How to make OS see Mercusys MU6H?

Question

linux

OC: Debian 10
Kernel: 4.19.0-18-686-pae
Device: Mercusys MU6H

It was necessary to connect this whistle to a PC. I installed the driver version rtl8821CU, it was installed normally. At the same time, only two network interfaces remained in the ip a output: local and Ethernet. dmesg says it's a drive:

usb 1-5: New USB device found, idVendor=0bda, idProduct=1a2b, bcdDevice= 2.00
usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-5: Product: DISK
usb 1-5: Manufacturer: Realtek

lsusb output:

Bus 001 Device 003: ID 0bda:1a2b Realtek Semiconductor Corp.

Is there any way to make the OS see the adapter as a "network device" and not as a "drive"?

upd:
Installed usb_modeswitch and modemmanager, didn't help.
I tried loading the driver manually:

sudo modprobe usbserial vendor=0x0bda product=0x1a2b

A ttyUSB0 was created, which disconnected after 5 minutes, but dmesg made the following conclusion:

scsi 2:0:0:0: Direct-Access             Realtek            Driver Storage             1.00             PQ: 0             ANSI: 0         CSS

Also usb for some reason reboots sometimes:

usb 1-5: reset high-speed USB device number 6 using ehci-pci

.
I do not know, maybe because of this it is not determined, although it is unlikely.

The problem is still relevant.

Answer 1

The problem was solved by switching to Debian 11 and updating the kernel to 5.10. As I understand it, the 4.19 series kernel is not supported by 8821cu firewood in principle.

Answer 2

Try installing the modemmanager and usb-modeswitch packages, they just switch the usb device from storage mode to network device
