What is the deal with usbserial kernel module in current Ubuntu version? I cannot install any drivers, which depend on usbserial.ko.
How I got to this:
When I connect CP2102 Virtual COM Port (VCP) adapter to USB I get this output:
[ 1893.942663] usb 1-1.1.4.2: new full-speed USB device number 12 using ehci-pci
[ 1894.052823] usb 1-1.1.4.2: New USB device found, idVendor=10c4, idProduct=ea60

[ 1895.067579] cp210x: Unknown symbol usb_serial_deregister_drivers (err 0)
[ 1895.067595] cp210x: Unknown symbol usb_serial_register_drivers (err 0)
$ lsmod | grep 210x
and $ lsmod | grep usbserial
outputs nothing
Then I tried to rebuild the driver. Downloaded new CP210x driver form http://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
$ make
$ cp ./cp210x.ko /lib/modules/4.8.0-58-generic/kernel/drivers/usb/serial/cp210x.ko
$ insmod /lib/modules/4.8.0-58-generic/kernel/drivers/usb/serial/cp210x.ko
insmod: ERROR: could not insert module /lib/modules/4.8.0-58-generic/kernel/drivers/usb/serial/cp210x.ko: Unknown symbol in module
Also $ modinfo usbserial
outputs
filename: /lib/modules/4.8.0-58-generic/kernel/drivers/usb/serial/usbserial.ko
modinfo: ERROR: could not get modinfo from 'usbserial': No such file or directory
My system info: 4.8.0-58-generic #63~16.04.1-Ubuntu SMP Mon Jun 26 18:08:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
What is going on here and how to fix it? And how to get drivers up and running?
Thank you in advance!!
