quartus programmer linux fails and disconnects driver

FPGA programmer on Ubuntu 18.04 fails to program S10DX device with 24Mhz Jtag frequency.

Changing frequency causes the programmer driver to unload.  Re-enabling the driver resets the Jtag default frequency to 24Mhz. 

driver re-enabled with

sudo killall jtagd
sudo chmod 755 /sys/kernel/debug/usb/devices
sudo chmod 755 /sys/kernel/debug/usb/
sudo chmod 755 /sys/kernel/debug/
sudo mount --bind /dev/bus /proc/bus
sudo ../intelFPGA_pro/20.2/quartus/bin/jtagd
sudo ../intelFPGA_pro/20.2/quartus/bin/jtagconfig

HI, can you try to change the JTAG frequency to 16 MHz? Any idea what was the error message obtained when failed to program.
