To: [EMAIL PROTECTED] I would need a way to determine which of my USB ports are actual native ports and which are internal USB hub ports. How can I achieve that easily?
The reason being is, that I want to investigate a theory to this bug: --- Certain USB devices do not work properly, or do not work at all, while the ehci_hcd module is loaded. A solution is to unload the ehci_hcd module, which is loaded every time the computer starts, using the command 'sudo modprobe -r ehci_hcd'. This works fine but unfortunatly ehci-hcd is necessary for using USB 2.0, so you lose USB 2.0 features. Get more info at https://bugs.launchpad.net/bugs/88746 --- This bug is bugging me for about a year now. However, this bug is not showing up on all my USB ports. As this problem has be reported to show up particularly on USB Hubs, I suspect it might only show up on those of my USB ports that are actually internal USB Hub ports. I would like to verify that theory but would need advice on how to do that. Maybe somebody could also have a look at the bug report mentioned. This bug has been reported beginning of this year in the Ubuntu bug tracker. Up till now, it does not seem like anybody has laid hand on it yet. I also have no idea if this bug report even made it upstream. Does Ubuntu/Launchpad have a facility to escalate bugs to the kernel bug tracker? I am somehow loosing faith in the whole Launchpad approach. Maybe you could advise if I should rather report kernel specific bugs directly to the kernel bug tracker instead of hoping the Ubuntu guys will take care of channeling it upstream.
