Start by determining whether you have a compliance obligation in a state. If so, register with your state's taxing agency before collecting any sales tax. After you've gone through the state's registration process, you are then permitted to collect sales tax on your transactions.
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.

If you are using a regular cable (max length of 5 meters for 2.0 and max length of 3 meters for 3.0/3.1) with an active cable, then the maximum length for USB 2.0 is 25 meters (about 82 feet) and the maximum recommended length for USB 3.0/3.1 is 15 meters (about 49 feet).
The maximum packet length for full-speed USB communication is 64 bytes. So the data will be transferred in chunks of 64 bytes and needs to be reassembled on the other end. USB CDC is based on bulk transfer endpoints and implements a data stream (also known as pipe), not a message stream.
Each USB transfer is one packet, which can be up to 64 bytes if using bulk type. If you want to send more than 64 bytes, you have to use multiple packets.
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.
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.
Try to reproduce the error by sending a packet of bytes whose length is a multiple of 64 bytes using USBD_CDC_SetTxBuffer/USBD_CDC_TransmitPacket functions. The maximum packet length for full-speed USB communication is 64 bytes.
