Tenda aic8800dc switches successfully on one port and fails on the other

Post by random_usb_user » 25 Feb 2024, 22:15

Hey folks, been trying to solve this for the past 3 days with no luck.
It is a 3d printer that came with this wifi usb stick. At one point I accidentally took it off and since then it is no longer switching to wifi mode but only on that specific port!

When I try to switch it manually -

Code: Select all

root@mkspi:~# usb_modeswitch -K -v a69c -p 5721 -W
Take all parameters from the command line


 * usb_modeswitch: handle USB devices with multiple modes
 * Version 2.5.2 (C) Josua Dietze 2017
 * Based on libusb1/libusbx

 ! PLEASE REPORT NEW CONFIGURATIONS !

DefaultVendor=  0xa69c
DefaultProduct= 0x5721

StandardEject=1

Look for default devices ...
  found USB ID 1d6b:0003

Have you checked to see if there are any updates for your printer and USB?

I've checked and it's the latest update but the error still occurs.

Completely power off the 3D printer, unplug it for a few minutes, and then turn it back on. This can sometimes reset the USB ports and resolve issues.

I've been having trouble with my Tenda AIC8800DC switch. One of the ports is not powering on, even after I've tried resetting the switch, checking the cables, and updating the firmware. The other ports are working fine. I've connected a laptop to the faulty port, but there's no link light.
