Hi Peter,
Ok, this is a first step, it confirms the behavior of libusb interrupts
reads with darwin / MAC OS X, and that it does not handle timeouts.
In fact, the small change brought here (using a bulk read instead of
interrupt) leads to disabling the scan button features, as button events
are

Have taken a look at the libusb/darwin.c code, and as far as I can see,
usb _interrupt_ read sequences do not support a timeout. Timeouts are
only used for normal read or write operations.
Now I understand the meaning of the last message that appears in your
logs:
"USB pipe is an interrupt pipe. T

I am limited by my ISP to 20 MB of web space. I can put the old logs
back up, but that means having to take down the most recent ones.

Hi,
Yes, We can try to change the USB timeout used in the usb read/write
statements.
It is currently set to 1s, a default standard value that probably never
got tuned.
I can change it to 10s at least for Peter to give a try.
Will look at this and propose a test file to Peter.

hi Peter
finally some good news then! This proves that the backend basically
works on the Mac as well. I an only suprised to see that I had to
increase timeouts from the 10 seconds I used after Raoul had problems on
his mp620.
It would be good to see the logfiles of the failing attempts again. I
w
FYI- most other backends seem to have usb timeouts on the order of 30
seconds, unless it is a command that routinely fails, in which case it
is often set quite short.

On my OS X 10.5 iMac, I re-installed Xcode 3.1. I downloaded the
nightly CVS tree snapshot

So, I disconnected the USB cable and connected the MX850 to my D-Link
switch.
Then, from the 10.5 iMac (which currently has gettext 0.17, libusb
