It should run fine again if you use the usb-uhci module instead of uhci. I think something is broken in uhci.c since 2.4.10. Many users of the speedtouch usb modem wrote to our ML to report such a problem. All users were using uhci. I've done some basic tests and uhci was responsible of the slowndown. 2.4.11 solved the timeouts problems, but the slowdown has not been solved yet. -- Edouard Gomez http://perso.wanadoo.fr/ed.gomez - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
