I can answer my own question – it’s a windows firewall thing. If I open our Windows application with the Gumstix connected to USB hub #3 I get asked for connection confirmation, then everything is OK for more direct access via a browser. I fired the app up so many months ago I had forgotten. Windows hadn’t.

Subject: [Gumstix-users] magic usb port
I have inherited an application which runs Lighttpd Web Server on a Gumstix Overo WaterSTORM. If I plug the OTG USB into the left-hand socket of my (powered) StarTech USB hub everything is fine with the given IP address (192.168.1.1) I can connect & see files that I expect to see. Yet, if I plug the USB cable into any other socket (3 remaining sockets on StarTech hub, front or back sockets of Windows PC) I get:
The requested URL could not be retrieved
Connection to 192.168.1.1 failed.
The system returned: (61) Connection refused”
How is this possible?
Is it a USB enumeration issue? Or USB speed issue?
What do I need to do so I can connect on any USB port, not just my magic No. 1?
