[SOLVED] USB device keeps disconnecting and reconnecting

Hello! I installed Arch Linux a few weeks ago. I thought that after using Mint for a while, I would be able to use Arch, but apparently not, since I have this problem that seems simple but I can't solve.

My wireless USB wifi adapter keeps disconnecting and reconnecting, and I don't have a clue why. It started happening a day or a few hours ago.

The USB is a TP-LINK Archer T3U.

Re: [SOLVED] USB device keeps disconnecting and reconnecting

Well, you are able to use archlinux - just your usb dongle isn't tongue

Dec 29 17:29:40 ArchPC kernel: rtw88_8822bu 2-3:1.0: Firmware version 30.20.0, H2C version 14

Looks like you've installed https://archlinux.org/packages/core/any … e-realtek/ ?

Dec 29 17:29:36 ArchPC kernel: usb 1-3: USB disconnect, device number 8
Dec 29 17:29:39 ArchPC kernel: usb 2-3: USB disconnect, device number 8
Dec 29 17:29:42 ArchPC kernel: usb 2-3: USB disconnect, device number 9
Dec 29 17:29:44 ArchPC kernel: usb 2-3: USB disconnect, device number 10

https://wiki.archlinux.org/title/Power_ … utosuspend - "usbcore.autosuspend=-1"
nb that userspace power management tools can and will override that, you'd have to configure it there as well.

Dec 29 17:29:43 ArchPC kernel: rtw88_8822bu 2-3:1.0: mac power on failed
Dec 29 17:29:43 ArchPC kernel: rtw88_8822bu 2-3:1.0: failed to power on mac

Did he dongle work on your mint system in the same HW config?
Have you tried a different usb port (these things can draw quite some power)?

rtw88_usb.switch_usb_mode=N

I edited both things in the kernel parameters (also, you and this issue helped me understand how to configure the kernel parameters tongue) 

usbcore.autosuspend=-1
rtw88_usb.switch_usb_mode=N

so I'm not sure which one did it but...

IT WORKED!!! THANK YOU SETH!!! I love you. This made me think, maybe archlinux it's not my thing, but anyway, I'll keep scratching my head, because why not?

now im writing this from the best distro in da world big_smile

There's actually a fairly easy way to determine that tongue
If it's the autosuspend, as the linked article points out, you can limit that to specific devices (though it's often just annoying w/ input devices and less relevant w/ usb keys anyway)

Re: [SOLVED] USB device keeps disconnecting and reconnecting

Thanks, seth, you are the man.  For those who have the same problem, I also changed the usb to a different port (USB3.0).
