Hi Everyone,
I have some more information regarding this. Its seems the driver is
not able to create bulk end points. I added some debug prints in
f_adb.c and epautoconf.c Here is the output

It seems, it is not able to search and find the required "free"
endpoint. So how do I take this issue further? Is there any solution
for this?
There is a static matching on the pxa27xx driver usb and you have only two
bulk (in/out) so you can use gadget and no the storage.
One solution that give the possibilty to have more bulk point is to create
manually in the static table. I have tried this but I have some
problem of stability.
I have some patches to pxa27x_udc that get the Android composite
gadget driver working with f_adb, f_mass_storage, f_rndis, and
(probably, untested) f_acm, simultaneously. I've tested them on a
pxa320 (pinging over rndis while using adb shell and md5sum of a file
from a f_mass_storage device) but I think they'll work on other pxa3xx
and on pxa27x processors.
I'll try to get them pushed upstream soon, but it will probably take a
bit longer since I'll have to make a case for an additional controller
driver hook ep_autoconfig.
Can you send to us a preview of that. I have done a quite similar work
and the only problem
was plug/unplug on the 2.6.32 kernel
