[linux-usb-devel] USB mass storage stopped working 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 have submitted a patch to the SCSI people, but haven't heard back from
them about it. It applies to 2.6.0; maybe it will fix your problem.
Please try it out and let us know what happens.
