Opensuse 13.1 Guest
I have set up 2 usb filters for USB to Serial converters(I have 2 different ones, so that i can always have them connect to the same ttyUSB port in linux)
In linux I have set them up with symbolic links to ttyS0 and ttyS1 and everything works perfectly.
Now for the issue, the system stays up and running no issues with sleep or crashes. But after some time, the usb devices just stop working, in linux (ls /dev/ or lsusb) they are still connected to the system.
As I am running a temperature monitoring on the guest, is can say that the serial ports worked from 23sep 15:30 until 24sep 17:48
When i reboot the VM everything works again.
In linux messages log I cannot find anything that would cause an issue, and I cannot find any message stating the usb devices have been disconnected.
In VBox.log i see nothing except for dhcp offering an Ip adress
In windows even manager i can find 1 message that occurs around the time the adapters stop working:

I am able to find id 3180 = svchost
Is this event the actual issue why the usb devices stop working, or should i look somewhere else ?
