Mercusys MA30H

[nicolascolla]

Hello, @RinCat and thank you very much for maintaining this fork.

I have a Mercusys MA30H, and the official drivers page (https://www.mercusys.com/en/download/ma30h/v2) offers the sources of the RTL88x2BU driver (that fail to build on newer kernels), so I'm pretty sure this is a RTL88x2BU device. However, after building the driver from this repo, the Wi-Fi dongle is still not recognized.

dmesg output:

[  642.056301] usb 1-1.2: new high-speed USB device number 4 using ehci-pci

lsusb output:

Bus 001 Device 004: ID 2c4e:0107 Mercucys INC 802.11ac NIC

Do you know if there's any way in which I could get it working?
Thank you very much!

Hi @nicolascolla, this one is new USB device ID, so I will need to add it.

Also congratulations on finding a new driver version. I have not seen a new version of this driver for a long time. I will try to update it today.

[RinCat]

Update the driver, now it should works. 8159d98

Hello, @RinCat, and thanks a lot for the quick response. Unfortunately, it seems like my dongle is still not being detected. It still appears as a regular USB device and no network interface is added when I plug it in, even if I manually load the driver with modprobe. Do you know why that might be the case? And is there anything else I could test?

[RinCat]

Did you deleted old module and rebuild it from the new source?
Run dmesg -W as root, then plug in the USB dongle should shows something

I ran sudo make uninstall from the source folder, then cloned the new version of the repo and recompiled.

This is what dmesg shows when the dongle is plugged in:

Did you removed the old loaded module by run modprobe -r 88x2bu?

[nicolascolla]

Instead of doing that, I just rebooted the machine.

[RinCat]

remove this file and rebuild again /lib/modules/$(uname -r)/kernel/drivers/net/wireless/88x2bu.ko

[nicolascolla]

No luck, unfortunately. Steps taken:

$ sudo rm /lib/modules/$(uname -r)/kernel/drivers/net/wireless/88x2bu.ko
$ cd src/RTL88x2BU-Linux-Driver/
$ make -j4
...
$ sudo make install
install -p -m 644 88x2bu.ko  /lib/modules/5.15.0-113-generic/kernel/drivers/net/wireless/
/sbin/depmod -a 5.15.0-113-generic
$ sudo modprobe -r 88x2bu

The dongle still shows up as a regular USB device, as in #237 (comment)

[RinCat]

Can you run grep -r 0x0107 in the driver dir and see it report the usb id there?

[nicolascolla]

Yes, the changes of the last commit are there:

$ grep -r 0x0107
include/rtw_btcoex.h:	HCI_BT_COEX_NOTIFY								= 0x0107,
os_dep/linux/usb_intf.c:	{USB_DEVICE_AND_INTERFACE_INFO(0x2c4e, 0x0107, 0xff, 0xff, 0xff), .driver_info = RTL8822B}, /* Mercusys MA30H V2 */

[RinCat]

which system are you using? Also the installed kernel is the same as current running?

[nicolascolla]

I'm running Linux Mint 21.3 Virginia, and the kernel running is the same as the one that is installed, and the one the driver was compiled for: 5.15.0-113-generic

$ uname -sr
Linux 5.15.0-113-generic

What's the result after run modprobe 88x2bu in dmesg?
