The answer to both questions is No. But you can help start the process
off by gathering some data.
In the source file for g_file_storage, drivers/usb/gadget/file_storage.c,
around line 220 you'll see this:
#undef DEBUG
#undef VERBOSE
#undef DUMP_MSGS
Change those to #define instead of #undef and rebuild the driver. After
trying to connect to the Vista host, run dmesg to see the debugging log
and post the output here. Maybe it will tell us what's going wrong.
Does Vista work okay with regular USB flash drives?
