The device hangs if SPI transaction data size is larger than 121 bytes.

This is a deadlock between full CDC receive buffer (which is 128 bytes) and SFP server waiting for full packet to be available. Quick fix - increase the buffer to 256 or 512 bytes. Better fix - parse binary packets on the go (just like ascii packets are).
