Description Mihail Keepa 2006-11-15 13:40:01 UTC 
Most recent kernel where this bug occur: 2.6.18.2; 2.6.19-rc5; 2.6.19-rc5-mm1
Distribution: Debian GNU/Linux "etch" (4.0)
Hardware Environment: Asus A3L laptop. P-M 2.0 GHz, 1Gb RAM, Intel 852GME 
chipset, 100 Gb HDD, DVD-CDRW
Software Environment: GCC 4.1
Problem Description: when I connect my exterlan 40Gb usb drive in canyon box I 
get:

usb 4-1: new high speed USB device using ehci_hcd and address 3
usb 4-1: configuration #1 chosen from 1 choice
SCSI subsystem initialized

usb-storage: waiting for device to settle before scanning
usbcore: registered new driver usb-storage
USB Mass Storage support registered.

usb 4-1: reset high speed USB device using ehci_hcd and address 3
usb 4-1: reset high speed USB device using ehci_hcd and address 3

this "reset" block different programs to work with disk! Between two messages
past 15 - 30 sec.

Steps to reproduce: Just attach externel usb drive. If ehci_hcd is off in 
kernel configuretion all work correctly... but i haven~t got usb 2.0!

no....  What kernel did *not* have this bug?
Comment 2 Alan Stern 2006-11-16 07:07:23 UTC 
Turn on CONFIG_USB_DEBUG and CONFIG_USB_STORAGE_DEBUG and rebuild the USB
drivers.  Then attach the dmesg log showing what happens when you turn on the
drive and those resets occur.
Comment 3 Adrian Bunk 2007-02-06 20:26:38 UTC 
Please reopen this bug if:
- it is still present with kernel 2.6.20 and
- you can provide the requested information.
Comment 4 Antonio Luigi Bonfitto Junior 2007-09-11 03:56:18 UTC 
Hi... i'm using Debian on a HP Pavilion ZE4900 notebook... i've just done a dist-upgrade and a upgrade... there's nothing more to upgrade here... literally... 

ahnn... just for logging, i didn't got time to compile a kernel here... but i'll do it today.... and as soon as i get the new data log i'll put it here....


and, yes, that bug started on the kernel 2.6.18.... before that version, any functions on a usb storage device was ok....

If you want to report a bug, please open a new bug report of your own.  
Don't just add comments to somebody else's report, especially if that 
report has already been closed.
