USB MemoryStick reader and 2.5.66

[Stelian Pop]

Hi,

Is the usb storage driver supposed to work in the latest kernels, or
is there somewhere a big pile of scsi / usb-storage patches waiting
to be integrated and I shouldn't bother with that until then ?

This is with an internal USB Memory Stick reader on a Sony Vaio C1VE, 
which works just fine in 2.4, but in 2.5 it doesn't even gets 
recognized (hotplug ?). If I modprobe usb-storage manually the 
module loads just fine:
  Initializing USB Mass Storage driver...
  scsi0 : SCSI emulation for USB Mass Storage devices
    Vendor: Sony      Model: MSC-U01N          Rev: 1.00
    Type:   Direct-Access                      ANSI SCSI revision: 02

But then any attempt to mount it or even 'dd if=/dev/sda' hangs 
forever, the only messages I have in kernel logs are below.

Is someone interesting in a more complete bug report or should I
test something else ?

Thanks,

Stelian.
