And yes, it works in another computer, at high speed. Just tested in an Athlon XP, nForce2 machine: 00:02.0 USB Controller [0c03]: nVidia Corporation nForce2 USB Controller [10de:0067] (rev a3) I've also got the same symptoms on the same Mac Pro/USB adapter combo with a totally different thumb drive. The drive is recognized and read initially, but a few seconds later, it becomes unresponsive, as do other devices (I'm tewting with keyboard and mouse) plugged into the same controller. Thanks a lot for your help; I know this is frustrating. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
