USB, Bluetooth and Wifi stop working after a new Java installation.

Hello everyone!

Desperate as I can be, I come here looking for some help.

Disclaimer!!! I am not a regular Linux user.


So, we are working with an industrial tablet where an Oracle Linux Server release 7.7 runs.

And this is our Linux distribution:


It seems that a colleague of mine tried to update the java version to the latest version (jdk_linux_x64-11.0.5_10) and after that several services stopped working: it doesn't recognize any USB when we plug them in, the system reports that there is no Bluetooth antenna and no Wi-Fi adapter.

Listing all the PCI devices shows that the missing devices are actually there:

However, they are not among the loaded modules:

The system only sees the main HD and none of the pen drives plugged in:

My original idea was reinstalling the OS image and from there continue with the standard configuration of our devices. The problem is that I can't run any pen drive installation as long as the tablet doesn't recognize them.

Any ideas or suggestions on how to bring the system back to life?

Thank you in advance!!

Íñigo.
