On the other hand, the drivers I used on Windows were off the disk that came with the device, whereas the Linux drivers come with the OS.
#Ch341 windows 10 windows 10#
Since the device worked fine on Windows 10 through RealTerm, I am wondering if there’s something odd about the drivers on Linux. OK, tried that, did not work, copied all the original modules back.

Next, change module code to include the PL2303_QUIRK_UART_STATE_IDX0 Now, pl2303 is appearing where ch341 was previously. modprobe with force $ sudo modprobe -force pl2303 Go to actual modules dir $ cd /lib/modules/4.9.0-7-amd64/kernel/drivers/usb/serialĬopy in the old one $ sudo cp /path/to/new/pl2303.ko. OK, copy it there (after backing up the old one).ġ7.

So I recompiled the two modules and moved the vendor and product ID information out of ch341 and into pl2303. I am wondering if the vendor/product info should be associated with pl2303 instead of ch341. If I unplug and replug the USB device, ch341 is reloaded. If I use modprobe or rmmod to remove ch341 and insert (the modern version of) pl2303, the /dev/ttyUSB0 device vanishes. c file that can only be compiled against outdated Linux kernel headers, so is no use). $ modinfo ch341Ĭonfirms that it is the one that is associated with the vendor and product above, but the CD that came with the converter provides pl2303.c (a.

Using lsusb, I get vendor=0x1a86 product=0x7523Īnd lsmod | grep USB gives a bunch of stuff, including showing that usbserial and ch341 have been loaded. Playing with the various options makes no difference.

If I use GTKterm to send hex codes, I find that 0x19, 0x39, 0x59 etc up to 0xF9 all print ‘y’ (correct code, 0x79).

When I try to send characters to the serial device (just a thermal printer), I find that they’re all messed up. To use it as a terminal I expect I’ll need a null modem cable but for now one thing at a time.Īnyway, when I plug it into my Linux box, /dev/ttyUSB0 is created (good) and I can send characters to the printer but it does not work properly. But it doesn’t work on Linux, making me wonder if there’s a problem with the drivers. I can verify that using drivers that came on the CD, it works on Windows 10 - see this post.

USB to serial cable plus driver disk and DB-9 to DB-25 adapter. From ebay - a USB to DB-9 (actually DE-9) cable ($4), plus a DB-9 to DB-25 adapter - to print from a modern machine like my NetBook. Short story to save reading the rest: I did not get it to work and may have bricked the typewriter.įirst, need cables.
