Feb 29, 2008  Hi all, Saya punya USB to Serial (RS-232) converter, pakai driver HL-340. Tapi saya ngga tau gimana dapetin driver linuxnya. Tekken 5weeblycom download. Sudah tanya om google, tapi masih mentok.

Something between USB2.0 or USB3.0? Or kernel compilation anyways? And if so, why on old kernel 3.18 work it snoothly? Also dont work a guide.

Dmesg [ 1431.007315] usbcore: registered new interface driver usbserial [ 1431.007323] usbcore: registered new interface driver usbserial_generic [ 1431.007330] usbserial: USB Serial support registered for generic [ 1431.008619] usbcore: registered new interface driver ch341 [ 1431.008629] usbserial: USB Serial support registered for ch341-uart - its very nice that Serial support is registered, but not attached for example: to the BUS 003 Device 001: ID 1A86. (and this is important) ls /dev/tty* /dev/tty /dev/ttyS22 /dev/tty0 /dev/tty24 /dev/tty4 /dev/tty55 /dev/ttyprintk /dev/ttyS23 /dev/tty1 /dev/tty25 /dev/tty40 /dev/tty56 /dev/ttyS0 /dev/ttyS24 /dev/tty10 /dev/tty26 /dev/tty41 /dev/tty57 /dev/ttyS1 /dev/ttyS25 /dev/tty11 /dev/tty27 /dev/tty42 /dev/tty58.and so on. But nothing with ttyUSB0, ttyUSB1, or ttyACM0, ttyACM1.

Please Is here some competent person to FIX this ISUE? 26 Jan 2017; same problem from syslog Jan 26 08:36:17 USSMLTRDLinux02 kernel: [205] usb 2-1.1: new full-speed USB device number 38 using ehci-pci Jan 26 08:36:17 USSMLTRDLinux02 kernel: [291] usb 2-1.1: New USB device found, idVendor=1a86, idProduct=7523 Jan 26 08:36:17 USSMLTRDLinux02 kernel: [297] usb 2-1.1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 Jan 26 08:36:17 USSMLTRDLinux02 kernel: [299] usb 2-1.1: Product: USB2.0-Ser! I found a new ch341.c source code. And I wanted to build a module ch341.ko on ubuntu16. 04(Japanese) that kenerl- 4.4.0-81- generic, but could not build. El poder de la palabra hablada florence scovel shinn pdf free printable. I think that ch341.c was changed interface to upper module.

Ch341.c in github is about 640 lines. So I search kernel in The Linux Kernel Archives that ch341.c has same size. Then I found kernel-4.11.6(but now 4.11.7). I build kernel-4.11.6 on ubuntu16.04, I build kernel-image, but could not build kernel-headers. I install kernel-image to use dpkg command. And I use minicom to communicate HL-340, and work fine.
