Error: USB error: Operation timed out on WCH-Link-CH549

Hi, I just got these WCH-Link-CH549.

Unfortunately, they come with old firmware (v1.05). So I updated to new firmware bundled with MRS zip file MounRiverStudio_Linux_X64_V220/MRS-linux-x64/resources/app/resources/linux/components/WCH/Others/Firmware_Link/default/WCH-Link_APP_IAP_RV.bin.

Caused by:

I couln't find another firmware version.. If I could use another version let me know.

If it is related, I get similar error on WCH's openocd:

openocd -f /home/ajit/.local/opt/OpenOCD/OpenOCD/bin/wch-riscv.cfg -c 'init; halt; program build/ch582_blinky.bin; reset; wlink_reset_resume; exit;'

Note that if I use a different probe it is working (different kind), so nothing wrong with the setup..

It works now.. Downgraded to version 2.8 from here.
