[random_usb_user]

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 ...
