Installing CH340 drivers in Linux Mint running 5.15.0-88 kernel
Hi all, I've recently switched over to Linux Mint from Windows 10 and I'm having trouble installing a CH340 driver from Sparkfun. I've managed to unzip the contents and have it in this location: /home/user/Downloads/CH341SER_LINUX. I've tried running the files using the ./ command for both the ch34x.c and Makefile but ran into a bash issue which I'm stuck trying to figure out. Could someone please tell me how to make it work? I've already looked up a couple of different videos on Youtube but they kind of skip the explanation of how to install this driver on Linux in favor of Windows and MacOS.
Please see the attached image for the response I get in the terminal.
UPDATE: It turns out I had a bad micro USB cable. Most of the ones I was using to connect to an ESP32 board were charge only. Mint apparently had the driver for this all along. Thanks for the help everyone.
To be fair, it actually does work out of the box, but shortcut mapping doesn't really work well outside of the buttons on the pen itself and pressure curves isn't customizable yet, at least on KDE.
Some time ago I wasted about 2 hours of time because of that damn brltty, wondering why the tf the arduino was not being detected until I followed dmesg. I was very upset at the time when I found out what brltty was. Like I get some people need that but if the user did not connect a braille display during install then the daemon should never be enabled or just uninstalls during os installation.
*.c files are C source files, you can't run these directly. Run the makefile with sudo make or sudo make install (assuming you have make installed) to build (or build and install) the driver.
edit: Oops didn't read far enough into your post, you've already tried make. What error does it give you?
You don't pass in Makefile to make as it will read that file automatically. Nor you need sudo with make as compiling doesn't need any special privileges.
Step:
make: compile the code to binary
sudo make install: install the binary to your system
I did what abominable_panda suggested and it returned a "wait_queue_t" and a couple of pointer type errors. I'm not sure if that's something that could be fixed with installing something else, but I'm not at all familiar with troubleshooting on this OS yet. The troubleshooting part you mentioned is if it successfully installed but there are issues. It doesn't quite explain the initial installation part.
As for cmnybo's question, I'm trying to program a ESP32 module with the Arduino IDE. I've tried just plugging it in and hoping the driver would already be installed but lsusb doesn't show it on the results.
If it's not showing up in lsusb and there is no activity in syslog when connecting or disconnecting it, then the problem is not a driver. It's likely a bad cable or you got a dead module.
You're right about the bad cable. I have a collection of about 10 USB A to USB micro cables and only one of them showed up on lsusb! Thanks for the advice!
You don't execute C source files. They have to be compiled.
First point as someone else commented, that driver is already present in any mainstream kernel. It's very unlikely you have any need to build it.
But if you really want to build it the command will be make that will get instructions from Makefile on how to build the driver. But there will be other tools and libraries needed.
