@Andy Rabagliati: Absolutely. I have had that bug / regression before. It most certainly is a mounting problem. It _may_ indeed be related to whatever underlying chipset Alcor is using as I suspect the Alcor is ultimately just junk. What would be interesting is to somehow get a feeling for what underlying hardware is being used at the chipset level in these devices.
I'd suggest you track down the appropriate bug report and report if necessary. It might be wise to reference this bug report as I find it suspect that your card reader also happens to be an Alcor. I did a further test with the digital SLR camera itself and it mounts fine and transfers files 100% properly and speedily with _no_ problems. This gives further credibility to the notion that the crashing of ehci_hcd is directly related to particular hardware of the actual devices -- not the host bus controller / combination. I'd certainly be willing to flag Alcor as a hideous vendor (included in nGear, NMedia, and other models.) If David Becker's bug is related as it appears to be (https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.20/+bug/88746/comments/409) it would seem that we could add Kingston to that list at least in one instance. What we somehow need to do is: 1) Identify exactly what underlying hardware is the source of the problem in the devices. 2) Provide a way for people who are stuck with onboard card readers of the hardware to have the 'echo "128" >' command automatically done every boot for them. 3) Figure out who we need to contact regarding the bug. Greg Kroah-Hartman suggests at the end of http://bugzilla.kernel.org/show_bug.cgi?id=ehci_hcd to file it to the linux-usb list. I'm not entirely sure that it belongs there though? Good detective work folks. I think we need someone to help us figure out the lower level stuffs on the devices somewhere? Perhaps the only way is through documentation? Is there a way to read more deeply into the device's ancestry? -- 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
