[argyllcms] Re: DTP94 doesn't seem to work in 1.3.0

Thanks for the debug. Looking at the urb values, I think this is a bug in
libusb, triggered by your system supporting bulk continuation.

In argyll/libusb1/libusb/os/linux_usbfs.c line 1402, change:

        if (supports_flag_bulk_continuation)
                urb->flags = USBFS_URB_SHORT_NOT_OK;
        if ((urb->endpoint & LIBUSB_ENDPOINT_IN) && 
                urb->flags = USBFS_URB_SHORT_NOT_OK;

and see if this fixes the problem.
