The procedure may also be applied to other serial devices, but I found ch341 one of the most common one. You should see the device attached to ttyUSB* Now plug in your serial device and type in dmesg | grep ch341 Sudo cp drivers/usb/serial/ch341.ko /lib/modules/$(uname -r)/kernel This step is to avoid the version magic error. Next, find the line CONFIG_LOCALVERSION= , Uncomment it and change it to CONFIG_USB_SERIAL_CH341=m configįind the line with “ #CONFIG_USB_SERIAL_CH341” We then copy the config file to here zcat /proc/config.gz >. Fortunately, it can be easily applied to CH341 as well.ĭownload the source of your kernel from here at the bottom of the pageĮxtract the file, you will see kernel_2 inside.Įxtract kernel_2 by tar xvjf kernel_2Ĭd into the extract folder, you will see hardware folder and a kernel folderĬd into kernel folder and then cd into kernel-4.4 folder There was an outdated guide on eLinux for FTDI drivers. I found out that HL-340 can be used after CH341 driver is enabled. You might see “QinHeng Electronics HL-340 USB-Serial adapter” If you happen to have such device, by typing in command lsusb Known Devices that might have this problem: After struggling for a while, I solved the problem and decided to write this guide Some Arduino / USB Serial Converters use CH341 (or HL-340) which are not installed by the default jetpack.
