Hi, I have a NEC LCD1525M monitor, which comes with a 4 port USB hub to which my keyboard and mouse are attached. It works fine unless I leave it overnight; at which point the machine no longer responds to the mouse and keyboard. Unplugging and replugging the keyboard has no effect, but unplugging and replugging in the cable between the system and the hub makes everything work again. Does anybody have any idea what could be causing this? I'm guessing the hub is going into some kind of power saving mode because of inactivity.
The relevant lines from /proc/bus/usb (at least if I'm parsing it correctly): T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 22 Spd=12 MxCh= 4 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0409 ProdID=55ab Rev= 2.00 C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=100mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.) MxPS= 1 Ivl=255ms The machine is a 450MHz G4 macintosh, running Yellow Dog Linux 2.0. It is currently using Linux 2.4.13-pre3 derived kernel rsync'ed Tuesday morning from rsync.penguinppc.org::linux-2.4-benh. Thanks. P.S. The /proc/bus/usb/devices output for the motherboard USB port is: T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc=132/900 us (15%), #Int= 4, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 0.00 S: Product=USB OHCI Root Hub S: SerialNumber=f202b000 C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)
