ERROR: could not insert module /lib/modules/cp210x.ko: Unknown symbol in module synology_geminilake_920+ #84

CrayzChris · 2023-05-01T22:37:58Z

I updated my synology DS920+ from 7.1.1-42962 Update 5 to 7.2-64551.

The device /dev/ttyUSB0 (Silicon Labs CP2102) is missing after the update :-(.

Try this:

file /lib/modules/usbserial.ko

It sounds like you have overwritten that file with something else.

ModuCZ · 2023-05-24T16:37:24Z

I can provide "usbserial.ko" file for DSM 7.2 (kernel 4.4.302) from DS720+ (geminilake).

Mine was showing same symptoms, probably overwritten by DSM 7.1 version. You can extract it from DSM 7.2 pat file after decrypting it.

Hi. I'm banging my head. I'm trying to load my Sonoff Zigbee USB. I can't get ttyUSB0 or ttyUSB1 to show up. I downloaded al the necessary files for my 7.2 upgrade and it worked before that time. Same kernel geminilake DS720+. When I run /usr/local/etc/rc.d/usb-serial-drivers.sh start nothing happens. Any advice you can lend would be appreciated. Thanks.

@schwooba try loading the required modules manually to see if any of them causes an error:

sudo insmod /lib/modules/usbserial.ko
sudo insmod /lib/modules/cdc-acm.ko
sudo insmod /lib/modules/cp210x.ko

schwooba · 2023-06-12T10:11:13Z

@robertklep thx. Here's the outcome...

robertklep · 2023-06-12T10:13:17Z

Ah okay, that means you very likely didn't follow the download instructions properly.

The correct download URL for the required module is this: https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/cp210x.ko

schwooba · 2023-06-12T11:17:24Z

Oh man. That worked. Thanks so much. It always comes down to the basics.

DeadlySin2 · 2024-01-23T08:11:44Z

Hello, i have the same ussue
I have made everything by the instruction but i get such error with all the files:
root@123:/lib/modules$ sudo insmod /lib/module/cp210x.ko
insmod: ERROR: could not load module /lib/module/cp210x.ko: No such file or directory
Or if i insert

robertklep · 2024-01-23T08:41:06Z

@DeadlySin2 modules in the path should be plural

DeadlySin2 · 2024-01-23T08:50:54Z

Sorry for error my mistake.
Synology DS920+
DSM 7.2.1-69057 Update 3
These are the commands i used to download files
sudo wget https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/cp210x.ko
sudo wget https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/usbserial.ko
sudo wget https://github.com/robertklep/dsm7-usb-serial-drivers/raw/main/modules/geminilake/dsm-7.2/cdc-acm.ko

All files now send these errors:
root@YurlovoNAS:# sudo insmod /lib/modules/cp210x.ko
insmod: ERROR: could not insert module /lib/modules/cp210x.ko: File exists
root@YurlovoNAS:# sudo insmod /lib/modules/usbserial.ko

insmod: ERROR: could not insert module /lib/modules/cdc-acm.ko: File exists

robertklep · 2024-01-23T08:56:03Z

"file exists" means they are already loaded. Also, I don't provide usbserial.ko or cdc-acm.ko from this repository since they are shipped with DSM.

DeadlySin2 · 2024-01-23T09:49:47Z

Thanks, as i can understand the drivers are instaled and work

The Conbee II module i can see. But i cant see the device ttyACM0 or ttyUSB0 in the /dev directory so these drivers are no working for my device?

robertklep · 2024-01-23T11:17:49Z

~~I don't see the cdc-acm.ko module loaded, which is probably the one that's needed.~~

Never mind, it's there. In that case, the Conbee should have been recognized, not sure why it isn't. Is it connected with a USB extension lead? That's usually necessary, especially when using USB3 ports.

DeadlySin2 · 2024-01-23T12:36:58Z

It is connected with the lead throw a hub. So i have DS920+ - USB HUB - Conbee2 and a USB cable from UPS
I tried to use
sudo insmod /lib/modules/cdc-acm.ko
But it returnes insmod: ERROR: could not insert module /lib/modules/cdc-acm.ko: File exists

robertklep · 2024-01-23T12:58:08Z

Like I said, the "File exists" error happens because the module is already loaded. Try unplugging the Conbee, then plugging it back in, then check sudo dmesg to see if there are any messages appearing that might point to a reason why it's not working.

ryanthuff1 · 2024-04-15T02:08:09Z

Sorry I'm having same issue, I have the correct file (raw), but it says wrong format when I load. I found this in dmesg
cp210x: version magic '4.4.302+ SMP mod_unload ' should be '4.4.180+ SMP mod_unload '

ryanthuff1 · 2024-04-15T02:24:37Z

well $hit I am still on 7.1 LOL. my bad.

robertklep · 2024-04-15T05:04:55Z

@ryanthuff1 most modules are also available for 7.1

pacolvin · 2024-07-29T02:09:09Z

My system is DSM is missing the cdc-acm. Anyone know where I may be able to get it? I can't get my Sonoff Zigbee 3 dongle to work after downloading and starting all of the other drivers. Not sure but maybe missing the cdc-acm.ko could be the reason.

robertklep · 2024-07-29T04:09:32Z

@pacolvin

Can you post the output of these commands:

lsmod | grep serial
lsusb -cui

Preferably in a new issue report 👍🏻
