Definetly, the Toby Dickerson's suggest works on NFORCE2 chipsets (tested on 5 different mobo/distro, kernels 2.6.22, 2.6.25 and 2.6.27)
3 steps: 1.- Find all devices created yet with autosuspend # find /sys/ -name "autosuspend" /sys/devices/pci0000:00/0000:00:02.0/usb1/power/autosuspend /sys/devices/pci0000:00/0000:00:02.1/usb2/power/autosuspend /sys/devices/pci0000:00/0000:00:02.2/usb3/power/autosuspend /sys/devices/pci0000:00/0000:00:02.2/usb3/3-2/power/autosuspend /sys/module/usbcore/parameters/autosuspend and check his values # cat `find /sys/ -name "autosuspend"` 2 2 2 2 2 2.- Change all of this values to -1 # echo -1 > /sys/devices/pci0000:00/0000:00:02.0/usb1/power/autosuspend # echo -1 > /sys/devices/pci0000:00/0000:00:02.1/usb2/power/autosuspend # echo -1 > /sys/devices/pci0000:00/0000:00:02.2/usb3/power/autosuspend # echo -1 > /sys/devices/pci0000:00/0000:00:02.2/usb3/3-2/power/autosuspend # echo -1 > /sys/module/usbcore/parameters/autosuspend 3.- Test again all of those are -1 # cat `find /sys/ -name "autosuspend"` -1 -1 -1 -1 -1 All my usb sticks, HDD and printers works with 2.0 specs without any fault. I could better make a script, but this more understantable for fixing Someone can try this with another "bugged" chipset? All credits to Toby Dickerson!
