If it helps, here's how I installed the modules: #!/bin/bash
set -eo pipefail
echo "Make sure you runt his script as root or with sudo"
echo "Downloading modules"
cd /lib/modules || exit 1
wget 'https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/ch341.ko'
wget 'https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/cp210x.ko'
wget 'https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/pl2303.ko'

wget 'https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/ti_usb_3410_5052.ko'
echo "Downloading script to start usb modules"
cd /usr/local/etc/rc.d || exit 1
wget 'https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/usb-serial-drivers.sh'
chmod +x /usr/local/etc/rc.d/usb-serial-drivers.sh
echo "Starting usb modules"
/usr/local/etc/rc.d/usb-serial-drivers.sh start
exit 0 |

Can you check which modules are loaded? |
|
Uuugh, I just ran the command again and now it's there?!? I didn't change a thing, except rebooting Synology 🤯. |
|
Oh! Just happened again! So, after the restart it was there, and I was playing with zigbee2mqtt addon via its Addon UI, inside home assistant, inside a VM, inside synology. Here's the output of The reason I'm messing with zigbee2mqtt in the first place was that it stopped working out of the blue, apparently a known issue to be fixed on the next version. Do you think it could be either z2m, HA or Synology crashing the usb module somehow? Any other ideas? |
|
I have no idea, but I would suspect a hardware issue, either with your dongle or the cable. When it happens, are any relevant messages shown in the output of |
|
Oof, that's rough. Yeah, here it, grepped for "usb": |
|
I think these two suggest that as far as the OS is concerned, the dongle has been disconnected physically: So might be worthwhile to check if another cable (or even directly plugging it into the NAS, even though that's usually not a good idea due to interference issues) might solve it. |
|
Hmmm but in that case, if it got physically disconnected, shouldn't it NOT
appear on the lsusb command's output?
|
|
Fair point, but it doesn't change the fact that this looks like a hardware issue. Besides that, I only compile the modules and have no idea how they actually work or how to solve issues with them 😅 |
|
I'm stuck at the very same after installing DSM7.2.1-69057 Update 4 on my DS220+ (which was working totally fine with the Sonoff Zigbee 3.0 Stick. I followed all those steps and several variantions I found on the net, but no success: there is no /dev/ttyUSB0 any more. |
|
@mager33 what is the output of |
|
USBSERIAL is available There is a port assigned, after 2x reboot (once with, once without the stick plugged in) I did sudo chmod 777 /dev/ttyUSB0 and it worked again. |
|
@mager33 is the dongle connected through an extension lead? If not, it should be 😊 |
|
@robertklep you’re often mentioning to use the extension lead. So I bought AXAGON HUE-SA7BP 7-Port USB 3.0 CHARGING hub. My goal is to connect Jablotron 100+ and Home Assistant (running in Container on Synology 920+, version: DSM 7.2.1-69057 Update 5). I tried and read many topics about the issue - unfortunately I can’t still see It seems that all drivers are loaded properly, the only weird thing is: |
|
@1uba I don't see any device connected in the output of Even if there's a device connected that isn't supported by any of the drivers, it should still be visible. |
|
Thank you for your quick reply @robertklep |
|
@1uba it looks like it's presenting as two separate devices: a USB HID device (so it may act as a keyboard or a mouse or something similar) and a USB storage device (the drivers I provide only support USB serial devices). Since you're looking to add support for it to Home Assistant, take a look at this integration. |
I was originally planning to start with HACS Jablotron 100+ integration. Both - even the HASS-JablotronSystem integration are supposed to be configured with the serial port. It’s mentioned in their documentatoin: "Note: Because my serial cable presents as a HID device there format is /dev/hidraw[x], others that present as serial may be at /dev/ttyUSB0 or similar." |

Type of device
Sonoff Dongle
DSM 7.2
Linux 4.4.302+ #69057 SMP Fri Jan 12 17:02:28 CST 2024 x86_64 GNU/Linux synology_geminilake_220+
Have the modules loaded?
Yes. Or I think they are. When i manually invoke
sudo insmod /lib/modules/usbserial.ko, it returns:insmod: ERROR: could not insert module /lib/modules/usbserial.ko: File exists. Should it have returned nothing at all?Output of lsusb
Note: it appears there isn't a device assigned as expected. It used to show
/dev/ttyUSB0Other info:
I didn't change the dongle nor the cable it is connected to synology. Everything was working until my zigbee devices stopped working last night, and while investigating why i eventually saw
/dev/ttyUSB0wasn't there as it used to. I've been trying to get it back there to no avail.Contents of my /usr/local/etc/rc.d/ (does it matter specific owners/groups? That user is admin. before it was root and it wasn't working too)
