Bug 427143

Description of problem:

I have a computer based on the nForce4 chipset, CPU is Athlon XP. I was using
Fedora 7 with all latest upgrades, then I have upgraded to Fedora 8. After this
USB storage devices inserted into the front computer panel cheased to be
recognized. I don't know why, but this affects only USB storage devices (at
least a USB Bluetooth dongle I've tried worked fine). The same USB storage
devices work fine if I insert them into a USB hub located on the rear side of
the monitor (and monitor is inserted into the rear USB connector), or into the
rear USB connector directly.

However, if I install the latest Fedora 7 kernel (kernel-2.6.23.8-34.fc7), the
USB storage devices work fine. I tried this several times, and it shows 100%
repeatability.

Version-Release number of selected component (if applicable):

2.6.23.1-42.fc8 (stock f8 kernel)
2.6.23.9-85.fc8

both kernels manifest same (incorrect) behaviour.

How reproducible:

Always

Steps to Reproduce:
1. Hmm... get a MSI Mega 180 barebone :-(
2. Insert a USB flash into the front panel

Actual results:

With kernel kernel-2.6.23.9-85.fc8 it doesn't get recognized, and kernel log says:

usb 3-3: new high speed USB device using ehci_hcd and address 5
usb 3-3: device descriptor read/64, error -71
usb 3-3: device descriptor read/64, error -71
usb 3-3: new high speed USB device using ehci_hcd and address 6
usb 3-3: device descriptor read/64, error -71
usb 3-3: device descriptor read/64, error -71
usb 3-3: new high speed USB device using ehci_hcd and address 7
usb 3-3: device not accepting address 7, error -71
usb 3-3: new high speed USB device using ehci_hcd and address 8
usb 3-3: device not accepting address 8, error -71

Expected results:

With kernel kernel-2.6.23.8-34.fc7 it shows the following in kernel log:

usb 1-3: new high speed USB device using ehci_hcd and address 5
usb 1-3: configuration #1 chosen from 1 choice
scsi3 : SCSI emulation for USB Mass Storage devices
scsi 3:0:0:0: Direct-Access              USB FLASH DRIVE  PMAP PQ: 0 ANSI: 0 CCS
...

Additional info:

The output of lsusb with the flash inserted on kernel kernel-2.6.23.8-34.fc7:

Bus 002 Device 002: ID 046d:c50b Logitech, Inc. Cordless Desktop Optical

When inserted into monitor the device shows as:

Bus 001 Device 007: ID 1005:b113 Apacer Technology, Inc. Handy Steno 2.0 (256MB)

With a f8 kernel the device doesn't show in the lsusb list when inserted into
the front USB connector. However, if I insert it into the hub located on the LCD
monitor, it works fine:

Bus 001 Device 006: ID 1005:b113 Apacer Technology, Inc. Handy Steno 2.0 (256MB)
Bus 001 Device 003: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0

It looks like the USB buses are enumerated in a different order on a f8 kernel
(are there any f8-specific USB patches?). With it, the front panel is USB bus 3,
and monitor hub is bus 1, with f7 kernel both are bus 1, and everything works fine.
