hmm... good question!
i taked a look to the last git kernel_source and there is no support of procfs ( or i didn't found ) , it seems to support sysfs but it was added later for 2.6.21
Te is module parherameter usb_autosuspend_delay for usbcore you can try to set it to usb_autosuspend_delay=0 or to 60:
sudo gedit /etc/modprobe.d/options
options usbcore usb_autosuspend_delay=0
it can be this option working only with kernel 2.6.21
