Hi I have a 2.0 hub, and 2 2.0 cards (ALi OHCI and VIA UHCI) in 2 PCs. A high-speed memory stick works directly without a hub ok in both cards, works in the hub connected to VIA, but produces only errors in the hub connected to ALi. The complete USB log with verbose usb-storage debugging attached. This configuration (ALi + hub) doesn't work reliably with other 1.1 devices either. It did work before in this computer, but I am not sure anymore, if it was before I swapped the ALi and VIA cards or after... I think, it did work after - i.e. in the present configuration. Now it doesn't work with 2.4 kernels either. Tried with and without external power supply to the hub. Attached also lspci -v and /proc/bus/usb/devices.
Can it be the hub dying in such a strange way? When plugged in into a 1.1 port it does work too. Thanks Guennadi --- Guennadi Liakhovetski
