Comment 7 for bug 54273

ok, ok, I'm stupid, after write the comment, i search more info and find this:
http://www.linux-usb.org/FAQ.html#ts6

Q: Why doesn't USB work at all? I get "device not accepting address".
A: This can be one of several problems:

    * High speed devices sometimes have problems with cables used to connect them. They're more sensitive to signal quality issues than older usb 1.1 full or low speed devices. If the device works OK at full speed on the same system, after you "rmmod ehci-hcd", this is likely the problem you're seeing. There are a lot of things you can do to change signal quality........ [cont]

with this simple test "rmmod ehci-hcd" my pendrive USB work fine!!!

ok, good luck for all, and look the FAQ ;)
PD: sorry for my english (i'm spanish speaker)
