screen starts, but doesn’t work. The usb-relevant dmesg’s are:

Screen also throws an error (which gets blanked out, but is captured by the serial console):

# screen /dev/ttyUSB0 115200
/dev/null/utmp: Not a directory
Karl Palsson commented on 13.09.2016 15:23

Try with picocom, that looks like screen is trying to use utmp for locking or something? Arguably a bug with screen.

 picocom -b 115200 /dev/ttyUSB0

Mathias Kresin commented on 13.09.2016 16:37

utmp is implemented only as stub in musl. Therefore utmp support needs to be disabled in screen, which it at least possible with commit df1c012227c95dd7aafe8706f4537445ba8f5d48.

But screen is part of the openwrt (external/additional) packages feed and issues for these packages are tracked at https://github.com/openwrt/packages/issues.

I'll close the report here. Please open a new issue at the location mentioned above. Fell free to forward the information I've provided.

Edit:

Reopened the bug after getting pointed to the real issue this report is about:

I tried picocom, it gives the same kernel message:

[  122.770000] pl2303 ttyUSB0: pl2303_set_control_lines - failed: -145
Russell Senior commented on 14.09.2016 00:36

I tried an ftdi usb-serial cable with a loopback wire (connecting tx with rx), and that worked in picocom and screen. So, ftdi = okay, pl2303 = broken on dir860l-b1.

Russell Senior commented on 14.09.2016 05:45

not a screen bug

Russell Senior commented on 14.09.2016 08:32

The pl2303 usb-serial chip has historically worked fine on OpenWrt platforms, going back to the ancient days (circa 2006) with a pl2303 built in to USB-GPS devices plugged into Netgear WGT634U and as recently as OpenWrt r49063 from late March 2016 on ramips AsiaRF AWM002.

Most recent revision with the failure is LEDE r1591. Earliest LEDE version tested on mt7621 was r1279-gc769c1b, which also failed.

Suggest changing the title to "usb-serial (pl2303) failures on mt7621 dlink dir860l-b1".

Russell Senior commented on 14.09.2016 09:26

The physical device is out of my regular kit bag that I use regularly and works fine on my desktop, and has worked fine in the same AsiaRF AWM002 as referenced above, so the adapter itself is okay. I have also tried 4 different pl2303-based devices, all of which work in my Ubuntu 14.04 laptop. I think we can rule out a bad pl2303.

Russell Senior commented on 14.09.2016 10:30

Plugging a usb2 hub into the dlink's usb3 host port, and then plugging the pl2303 into the hub, and it works fine.

It would be nice if someone else with an mt7621 or a dlink dir860l-b1 could try to replicate this problem.

hngsvtdu@sharklasers.com commented on 22.11.2016 02:07

Is the usb2 hub you plugged into external powered?

Russell Senior commented on 22.11.2016 20:55

Not sure it's relevant, but no, the usb2 hub was not powered externally. The pl2303 usb-serial draws very little power. Nothing else was plugged into the usb2 hub.

I can confirm this, tested on DIR-860L B1 running LEDE r2762-ed69e93.

do i need to install kmod-usb-ohci OR kmod-usb-uhci after installing kmod-usb-serial-ch341? don't think so..?!?

"do i need to install kmod-usb-ohci OR kmod-usb-uhci after installing kmod-usb-serial-ch341? don't think so..?!?"

No, does not help

Jan Marti commented on 25.08.2018 21:53

WHY NO ANSWER?!?

Jan Marti commented on 25.08.2018 23:51

PLEASE FIX THAT PROBLEM!!

Anonymous Submitter commented on 26.08.2018 00:39

We are not your personal support service and shouting really isn't appreciated.

Jan Marti commented on 26.08.2018 01:32

anyway, i was thinking it's positive when i submit some problems...?

maybe not... however. is it possible to compile the source code as a kernel module on version 18.06.1 / kernel 4.9.120 as a kernel module, without to compile the whole kernel?

Jan Marti commented on 01.09.2018 14:27

Problem is solved by using a FTDI USB-RS232-Adapter!!

Russell Senior commented on 01.09.2018 16:23

Jan, yeah, I mentioned the ftdi working two years ago in the original wave of reporting (13.09.2016 17:36), however for the reasons mentioned I don't consider one device working as solving the other group of devices not working.
