Yes, it's internal hardware(bluetooth module and uvc camera). They are working. > and you may try 'rmmod ath9k' to see if new devices can be recognized on usb3. I've tried that. But it doesn't help. I see, that there are interrupts on ehci_hcd:usb3 during bluetooth activity. I also see, that numers in line ehci_hcd:usb4 are not changing at all. > Or if you can build kernel by yourself, you can enable 'CONFIG_USB_DEBUG' & 'CONFIG_DEBUG_DRIVER' and post out 'dmesg' info. I'll try to do that, but it will take some time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1172908 Title: USB 2.0 Ports Dont Work on Sony Vaio Laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1172908/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
