It runs perfectly on WinXP. So, connectors should not be an issue. It might
be a problem with not-fully-standard things by SE, Also, I tried to play
with different FAT types (16/32). FAT16 seemd to be much faster, but also
not yet ideal.

After I upgraded the phone software yesterday and reformated flash using
native phone tools,  it helped:

da0: <Sony Eri Memory Stick 0000> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: Attempt to query device size failed: NOT READY, Medium not present
umass0: at uhub2 port 2 (addr 2) disconnected
### first try was not successful, but w/o any other errors in console

(da0:umass-sim0:0:0:0): lost device
(da0:umass-sim0:0:0:0): removing device entry
umass0: detached
### Reattached the device

umass0: Sony Ericsson Sony Ericsson K750, rev 2.00/0.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Sony Eri Memory Stick 0000> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 951MB (1947648 512 byte sectors: 64H 32S/T 951C)
### And yes, it's finally up and correctly sized

So, the only FBSD-related issue left is a duplicated entry in /dev listing.
Reboot helped, but that's not the way it should be. Could someone check the
possibilities to have duplicate entries in directory listing (at least under
/dev)?
