After quite a but of hunting and messing around, I found out the source of at least my problem.
I have a Sony Vaio SZ2XP using a VSP-MCA20 express card to read SD cards. This card reader does not read SDHC cards, and searches on various Sony websites leads me to believe that it never will. It also seems that my other card readers also do not handle SDHC cards either. I'll probably go and buy a newer card reader and most likely buy a Dell for my next laptop. -- ehci_hcd module causes I/O errors in USB 2.0 devices https://bugs.launchpad.net/bugs/88746 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
