Old issue with Sony Ericsson W800i reporting wrong Memory Stick capacity
seems to be solved - with new firmware R1AA007 it reports something closer
to 512 MB:

I want to mount the Imation pen drive. Because I am using /dev/sda1 for
hard disk, which /dev/ file I can use for mouting?
I have one more Red Hat Linux machine. On that machine, I am able to
mount using /dev/sda1. Please suggest me.

Just to remind kind reader, I had issues with digital camera spontanneously disconecting
itself after some 80 MB were read from MemoryStick card.
The device was plugged into front panel USB connector, which acted as "extender" cable.
When plugged to case back USB ports (connected directly to ma
I don't know the cause, but it's not the result of a change in the
usb-storage or SCSI code. It could well be a change in FAT32. Go ahead
and file a bug report, and direct it to the filesystem people. They
should be able to explain everything.
Done, details here:

You could experiment with not using -o sync. Under 2.6.13-rc2 or later it
may turn out to be just as reliable.
Alan, I've run some preliminary 2.6.13-rc2 tests, but it seems that key factor
is really -o sync.
With -o sync I'm still getting cca 150 kb/s write speed, whereas without
-o sync I wa
I don't understand that at all. If you rebuild the driver with debugging
turned off, does the throughput decrease again? (That is, was this caused
by the rebuild itself or by the debugging code?)
2.6.12 usb-storage with debugging writes 1.4 MB/s, 2.6.12 non-debugging
usb-storage makes only cc
with -o sync or something similar. You might find it interesting to try
doing the exact same write transfer under both 2.6.11 and 2.6.12, with
usb-storage debugging turned on for both systems, and then compare the
debugging logs. If the timings are so drastically different then I would
expect

The striking thing about your log is that all the commands are WRITEs and
they are all relatively short. Is the speed for reading better than the
speed for writing?
Yes, it seems like you are pretty close - transfer rate differs for writing
only! For USB 2.0 device read is cca 16,7 MB/s for bo
This is pretty strange - with 2.6.12.1 I'm getting write trasfer rates 58 kB/s with USB
1.1 device and 160 kB/s with USB 2.0 device (as opposed to 225 kB/s and 4 MB/s
respectively with 2.6.11).
It doesn't seem to be hardware related, as this speed drop is seen both on PCI USB 2.0 NEC

There's no obvious reason for this. Unless you are encountering some sort
of error during your transfers, causing some of the operations to be
retried? If there were any errors, they would should up in the log when
you turn on CONFIG_USB_STORAGE_DEBUG.
No errors at all when running "normal"
