I have a a multi card reader. Today accidentally I ejected my reader while formatting a SD card by Gparted. When I inserted it again, it detected is lsusb but nothing was opening ie. as a storage device.
I tried inserting SD card in laptop SD card reader and it worked fine. But with the card reader I was unable to see anything. I tried googling with several links and suggestion which says kernel compiling and all but nothing helped. I tried to open it via Gparted but it kept on searching partitions and after a long time it showed my internal hard disk only
This is lsusb result
Bus 001 Device 009: ID 05e3:0751 Genesys Logic, Inc.
This is lsusb -v result for that device

Couldn't open device, some information will be missing

Is there any remedy available to make that card reader work?
lsblk
andsudo dmesg | tail -n 20
. Include the output in your question. This will hopefully tell us more about what the kernel is doing with the storage medium in the background.
