usb controller dies mounting external usb hard disk
 

Help !

I got a maxtor One Touch II external USB drive. It works just fine under FC3. I installed FC4 on an old box and I try to get this disk to work on this machine now.
kernel is 2.6.13-1.1532_FC4 #1

the usb ports are detected just fine :
I turn on the external disk (or I plug it in - it amounts to the same problem) :

But when I try to mount the disk :

The usb controller is on board - so I think it cannot be a PCI problem.
Anyway, I got myself a extra USB controller card (D-LINK DUB-A2) and I disabled the on board controller in the BIOS. The results are exactly the same.
Strangely enought, I can fdisk /dev/sda and view the partition table. I tried several times to repartition the disk (on my working FC3) and reformatting the drive, using all kinds of file systems.

When I do :
then the controller is back up and I can fdisk the drive again but mount still hangs the usb controller.
This is the output of /proc/bus/usb/devices

Any wizards out there ??

thx in advance

I don't really have a good conclusion but here is a few things I see. You are using the uhci-hcd module for the orginal USB onboard controller. That is used for some version 1.0-1.1 usb controllers. Other 1.0-1.1 controllers use ohci-hcd module. For 2.0 USB controllers you use ehci-hcd module. So if on board usb is disabled and the dlink controller is plugged then just use ehci-hcd module, since my search shows that controller is a 2.0 usb controller.

Output of /proc/bus/usb/devices is showing a 12mb devices. If it was seeing the dlink 2.0 it should say 480mb. I would turn on the onboard usb controller and still have the dlink controller plugged in and see if the /proc/bus/usb/devices differ as far as addition devices. If there is no difference then the dlink card is not plugged in or is not compatiable with any of the USB modules.

Never used that controller and don't know if it is good or bad. Does it work with other USB devices?

My only experience with pci USB 2.0 controllers are those from Adaptec. Never had a problem with my setup.

Hope something helps.

It's somewhat working....
 

Many thx Brian for your interest and help.

I re-partitioned the drive and reformatted the partitions on it.
Still I have the onboard controller disabled and I moved the new USB D-LINK controller to a different PCI slot.
And wow, I can mount it and touch /mnt/maxtor/test.txt actually put a file on it ! Victory.

However the system is now soooooooo slow that I couldnt get a reply posted here and had to switch pc's.
The display refreshes now so slow that I would wait 5 mins for a typed text to appear. Maybe I have some kind of interrupt conflict ?

Did I mention that my bios is <2000 and that ACPI is disabled for this reason. Can this be related to this ?
And another question, I can see 4 ports in the /proc/bus/usb/devices, but the D-LINK only has 2. I'm guessing the onboard controller isnt really disabled then ?

Anyway, happy to make some progress here.

Can not say its an interrupt issue or not. Since moving from on pci slot to another it could be. So if the card is not in the machine, everything works great minus the 2.0 drive? My only other thought is try a different brand of USB controller.

Hope you get it going

must be some IRQ problem
 

after a while this appears in de logs, and the device dies....
