Hi David,
unfortunately I had been sick as well being under pressure on a
different project.
Now my boss has promised me time from Monday next week to resolve the
issues.

I have been working on a usb kernel driver for the frontier designs "tranzport"
control surface. It's a pretty unique device - 20 character LCD, 7 lights, 21
buttons, and a shuttle wheel.
Anyway, as I have something that more or less works better than the current
ardour2 libusb driver...

It does pretty much what you said you saw -- it hints to the controller
driver that this URB doesn't need more than one pack

Hi,
here's autosuspend for storage devices. It was surprisingly easy.
I've tested it and I can play an mp3 and see how the stick wakes
up every few seconds. Comments?
To test this you'll likely have to turn off haldaemon. This still
needs a solution.
Alan, do I recall correctly that you have a mou

I'm using Cypress bulkloop.hex firmware on an fx2lp (CY7C68013A) with simple
host-side user-land code to transmit data to EP2 (out endpoint) and read the

Pardon the very long lines. This has been fixed now.
My usbmon shows the following:
--- (1) Test for 12 bytes TX/RX _without_ writing the extra 1 byte bulk
--- packet ---
(12 byte tx/rx: run program for first time)
eb13c640 4268765364 S Co:028:00 s 00 09 0001 0
eb13c640 4268765473 C Co
This is even more bizarre, the output below is from usbmon when I do two
12-byte writes/reads within the same program (in the previous example I
posted I did 2 12-byte writes/reads by calling my program twice).

No problem.
Greg, do you want an updated p
This patch (as853) cleans up the new USB blacklist code in several
ways:
Replace the STRING_FETCH quirk with STRING_FETCH_255,
meaning not to use a 255-byte query when retrieving
string descriptors. This is all that the problem-causing
HP scanners require.
Oliver:
This patch includes the various facilities we have been discussing. It
seems to work okay.
Obviously it isn't in final form. It needs to be cleaned up and broken
apart into several simpler patches. But you ought to be able to test it
easily enough. It needs to go on top of as853, p

Here is my concern. If the HID layer is fixed to support Digitizers
which means we would no longer need separate drivers, then how are
we(Digitizer manufacturers) supposed to get the digitizer input before
the X Mouse driver takes it? Please forgive my ignorance, but I'm still
learning.

I decided not to cram the ISO descriptors into the old line format,
primarily because my parser would still choke on ISO no matter what.
I added a new format '0u' in addition to the old one '0t'. So we have
a bit of a bloat, all structures grew somewhat, output lines grew too...
