[Bug 54419] Re: usb change between 2.6.15-23 and 2.6.15-26 breaks working setup

[Akkana Peck]

To anyone still fighting this bug, I might have a clue. I just upgraded
to Feisty to see if the bug might be fixed. I plugged in an mp3 player
which had almost always triggered the "dead device" I/O errors in edgy,
then checked dmesg.

It didn't show up as sde as it should have -- but it gave a much more
helpful error message. Like a dufus I forgot to write down the exact
error message, and now I'm no longer seeing it, but it had something to
do with "not enough power." All my testing has been through unpowered
hubs. That was never a problem in the past, but maybe the kernel has
become more picky about that recently.

I found a power connector for my USB2 hub, plugged it in, and now the
device seems to be working under feisty. We'll see if it keeps working;
but anyone still having this problem, try using a powered hub or no hub
at all.
