Mr. Harald Welte. Very glad you can reply me. Let me explain first, I added simtrace-dfu-flash-latest.bin on simtrace2 through dfu-util. Also add sudo adduser $USERNAME dialout.Do I also need to flash simtrace-cardem-dfu.bin at the same time? Does simtrace2 need two bins? please tell me. What I want to achieve is to emulate my sim card remotely. Keep the sim inside the card reader. Connect the mobile phone to simtrace2, so that the mobile phone can read the card information. And the registration is successful. Calls are available. The mode I am running is three vmbox virtual machines, one with bankd installed, one with server installed, and the last one with client-st2 + simtrace2-utils installed. I have not installed a shell. Do I need to install a shell on client-st2? It shouldn't be a must-install software, right?

Cannot claim interface: LIBUSB_ERROR_INVALID_PARAM
DMAIN ERROR user_simtrace2.c:430 can't open USB device

This is all I do on the computer client2-st2. (The premise is that my card reader has been connected to the server。As shown below)

I use the official card reader, but I don't know why it shows 8 ports. It may be that my osmo-remsim-bankd -n is not set properly.

This is all my operations, please help me to correct the error. Thank you very much.
