i migrate from an Pi3 to an Pi4.
After the install on an Pi4 i had difficultys to get the USB Devices working after restoring the Backup.
Finally i got it.
The Pi4 was running for 3-4 Days. Somtimes i got an freeze.
But after an reboot everthing runs well again.
After one of the freezes i had again the missing USB Device thing.
Then i descide to buy an new origiginal power supply–> still notworking
To be sure that i have no issue with the SD Card i buy a U3 Class10 High endurance–>still not working
Also a normal USB Stick is not fond under Hardware.
Any ideas how to solve the Issue?
I can not use a lot of stuff at the moment, also the shutters
Thank a lot in advance!
