I try to modify these codes to improve the transmission rate of the MSC equipment and the MTP_TX_SIZE and MTP_RX_SIZE has been modified, but the transmission rate has not been improved. For beginners, it is not clear which definitions are helpful for speed improvement. Could you give me some suggestions?
Code:
#elif defined(USB_MTPDISK)
#define VENDOR_ID 0x16C0
#define PRODUCT_ID 0x04D1
#define MANUFACTURER_NAME {'T','e','e','n','s','y','d','u','i','n','o'}
#define MANUFACTURER_NAME_LEN 11
#define PRODUCT_NAME {'T','e','e','n','s','y',' ','M','T','P',' ','D','i','s','k'}
#define PRODUCT_NAME_LEN 15
#define EP0_SIZE 64
#define NUM_ENDPOINTS 4
#define NUM_INTERFACE 2
#define MTP_INTERFACE 1 // MTP Disk
#define MTP_TX_ENDPOINT 3
#define MTP_TX_SIZE_12 64
#define MTP_TX_SIZE_480 512
#define MTP_RX_ENDPOINT 3
#define MTP_RX_SIZE_12 64
#define MTP_RX_SIZE_480 512
#define MTP_EVENT_ENDPOINT 4
#define MTP_EVENT_SIZE 32
#define MTP_EVENT_INTERVAL_12 10 // 10 = 10 ms
#define MTP_EVENT_INTERVAL_480 7 // 7 = 8 ms
#define SEREMU_INTERFACE 0 // Serial emulation
#define SEREMU_TX_ENDPOINT 2
#define SEREMU_TX_SIZE 64
#define SEREMU_TX_INTERVAL 1
#define SEREMU_RX_ENDPOINT 2
#define SEREMU_RX_SIZE 32
#define SEREMU_RX_INTERVAL 2
#define ENDPOINT2_CONFIG ENDPOINT_RECEIVE_INTERRUPT + ENDPOINT_TRANSMIT_INTERRUPT
#define ENDPOINT3_CONFIG ENDPOINT_RECEIVE_BULK + ENDPOINT_TRANSMIT_BULK
#define ENDPOINT4_CONFIG ENDPOINT_RECEIVE_UNUSED + ENDPOINT_TRANSMIT_INTERRUPT
At the same time, when running MTP-test-integrity sketch, I found that the SSD connected through the USB interface seems to be unrecognizable. I speculate that the reason is that the MSC device is defined as a device that “Removable Device: NO”. Could you give me some advice？
I got the relevant codes from the following : https://www.github.com/kurte/MTP_Teensy
