Re: Sony vaio, UMASS0, etc

Yep, it's the umass one. And I should read more carefully.
Because now as I recall, the last time I snagged data off a 
stick I had put the stick in at boot.

I'll go run a quick test right now to eliminate doubt.
Sigh, yep I can read data off it after insertion at boot
and I do _not_ get insertion/extraction notification.

I'm chasing another USB error with that laptop right now too,
cause it isn't happy with with a flash disk that is ok 
under wintendo so since i'm getting jiggy with the 
usb sniffer and enabling driver diagnostic modes 
anyway.... I did some tracing.

BTW It sucks when your usb sniffer makes your memory
stick reader completely inoperable under Windows even 
after a reboot.  Sigh... fortunately a new version of usb-sniff 
off sourceforge seems to work better.

In case anyone cares I have a set of diagnostic traces
from a kernel compiled with full on gory usb and umass diagnostics
with the stick in at boot and with the stick out. In both cases I inserted 
and removed the stick which seemed to produce no traffic. I also 
have a win32 usb-sniff of stick access under windows if anyone 
wants but it  doesn't look too enlightening - as it contains no 
notification traffic that I see.

Neither under OBSD nor Windows does inserting or removing the 
memory stick produce a single peep over USB so whatever 
notification the stick device gives of inserts and ejects it doesn't
look like it goes over usb.  But windows somehow seems to know
(whether by IRQ or system message queue or whatever) that a stick 
has been inserted. Now maybe the win32 usb sniffer and the obsd 
kernel diagnostics do not pick up the messages, but I'm now looking
for some windows message queue sniffer so I can try to identify
just what the notification mechanism is... cause i want to be able
to switch memory sticks too!

So in any case it doesn't look like the fault lies in umass with mem
stick notifications on the VAIO.  However the fact that umass does 
not like my usb flash disk is another matter.  Just in case anyone 
cares about this I've also have win32 sniffs and obsd diagnostics 
from my flash disk. Email me if they are of any use to you.

But it doesn't sound like anyone else is really working on fixing either
of these issues and I am left to my own devices. It looks like fixing 
VAIO mem sticks isn't quite straightforward so I'm not holding my 
breath for it soon :(. The usb flash disk OTOH should be fixable 
more easily I hope.... If anyone else cares - mail me and 
I'll keep you posted if I make any progress.

sigh,
