g_mass_storage issues with 3.4.79+

[FW72]

Hi all!

I'm currently trying to use the g_mass_storage on a linux-sunxi 3.4.79+ kernel (A10-Olinuxino-lime board connected to Win7 host)
without success.

So far I learned that USB device mode might be (or is?) broken in current kernel - at least on Allwinner SOCs but maybe
my information is outdated?

I also tried to debug with an USB trace but so far I've only noticed that communications stops tight after negotiation phase
after Win7 driver got the serial number from the mass storage gadget.

Maybe someone more knowledgeable can shed some light on this issue or is there just some problem I've overseen to
make that work? (Hopefully)!

Thanks alot!

Frank

Did you have g_mass_storage working yet?

I have it working on my Olimex A20 board following below link, but with some issues.

My issue is:
1) If I connect my device to Ubuntu PC first, then do the "modprobe g_mass_storage...", then all works fine.
2) if I do "modprobe" first, then connect my device to Ubuntu PC, USB Mass Storage does not work.
