Anyway I will try buy for 1 euro external usb power supply > for my probe :) That's probably the easiest and most reliable way :) In the meantime, you could always check whether your USB ports are set to automatic power management: [davidp at columbia:~]$ cat /sys/bus/usb/devices/usb*/power/level auto auto If you get "auto", you could try forcing them to stay on - e.g. as root: echo on > /sys/bus/usb/devices/usb1/power/level Worth a try at least, if you're interested. Of course, you'd need to figure out which "usb$n" to use, depending on which port it's connected to - or just set them all to on: for file in /sys/bus/usb/devices/usb*/power/level; \ do echo "on" > $file; done Whether the above will actually make a difference, I don't know, but could be worth a try if you're curious. If you do, report back whether it helped, so everyone knows if that's a potential fix for anyone else who experiences the same problem :) -- David Precious ("bigpresh") <davidp at preshweb.co.uk> http://www.preshweb.co.uk/ www.preshweb.co.uk/twitter www.preshweb.co.uk/linkedin www.preshweb.co.uk/facebook www.preshweb.co.uk/cpan www.preshweb.co.uk/github
