"old framework of adb in target" ===> means i don`t use the composite driver in target if the host is ubuntu.you know, before composite gadget driver, the adb is a single gadget driver(kernel 2.6.25). kernel 2.6.29 add a composite gadget driver, mass storage and adb are the functions of this composite gadget driver.
" Are you saying that the usb transfer seen when using windows is same as linux, except the 0 length packet ?"===> yse, in ubuntu, host will send 0 length packet after a packet which size is 4096 or the multiple of 64 and our usb protocol analyzer can catch this 0 length packet. In windows, our analyzer cannot catch this 0 length packet. But i have checked the usb_windows.c, it will send a 0 length packet.So i guess the usb driver in windows block this 0 length packet? 2009/8/28 Tejas <tejas.path...@gmail.com> > > I am assuming you meant 4096 bytes..
