Hello,
I bought a new USB-RS232 cable and the system loads ch341.ko for me
(Debian with kernel 3.14-2-amd64 and 3.16.0-4-amd64). However this
module does not work with my cable (/dev/ttyUSB0 appears but the
serial device doesn't work
I'm connecting it to an external modem on the RS232 side. If I use
some other program to connect to the modem, it reports modem not
responding. To debug further I'm minicom'ing to it. Once connected, I
type AT then press Enter. Screen output is pasted below (with Local
Echo set to No and Hex
I'm seeing this as well, I've got some work in progress towards this,
but not finding the time I'd hoped. CH340 devices work fine with the
current linux driver, but CH341, very very very flaky, if at all.
