both computers are running debian, computer A uses debian bookworm and computer B uses debain bullseye.
I tried with lsusb in computer A and it’s recognized, same brand usb sticks in A computer can’t be unmount. A and B use Mate desktop.
In computer B they can be used, no error shown in B computer.
I try to unmount-extract from A and says for hours (or forever, never tried to wait more than 2 hours) that is writing data on it. If I take out the usb memory from the usb slot in computer A, can’t be read anymore in that computer, can’t be read neither in B, but can be formated, in computer A can’t be formated.
After formating the usb in B computer, computer A doesn’t read them anymore but computer B does.
No idea what else to try
