in the quirk file here:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/usb/core/quirks.c;hb=HEAD

you can find the newest blacklist of the known devices, there are some
scanners, modem, audio and blackberry.

You should test every usb-device you have.

to disable autosuspend you should do:
echo -1 > /sys/module/usbcore/parameters/autosuspend

and only _after_ this attach you device.

_only_ -1 disable autosuspend
