[EN] USBCORE

[eriefisher]

I've been struggling to get an AX210 wifi/bluetooth combo card working. I've been hashing it out in the Debian Forum with some help. The wifi works excellent, however, I can't seem to get bluetooth hardware to be detected. Comparing some outputs one thing I saw different was usbcore. From a post he has the same card working fine and the output of:

Code: [Select]

lsusb | grep bt
btusb 81920 0
btrtl 36864 1 btusb
btintel 73728 1 btusb
btbcm 24576 1 btusb
btmtk 32768 1 btusb
bluetooth 1101824 38 btrtl,btmtk,btintel,btbcm,bnep,btusb,rfcomm
usbcore 425984 7 xhci_hcd,usbhid,btmtk,uvcvideo,btusb,xhci_pci,hid_logitech_hidppThis show usbcore loaded. With Siduction this is not so and no sign of it on my system. I'm wondering if this is intentional or an oversight during the build?

Code: [Select]

uname -r
6.18.6-1-siduction-amd64

I should add, I installed the latest Debian RT kernel and usbcore is there and loaded. This, however did no solve my problem.

usbcore will only show as a module, if CONFIG_USB=m is set in kernelconfig, but we have CONFIG_USB=y, so it's not build as module.

Oh, ok great. It does not seem to affect anything anyway as everything usb seems to work just fine.

If anyone has some time and can offer some insight to get bluetooth working for me I would appreciate it.

Only one simple thought:

Are you using PipeWire? Then package libspa-0.2-bluetooth must be installed.

Code: [Select]

apt policy libspa-0.2-bluetooth
libspa-0.2-bluetooth:
  Installed: 1.4.10-1
  Candidate: 1.4.10-1
  Version table:
 *** 1.4.10-1 500
        500 https://deb.debian.org/debian sid/main amd64 Packages
        100 /var/lib/dpkg/status

Quite a lot of issues and hints regarding AX210 and Linux.

For example, "...deactivate WiFi and BT is working..."

Or: "..It was indeed the antennas. I ordered this: https://www.amazon.co.uk/gp/product/B08 … UTF8&psc=1, installed it, and now it's working..."
(source: https://bbs.archlinux.org/viewtopic.php?id=280283)

Most weird and funny: "..use adhesive tape to insulate PIN 54 of the card..", see below:

@TE: Hast du dir mal die Bewertungen durchgelesen? Evtl. hast du das gleiche Problem wie in der 1. Bewertung:

"Nach einer kleinen Recherche im Internet stellte sich heraus, dass einige Notebook-Hersteller gewisse PINs auf der M.2 Karte scheinbar deaktivieren, wenn das BIOS die Karte nicht erkennt.

Die Lösung: PIN 54 (Bluetooth) und PIN 56 (WIFI) mit einem winzigen Stückchen TESA-Klebestreifen unter Zuhilfenahme eines Vergrößerungsglases und einer Pinzette abkleben und in den M.2 Schacht einsetzen. Auf diese Weise werden Bluetooth und WIFI hardwareseitig aktiviert (unabhängig von etwaigen BIOS-Einstellungen).

Das WLAN als auch das Bluetooth-Modul lässt sich danach per Software immer noch deaktivieren und aktivieren."


Der Verfasser hat auch ein Bild angeheftet auf dem die beiden Pins markiert sind...

That is all I can tell. Good luck!

I know it's not just the antenna. The card is not being detected as far as bluetooth is concerned. Mine is a different card than the one in the link. Single notch and two retaining screws. So the pins would likely be different. I did come across the post from the Arch forum in my research.
