Hi Hans,

If I understand correctly, I need to set bufsize in struct usb_config as
follows:

         [UMASS_T_BBB_DATA_READ] = {
                 .type = UE_BULK,
                 .endpoint = UE_ADDR_ANY,
                 .direction = UE_DIR_IN,
                 .frames = 128,
                 .bufsize = UMASS_BULK_SIZE * 128,
                 .flags = {.proxy_buffer = 1,.short_xfer_ok = 1,
UMASS_USB_FLAGS}, .callback = &umass_t_bbb_data_read_callback,
                 .timeout = 0,   /* overwritten later */
         },

Thanks
Aman

Yes, that is correct: "* 128"

Do you see any problems using this setting? Also note that unless you specify
ext_buffer in flags, the USB API will allocate a buffer for you.
