I have a similar issue as well, having recently purchased a ROM pack.  
I am only getting a chance to troubleshoot it this week. I'm figuring  
it's an issue on the Windows side. My XP actually blue screened after  
a time from this. I'm using a Keyspan HS19 USB adapter. The keyspan  
driver install had issues from the start. I'll let you know if I find  
anything, and I'll keep watching the list.
