USB SD card reader does not appear although detected when using lsusb command
by grumpyskeptic from LinuxQuestions.org on (#5QWGD)
Using Linux Mint 20.2 Cinnamon, Dell Inspiron 531.
When I put a USB card reader into a USB slot, nothing appears either on the desktop or in the file manager Nemo.
But when I use the command lsusb, it gives this result:
Bus 001 Device 010: ID 0000:0000 ENE UB6225
I get exactly the same results regardless of the SDHC card being in the reader or not.
Is there any way to activate it?
Thanks.
Update: I've found the verbose mode lsusb -v and the result is:
(It says "Couldn't open device, some information will be missing" for every device).

The dmesg command produces pages and pages of output, mentions UB6225 seven or eight times perhaps because I have been pulling it in and out of the sockets,. The final part is:
