Hi victor,
Regarding UMS support:
The last version posted at u-boot ML can be found at [**]:
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/113004/match=ums
I've go through your fixes for file_storage.c.
Please find appended diff file [*] for changes which I was able to
apply on the original file_storage.c file (taken from [**]).
I've attached output from Host dmesg and target's console (output.txt)
It seems that on my setup your patches are causing errors and UMS is
not working (e.g. partitions aren't exported).
I don't have enough time now to delve to your solution, but I'm
skeptical about hard setting EPs (like below).
+if (fsg_fs_bulk_out_desc.bEndpointAddress != 0x1)
+ fsg_fs_bulk_out_desc.bEndpointAddress = 0x1;
+
If possible, please align to patch set [**], so we can have the same
setup.
However, I will try to find some time to help you with the problem
(that's why I've asked for description of the problem, which you are
trying to fix).
