The previous handshake improvement (dad27fc) only checked for PID 0x3 to identify BROM mode, but this broke compatibility with devices using custom vendor/product IDs for BROM, such as Sony phones (0x0FCE:0xF200, 0x0FCE:0xD1E9, etc.).
BROM does not expect the initial 0xa0 byte and will hang if it's sent. Workaround this by expanding the BROM detection logic to include all known BROM PIDs.
