 Use-scatter-gather-lists-for-large-bulk-transfers

Hi Hans, Alan, Greg,

commit 3d97ff63f8997761f12c8fbe8082996c6eeaba1a

    usbdevfs: Use scatter-gather lists for large bulk transfers
    
breaks an usb programming cable over here. The problem is reported as
"bulk tranfer failed" [sic] by the tool, and bisection leads to this
commit. Reverting on top of 3.6 solves it for me.

I am happy to test alternatives.

Thanks,
Henrik
