PCMCIA and New External HD

Thu Nov 16 10:11:29 EST 2006

Hi all,

I bought recently an external Western Digital HD, and formatted it with ext3.
Noticed that I didn't have USB2 ports in my laptop and transfers were
really slow. So I bought a Sitecom USB2.0 PCcard which brings 2 USB2
ports.

My kernel is 2.6.18-gentoo-r2. I installed pcmciautils and
pcmcia-cs-cis. Enabled yenta and O2Micro initialization.
I connect my PCCard and everything just works:
lspci:
 - Native USB:
00:1d.0 USB Controller: Intel Corporation 82801CA/CAM USB (Hub #1) (rev 02)
00:1d.2 USB Controller: Intel Corporation 82801CA/CAM USB (Hub #3) (rev 02)

 - PCCard:
02:0a.0 CardBus bridge: O2 Micro, Inc. OZ6933/711E1
CardBus/SmartCardBus Controller (rev 02)
02:0a.1 CardBus bridge: O2 Micro, Inc. OZ6933/711E1
CardBus/SmartCardBus Controller (rev 02)

 - NewUSB from PCCard:
03:00.0 USB Controller: NEC Corporation USB (rev 43)
03:00.1 USB Controller: NEC Corporation USB (rev 43)
03:00.2 USB Controller: NEC Corporation USB 2.0 (rev 04)

(one wierd thing here is that it should be 2 USB2.0 and not 2 USB1 and 1 USB2)

>From dmesg:

This is the card I got:

In /sys/bus/usb/devices:

So everything seems more or less ok. (for some reason mor 3 ports were
installed (2 USB1 and 1 USB2) but this card only has 2 USB2 ports.

If I connect my HD to a native port USB1.1 port:
Nov 16 13:07:28 euler hub 1-0:1.0: over-current change on port 2
Nov 16 13:07:33 euler usb 1-2: new full speed USB device using

Nov 16 13:12:48 euler usb-storage: *** thread awakened.
Nov 16 13:12:48 euler usb-storage: -- exiting

However, if I connect it to one of my new USB2 ports the HD starts to
click. Yeah, there's a clicking sound in it and nothing happens,
nothing is shown in dmesg.

Any ideas of what can I do? Or what the problem might be?
