Dear Lukasz Majewski,

> This happens with dfu-util (debian version: 0.5), which address non
> standard requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to
> device. Without this fix, the above request is STALLED, and hence causes

> Error obtaining DFU functional descriptor
> Warning: Assuming DFU version 1.0
> Warning: Transfer size can not be detected
> ...
> Warning: Trying default transfer size 1024

> This fix allows passing non-standard request to function setup code, where

> Tested at: Trats (exynos4210)
> Tested with:DFU and UMS gadgets
Can you please repost all the patches you want applied on u-boot-usb ? I'm
completely lost in all this DFU stuff.
Best regards,
Marek Vasut
