[Kernel-packages] [Bug 1527491] Re: QinHeng Electronics HL-340 USB-Serial adapter

[Seiichi Nakashima]

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. 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.

also I build kernel-4.11.6 on slackware64-14.2, HL-340 also work fine.

Try the latest mainline kernel? This commit [1] seems to address the
issue.

[Daniel Liabeuf]

Module ch341 still defect on kernel 4.9 .
In my case, the correction proposed in #9 works (thanks to the author).

Tips: How to build module without the entire kernel
# cd drivers/usb/serial
# make -C /lib/modules/$(uname -r)/build M=$(pwd) modules

I do observe the associated access is ehci-pci, whereas the original

Also I have some CH341 bases RS485 interfaces, they work just fine, same

[Thomas]

You can rebuild the kernel by following these steps

https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel

the file you will need to edit is here

drivers/usb/serial/ch341.c

&&

http://lxr.free-electrons.com/source/drivers/usb/serial/ch341.c

I'm sure you can recompile things by module but from memory the process
is lengthy and difficult. This is the easiest option -- although re-
compiling the kernel will take a while. Hopefully a patch will come
soon.

[Kernel-packages] [Bug 1527491] Re: QinHeng Electronics HL-340 USB-Serial adapter

[wlarsong]

I have these adapters

/* expect two bytes 0x56 0x00 */
r = ch341_control_in(dev, 0x95, 0x2518, 0, buffer, size);
if (r < 0)
goto out;
/*Comment this line out and recompile*/ //r = ch341_control_out(dev, 0x9a, 
0x2518, 0x0050);
if (r < 0)
goto out;

Everything works now

[Kernel-packages] [Bug 1527491] Re: QinHeng Electronics HL-340 USB-Serial adapter

[Stanislav Petrek]

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 ?


Thank you

I try to run Arduino Nano with ch341, but nothing work. 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:
