The title is fairly self-explanatory. This bug was produced on a Dell Inspiron 600m. Without uhci_hcd, power is not supplied to usb devices, and only one bus is shown, which is inaccessable. lsusb without uhci_hcd: b-triangle ~ # lsusb Bus 001 Device 001: ID 0000:0000 lsusb with uhci_hcd: b-triangle ~ # lsusb Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 001 Device 001: ID 0000:0000 lspci dump: b-triangle ~ # lspci 00:00.0 Host bridge: Intel Corporation 82855PM Processor to I/O Controller (rev 03) 00:01.0 PCI bridge: Intel Corporation 82855PM Processor to AGP Controller (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 81) 00:1f.0 ISA bridge: Intel Corporation 82801DBM (ICH4-M) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801DBM (ICH4-M) IDE Controller (rev 01) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01) 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R250 Lf [FireGL 9000] (rev 02) 02:01.0 CardBus bridge: O2 Micro, Inc.

Reopen with udev version and kernel .config
Created attachment 91494 [details] .config file for affected system
And, it ditched my comment. [ebuild R ] sys-fs/udev-087-r1 0 kB
Why would this version of udev "coldplug" a PCI device like this? It never has in the past :) If you want this kind of functionality, please upgrade to the latest unstable version of udev.
