Hello all, I am trying to understand a laptop with 4 USB ports, apparently identical, but all 4 work under windows and only 2 under F8. If I look in 'hwbrowser' I see 3 controllers, (2 UHCI and 1 EHCI I think) but no 'USB UHCI #n' entries like I expect. cat /proc/bus/usb/devices shows up 3 controllers, and the USB mouse I have plugged in. It ALSO shows a device "0baa 0158", which is somehow a Realtek disk (I don't think there IS one) but not "0bda 8187" (or is it 8189) that I think the wireless card should be registered as. Can anyone suggest how to debug this? Thank you, Bill Nb ACPI=off, NOAPIC were needed at boot time... -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
