It seems that this bug is now present in the previous Ubuntu version. As I said in my previous comment, my card reader that used to work with kernel 2.6.15-27 does not work anymore with 2.6.15-28 on Dapper.
I can make it work by unloading the ehci module. It really seems to be the same problem. The dmesg error messages are very similar too. -- USB devices are not recognized when having ehci_hcd modprobed https://bugs.launchpad.net/bugs/88746 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
