Hi all,
I'm trying to connect an external HD with USB 2.0 interface to
a notebook with USB 1.1 interface.
Here is the scenario:
I have an old Acer TM 347T running:
---
[EMAIL PROTECTED] ~]# uname -a
Linux micro 2.6.9-55.0.12.EL #1 Fri Nov 2 10:57:39 EDT 2007 i686 i686
i386 GNU/Linux
[EMAIL PROTECTED] ~]# cat /etc/redhat-release
CentOS release 4.5 (Final)
---
with:
---
[EMAIL PROTECTED] ~]# lspci -v | grep -i usb
00:14.0 USB Controller: ALi Corporation USB 1.1 Controller (rev 03)
(prog-if 10 [OHCI])
---
The external HD is a LaCie 160GB with an USB 2.0 interface.
Now, if I boot the machine with the HD already on I get:
---
[EMAIL PROTECTED] ~]# dmesg | grep usb
usbcore: registered new driver usbfs
usbcore: registered new driver hub
usbcore: registered new driver hiddev
usbcore: registered new driver usbhid

usb 1-1: new full speed USB device using address 3
usb 1-1: control timeout on ep0in
usb 1-1: device not accepting address 3, error -110
---
If, instead, I turn the HD on after the system has already booted, I get:
---
[EMAIL PROTECTED] ~]# dmesg

More, If I am fast enough to execute lsusb before usb error, I get:
---

Finally,
---
[EMAIL PROTECTED] ~]# cat /proc/interrupts | grep ohci
10: 217 XT-PIC ohci_hcd
---
What I've already tested so far:
1) Same machine, same HD and same cable works well with Windows XP,
2) modprobe -r ohci_hcd and modprobe ohci_hcd returns the same error
as if I was booting the machine with the hard drive already on
3) noacpi as boot option of the kernel
Any suggestion will be greatly appreciated.
Dario
