Hi, I need some help testing out my USB powersave implementation. There are now multiple levels of USB power save: 1) Turn off USB controller schedules when there are no transactions (1-4 seconds, not tuneable) 2) Suspend actual USB device (30 seconds, tuneable) Powersave is enabled by default. Tuneables: ========== How to set power save delay in seconds: sysctl hw.usb2.power_timeout=10 How to disable power save for the given USB device: usbconfig -u xxx -a yyy power_on How to enable power save for the given USB device: usbconfig -u xxx -a yyy power_save Known to work: ============== EHCI+UHCI OHCI - not tested yet How to install on FreeBSD -current (8.x) ======================================== svn --username anonsvn --password anonsvn \ checkout svn://svn.turbocat.net/i4b cd i4b/trunk/i4b/src/sys/dev cp -r usb2 /sys/dev/ make -C /sys/modules/usb2 clean all install --HPSReceived on Sun Dec 21 2008 - 14:54:24 UTC
