Like I said, neither are running unless I explicitly start them. I am just getting familiar with Linux, so it could take me some time to figure out, and I am not sure how that would ultimately help in the Windows 7 environment.ĭo you know of any issues when VM’s are present? I originally tried using Microsoft’s VM, but found some short comings and abandoned it for Oracle. Something I have not tried is bringing up the VM and seeing if I can use the COM port under Linux. Short of uninstalling the VM software (which I really don’t want to do) I am not sure what to try next. I double checked and the serial ports on the VM are disabled and the VM software is not started or running unless I explicitly do it, so I don’t really think it is the culprit, but it’s all I can think of right now. One thing that I even remotely suspect is that I loaded Oracle’s VM VirtualBox software and installed a Linux environment. If I had had this machine for some time I might suspect I downloaded something some time that is causing the problem, but it is only a few weeks old and I have not had too much of a chance to crap it up yet. I tend to agree with you that this is something simple that is just eluding us.

Tried procexp and nothing showed up in the search box for ProlificSerial.
