Speaking of control timeouts, I know someone with a similar problem. Check this out:

[repeating -71s and descriptor dumps from this point on] I thought at first that it's something that ub does. But apparently Glenn sees it with usb-storage as well. I cannot tell if this is the same thing, but it looks like a case of interference between the storage device and someone who's reading descriptors (udev in this case). -- Pete ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
