A couple of US_FL_FIX_CAPACITY quirks for these two common USB/ATA bridges.
Hey Alex.
The first one (067b/2507) is already in Greg's tree - I submitted the patch on behalf of another report a few weeks ago.
Right; I caught that on the mailing list shortly after I created my own patch for FC3's current kernel.
The second one I'm a bit confused on. You say it's just an ATA Controller -- how can a controller present the wrong size?
The description is taken straight from the info in /proc/bus/usb/devices. It's the next bridge chipset up from the PL-2507 and adds (somewhat broken) Firewire support and uses two banks of 16KB of firmware to implement both USB and 1394 functions.
Until I created the patches, I could knock devices off the bus by doing things like:
dd if=/dev/sda of=foo.block bs=512 count=1 skip=<value near end of device>
It would dump a load of SCSI I/O errors when it tried to read the 'last' block then take the device offline. By googling for the model of disc I fitted inside the bridge-enclosure, I could see that the number of sectors it was reporting was one higher than that model reports when attached via a regular PATA connector.
