Attempting to Setup TP-Link Archer T3U Plus, Discovered USB Not Working (!) [SOLVED, (with T3U Driver Info)]

Support Network
1

Relative newbie here. I was looking around the forums looking for a solution to setting up my new Archer T3U Plus and nothing was working. Getting ready to post and ask for help, I noticed that my inxi output showed:

USB:
  Message: No USB data found. Server?

Confused, I checked to see if my laptop could even see my new wifi dongle at all:

[zak@server47 ~]$ lsusb
lsusb: error while loading shared libraries: libusb-1.0.so.0: wrong ELF class: ELFCLASS32

Checking around again, I could see that this problem pops up in relation to installing certain pieces of software, and so the fix usually involves tweaking that software installation process. But that’s not what I’m doing, my usb just seems to have blinked out on me, so, I’m not sure what to do — help!

This should not be necessary - Manjaro uses tlp

I understand the confusion - care to explain how did that happen on a 64-bit system?

It would be interesting to see the pacman.log - could you post the log on a pastebin site? It is easily done using e.g. the package pastebinit then do

pastebinit -b dpaste.com -i /var/log/pacman.log

Ok, I fixed the usbcore.autosuspend, thank you.

Not sure how I got libusb-1.0.so.0 for a 32 bit system…how do I fix that?

And here’s my pacman.log that you asked for.

Thanks for the help!

TL:DR - > Reinstall the package

As one would think that libusb would be something found on every system - I checked the databases - using pacman -F libusb - and there is no trace of libusb.

Then I checked your pacman.log → no trace either (because the pacman.log is your log - not the ISO log) - the package is registered in the file /rootfs-pkgs.txt

Then I checked Package - libusb - Discover Packages On Manjaro Linux → libusb is v1.0.24-2

Then I tried this and this shows the package content

pacman -Fl libusb

Then a check on the file

➜  ~ file /usr/lib/libusb-1.0.so
/usr/lib/libusb-1.0.so: symbolic link to libusb-1.0.so.0.3.0
➜  ~ file /usr/lib/libusb-1.0.so.0.3.0 
/usr/lib/libusb-1.0.so.0.3.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=a06af3fb394423604e1ab1e0c6d7e85c228ffce1, stripped

It seems the discover site is slightly out of sync with branch-compare - I think that is going to adjust itself at some point @codesardine

  • branch-compare has v1.0.24-2
  • discover has v1.0.23-2

I did a libusb reinstall, and it worked – my USB is back – thank you!

For anyone interested, I was then able to get my TP-Link Archer T3U Plus working by installing the rtl88x2bu-dkms-git driver from the AUR repos. I also installed dkms (of course) & the linux headers for my kernel. I did a reboot and the T3U was recognized.

I’d also like to share a link to this archived post on how to identify the driver you need and go about installing it. The OP is right that it too often happens that we newbies will willy-nilly try different methods from old posts without checking our hardware/system first (Lord knows I have). But I know I’ll be following the advice in this post from now on. :wink:

Thanks again for the USB help, @linux-aarhus!
