I will need a few days (just came back from vacation). This is an outstanding bug since quite some time, it would be a big improvement to get it solved. I could even borrow you the phone for a day. BTW: With the USB analizer I saw a stalled descriptor transfer. But the retry was fine though. Let me know if it helps to see the USB traces. It is for the Ellisys 200. Their tool runs in view-only mode if you do not have the analizer connected.
In the past I saw similar effects with my Windows mobile phone and barcode scanners (no stalled transfers for sure).
Dissam, stack,threads etc.
