Hi all ... I am doing this in my project Step 1 : I acquire some data on beagle board on angstrom linux and send to SD Card by mounting it on Beagle Board. Now I unmount the card from beagle board andÂuse g_file_storage gadget driver to mount the sd card on host. Step2 : Now after Host acquires the data from the sd card, Then i want to remove driver & mount it on Beagleboard and use storage again on B.Board. But How will the beagle board know when to again unmount the gadget driver and again mount sd card on beagle board. How does BB capture the eject event ? Is there some concept of composite driver in linux where mass storage class can be used along side say uart interface ...........using the same physical usb communication path to send commands from host to beagle board which can aid the above operation. Please help me if I am thinking wrong. Please suggest. ============================== i want to use usb MSC for showing storage at HOST ....and use usb serial for sending some commands from host at that time ...like eject event ================================================== i have these alternatives ... 1)use usb port to send data from BB to HOST and another uart port for sending eject usb --event to BB -- but thats last i would want to do ..... 2)using usb-multi driver ...if i can do that .... i have googled and found http://www.mjmwired.net/kernel/Documentation/usb/gadget_multi.txt ..will it be useful in my situation ? is it feasible to fulfil my requirement with this driver ? please help. -- Thanks & Regards Nidhi Mittal Hada http://nidhi-searchingmyself.blogspot.com/ -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
