#Hl 340 usb serial adapter linux driver install

I could probably have use the Karl’s Linux kernel, but I remembered having read that Canonical makes some changes to the Linux kernel, so instead I went to to download and install Linux 3.18 in my machine (This is 3.18.0, but with hindsights I should have gone with 3.18. So it was time for plan B, or rather option 2. Raspberry Pi doesn't have an out of the box driver for it, so plugging your device into RPI's USB won't do much other than power it. This is a very common chip, especially in those millions of esp8266-based dev boards (also often referred to as NodeMCU). I decided to go with option 1 at first, but I quickly changed my mind as there’s been a bit too many modifications between the two versions, and it started to be time consuming. A pre-compiled binary for CH340/341 (H元40/341) USB-to-Serial UART Driver for Raspberry Pi. Instructions to build a kernel module in Ubuntu are already available, but the patch for ch341 driver is for Linux 3.18.6, and Ubuntu 14.04 comes with Linux 3.13. Since I did not want to wait I decided to build ch341.ko with the patched driver, and I can now use Sigrok with my HL-340 USB-Serial adapter successfully, but I’ll write more about that in another post, and today, I’ll document the steps I followed to build the driver for my machine. A few days later, Karl Parsonn left a comment saying ch341 driver just ignored parity (UNI-T DMM use odd parity), but that he wrote a patch that should eventually make it to mainline. Finally, I gave up on Sigrok on Linux, and tested the power consumption of some Rockchip RK3288 & Amlogic S802 devices in a Windows 7 virtual machine running in my Ubuntu 14.04 host PC. Was most likely to culprit, so I decided to buy another random USB to serial dongle on eBay, and after a few weeks I received it only to find out it had the exact same VID:PID, so I was out of luck.
