Hk.t.rt2831p738 Firmware 【Windows Ultimate】
If you bought a no-name USB tuner, check the included mini CD. Inside the Firmware or Driver folder, look for RT2831P.bin or R838.bin.
Cause: The firmware was never loaded, so the USB stack times out.
Fix: Unplug the device, delete stale firmware from /lib/firmware, and reinstall the correct .fw file. Also try a different USB port (preferably USB 2.0, not USB 3.0).
Most modern kernels (5.x+) already support the chipset, but the firmware may be missing.
Step 1 – Check kernel support
lsusb | grep -i realtek
Expected output: Bus 001 Device 003: ID 0bda:2838 Realtek Semiconductor Corp.
Step 2 – Install firmware-realtek
sudo apt update && sudo apt install firmware-realtek
Step 3 – Manually add the hk.t.rt2831p738 blob (if not auto-detected) hk.t.rt2831p738 firmware
cd /lib/firmware
sudo wget https://linuxtv.org/downloads/firmware/rtl2832u_hk_t_p738.fw
sudo chmod 644 rtl2832u_hk_t_p738.fw
Step 4 – Reload the driver
sudo modprobe -r dvb_usb_rtl28xxu
sudo modprobe dvb_usb_rtl28xxu
Check dmesg | tail – you should see:
rtl28xxu 1-1:1.0: firmware: loaded rtl2832u_hk_t_p738.fw
Step 5 – Test with w_scan or Kaffeine
w_scan -c US -f t -C -c -X > channels.conf
If you have a working device on an old Windows machine and want to extract the firmware for backup:
This is advanced and rarely necessary, but can save a bricked device.
