When I try to read an 8gb SDHC card from my digital camera, odd things happen.
First, Kubuntu detected the card. I could use krusader to open it and go down into /media/EOS-DIGITAL/DCIM/100_CANON and list the files. But when I started to copy them to my hard disk, it suddenly said the DCIM directory did not exist.
I rebooted and things got worse. Now it does not seem to detect the card at all. Dmesg tells me, among other things,
[ 442.194346] NVRM: os_raise_smp_barrier(), invalid context!
[ 442.210803] NVRM: os_raise_smp_barrier(), invalid context!
[ 443.711275] usb 1-2: new high speed USB device using ehci_hcd and address 8
[ 443.840034] usb 1-2: device descriptor read/64, error -71
[ 444.081275] usb 1-2: device descriptor read/64, error -71
I have no idea what that means. I have found some related things on the Internet, but too complicated for my little brain.
What to do?
