USB Mass storage problem in 2.6

I installed the 2.6 kernel to test it and I have some problems with the USB
mass storage driver: my external HD enclousure doesn't work anymore (the
device works perfectly with the 2.4.21 version).
My computer is an Acer TravelMate 521TE with an ALI USB 1.1 controller, the
device is an USB2 2.5" HD enclousure.
When I plug it the kernel detects it, but it gives a lots of errors and I
can't access the drive content.
I've tested it with the 2.6.0-test2 kernel version, attached there are the
lsusb output (from 2.4.21) for the device and the kernel log (compiled with
usb mass storage debug enabled).
I'm not subscribed to the list, please CC me any answer/comment.
Thank you in advance.
