Scenario B: USB Tuners & PC Peripherals

For USB dongles (utilizing chips from Silicon Labs, MaxLinear, or Rafael Micro):

• Driver Signing: A "v240" update for a PC SDK often deals with OS compatibility. For example, ensuring the device works on Windows 10/11 or newer Linux kernels (Kernel 5.x/6.x).
• Bug Fixes: Resolving USB packet loss that causes high Bit Error Rates (BER) on high-bitrate 1080p streams.

Breaking Change:

The old ioctl command FE_SET_PROPERTY for tuning now requires an additional flag FE_T2_MULTI_STREAM. Without it, the demodulator will default to DVB-T mode, resulting in "No Signal" errors for T2 muxes.
