RE: USB host Issue: scsi command abort

Hi,


By analyzing the packets exchanged on the USB bus, I noticed that sometimes the SETUP packet can have a length inferior to 8, by example 4. 
Did anybody ever notice this case ?

Best regards.

Hello,

I'm using a 2.6.18 kernel on a specific davinci platform and I tried to backport the last GIT MUSB driver. Unfortunately too much changes in the usb core stack. 
So I tried to compile the GIT kernel for EVM board, but I did not find any davinci defconfig.
Do you know where I can find it?
BR

Stephane.

They're not yet merged in any kernel I know of, outside
of (presumably) TI development trees.

Those two patches are candidates for 2.6.30 merge, pending
review and testing ... if they resolve this problem for you,
please tell us.  Confirmation that a patch works will help
that process.

The current plan is to integrate through mainline, and
maybe pre-merge patches queued for the next merge window
into the DaVinci (or OMAP) trees.  One way to look at
that is aiming to have the MM or -next staging trees
work for DaVinci (or OMAP) in the "normal" way.

We want to get away from having DaVinci-specific patches
languish in the DaVinci tree ... ditto the OMAP tree.

Specific to DaVinci there are a few patches that can't
yet queue to mainline, since they depend on support for new
SoC chips (notably DM355) which hasn't yet been queued for
mainline merge yet.


I recently signed off on ten low-risk patches that I hope
will be merged for 2.6.29-final ... and have about as
many (including the two Ajay noted) which would be
candidates for 2.6.30 (some are shoo-ins, others not).
