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!!
