Problem with modeswitch: change of Product ID

[adonf92]

Hello,
I tested with 2 different distributions, Fedora on PC and Raspberry Pi OS on Pi 5: same symptoms.
The compilation goes well, but when I insert the key, the Product ID is "1a2b", then after passing usb_modeswitch (through udev), the ProductID changes to "c832", and the driver is not loaded.

Hi @adonf92

I am already working on why we have so many modeswitch problems with Realtek's WiFi 6 adapters. It really is a problem.

It might work better to solve this problem if I give you access to the new driver that I am working on for the rtl8852/32bu. I just sent you an email with an invitation so I hope to see you there. Remember to fully remove this driver before cloning and installing the new one:

$ sudo sh remove-driver.sh

Hi @morrownr

I gladly accept your invitation !

Great! Check your email. I just opened the repo for testing yesterday so you are one of the first. I need reports.

Oops!
Sorry, I didn't check the "supported-device-IDs" file and I realize that I'm not using the right driver ...
Indeed the chip of my key is a "c832", so a "cu" model and not a "bu".
I just compiled the "rtl8852cu-20240510" driver, and my key is recognized.
I suppose it is not necessary for me to test the development version rtl8852bu?
Sorry again ...

No problem. I took you out and you found the one that you need. I just opened the one for the rtl8852/32cu this last week. It needs more testing so please report how you find the driver. Also, this driver already has an Issue:

Multi-state (Windows driver onboard) issues go here

Please report your modeswitch issue so I can continue documenting just how bad the problem is. By the way, modeswitch is not a problem with the driver.

FYI: If you still have time to send your adapter back for your money back, you might want to do so. Here is a message that I have posted:

It would be a good idea to read menu items 1 and 2. Let me know if you have any questions.
