Hasn't fixed my problem, but at least it gives me some information. Before unplug-replug: # ./hub.pl -l -d /proc/bus/usb/001/001 HUB Status: Local power supply good No over-current condition currently exists Number of Ports: 2 Ganged port power switching Port 1 Status: PORT_CONNECTION : 0 PORT_ENABLE : 0 PORT_SUSPEND : 0 PORT_OVER_CURRENT : 0 PORT_RESET : 0 PORT_POWER : 1 PORT_LOW_SPEED : 0 Port 2 Status: PORT_CONNECTION : 1 PORT_ENABLE : 1 PORT_SUSPEND : 0 PORT_OVER_CURRENT : 0 PORT_RESET : 0 PORT_POWER : 1 PORT_LOW_SPEED : 0 # After unplug-replug: # ./hub.pl -l -d /proc/bus/usb/001/001 HUB Status: Local power supply good No over-current condition currently exists Number of Ports: 2 Ganged port power switching Port 1 Status: PORT_CONNECTION : 1 PORT_ENABLE : 1 PORT_SUSPEND : 0 PORT_OVER_CURRENT : 0 PORT_RESET : 0 PORT_POWER : 1 PORT_LOW_SPEED : 1 Port 2 Status: PORT_CONNECTION : 1 PORT_ENABLE : 1 PORT_SUSPEND : 0 PORT_OVER_CURRENT : 0 PORT_RESET : 0 PORT_POWER : 1 PORT_LOW_SPEED : 0 # I saw that Port 2 seems to be up-and-running right from the start and tried plugging the UPS into it, but it didn't seem to help. And using the -c <portnum> option to reset port power didn't seem to do anything. I also tried modifying the function called by -c so that it would unset/reset "PORT_LOW_SPEED" instead of "PORT_POWER". That didn't do anything either. I'm not sure I'm using the -c option correctly, though; no matter what junk I feed to it, it always says "Clear Port Power ok...Set Port Power ok". Typical: # ./hub.pl -v -c 0 -d /proc/bus/usb/001/001 001 001 Scanning bus name = 001 Bus: 001 001 Device: 002 001 Device: 001 001 Found device idVendor 0x0000, idProduct 0x0000, Class 9 A total of 1 hubs was found. Clear Port Power ok Set Port Power ok # I've tried "-c 1", "-c 2", "-c 001", "-c 001/001", etc, etc, but nothin' seems to do nuthin'. So... I dunno. > Not sure about the root cause of the problem, though. What > kind of USB host controller is it? (UHCI, OHCI; also, which > driver?) UHCI, hidups driver.
