Maximum packet size of a bulk endpoint depends on the bus speed of the device. For full speed, high speed, and SuperSpeed; the maximum packet sizes are 64, 512, and 1024 bytes respectively.
USB is an industry standard, 'user-friendly' method of transferring data between a host device (such as a computer) and a peripheral device (for example, a mouse).
The Universal Serial Bus (USB) specification stipulates five data transfer rates: USB 1.0/Low-Speed: 1.5 Megabits per second (Mbps) USB 1.1/Full-Speed: 12 Mbps. USB 2.0/Hi-Speed: 480 Mbps. USB 3.0/SuperSpeed: 5 Gbps.
Bulk Transfers. Bulk Transfers are used for data which are not of the type Control, Interrupt, or Isochronous. Reliable exchange of data is ensured at the hardware level using error detection. Data are transferred in the same manner as in Interrupt Transfers, but have no defined polling rate.

Both USB A and USB C connectors are used to facilitate 5 Gbps and 10 Gbps (USB 3.2 Gen 1 and Gen 2) connections. USB C is also used to facilitate the 20 Gbps (USB 3.2 Gen 2×2), 40 Gbps (USB4), and 80 Gbps (USB4 V2) connections.
USB 2.0 transfers data at a top speed of 480 megabits per second (Mbps), while USB 3.0 can transfer data at up to 5 gigabits per second (Gbps). You can identify USB 3.0 connectors by their blue colour and initials SS, which stand for 'SuperSpeed'.
The maximum packet size of the default endpoint depends on the speed of the device. The default endpoint of a high-speed device is 64 bytes; low-speed device is 8 bytes. The host acknowledges the data transaction by sending an ACK packet (#452) to the device. Let's calculate the amount of data returned.
The maximum size of a TCP packet is 64K (65535 bytes).
