This is something that has puzzled me for a while, since sometimes I see this behavior and other times I don't. I already know that individual USB devices can be uniquely identified, as demonstrated on my work computer where each time I plug in a different serial USB device it creates yet another Com port. I think I'm up to Com 77 after testing that many devices for work!

But you're saying that the specific USB connector port on the computer also has a unique identity? That can really hamper operations in some (many?) cases if so.

At the very least there should be means simply to detect the USB device and forge ahead regardless of which port it is plugged into.

Hello Bob, Do you get the error without the DMK URI? Also you need to use the same USB port that you used at install. If you move the URI to a different USB ports you will get errors.

After one week of satisfactory operation, my Allstar node (27890) has the following error:

"USB 4-1  usbfs:  27618  (asterisks) did not claim interface 3 before use"

Error code 1, then the computer reboots its self.  The five digit number changes, but the problem just keeps repeating.  The only USB device connected is the DMK URI (9080).

Cause of the problem?  How to fix the it?  Thanks in advance for any help.
