Basically, I have 2 USB ports on my box: - on one there's a USB2 harddrive (running in USB1.1 compat mode; I did not compile ehci into the kernel because I was having kernel panic on boot) - on the other, there's an USB hub connected (with 3 devices connected to the hub) After some time (usually around 12 to 24h), the devices on the USB hub are not accessible anymore and I have to unplugg then replugg the hub power switch again for the devices to work. This does _not_ happen when I unplugg the USB harddrive (I unplugged it for like a week and had no problem). Note that _all_ my devices have a power switch. So my questions would be: - do you know where this problem could come from ? - do you have any idea how I could maybe send some data to the USB port to keep it alive ? Thanks in advance.
