Greetings:
I am trying to get a generic cardbus based USB 2.0 card working with an
external USB hard drive. Even though I have received some good help to date,
things are still not going well.
The original problem was that inserting the cardbus card into my laptop would
cause the entire PCMCIA system to die instantly. This problem is fixed -
inserting the card no longer kills the PCMCIA system.
What appears to be happening now is that there are codepath problems in the
EHCI/UHCI/OHCI code as they relate to the SCSI Disk driver. All this is
tested against 2.6.11.6 on a Slackware 9.1 based laptop.
The USB drive works perfectly (albiet very slowly) when plugged directly into
the laptop's USB 1.1 port.
When the USB drive is plugged into the USB 2.0 cardbus card, the drive is ID'd
correctly (make/model), but the driver can not read the partition table.
Attempting to mount the drive doesn't work. Unplugging the USB drive causes
the lockup to unlock.
Plugging a USB keydrive into the USB 2.0 card causes no problems. Drive is
ID'd, make/model read, partition table read, can read/write/mount the key
drive without issue. Same when plugging the keydrive into the laptop's
USB1.1 port.
Laptop is an HP Pavilion N5150, Intel USB chipset (UHCI). Cardbus card is
generic ALI based USB chipset (EHCI/OHCI). USB drive is a Sony VAIO external
case for a 2.5" drive. The chip in the usb drive has no manufacturer
markings on it, just the following character sequences: CS881BAG, 0451B0C104,
107
HELP!!!!

I've got an external 2.5" VAIO case (VAIO original yeah, right) that
works ok what I can tell with USB2 on my laptop. Are the id:s below
the same as yours?

E: Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
The 2.5" case also works with USB 1.1, but it is kind of funky. I
guess it requires lots of power. So much power that I have to use a
hub with external power to connect it to a winxp laptop. Connecting it
directly to the laptop does not work for some strange reason - MANY
other devices are powered directly from that laptop.
I recently realized that there are no firewire pccards on the market
today that can power my firewire-powered cd-burner without using an
external ac adapter. My Apple G4 Mac can power the darn thing over
firewire though. Maybe the same thing goes for USB2 host controllers
on pccard? Maybe you need an external ac adapter?

Looks like we have basically the same device.
> on pccard? Maybe you need an external ac adapter?
This would be remotely possible but I would discount it being probable. You
see, a drive requires the most power at spin up. This thing spins up just
fine regardless of what port I have it plugged into. On top of that, the USB
card has a power adaptor already (plugs into the laptop's USB port) that I
always use.
Besides, how would I connect an external power supply to this? No connector
on the drive assembly...

Ok, I have eliminated power as a possibility by routing the secondary USB
connector for the drive to a powered USB hub. No difference, the drive still
spins up, and the system still can not read the partition table (the drive is
known to have a good EXT3 partition on it).
Here are the specifics on the USB card I am using from dmesg:

I have a similar problem.
I have a HP NC6000. It uses the Yenta PCMCIA kernel driver.
If I insert a PCMCIA card that uses cardmgr, it all works fine.
If I insert a Cardbus PCMCIA card it instead shows up as a PCI card, and
cardmgr does not even see it.
Now, here is the real problem. I can activate the card, and read PCI
information from it, but as soon as I do something like this:
value = inb(port);
I.e. The first inb/inw/inl command that the driver tries to do, locks up
the PC.
Does anyone have any ideas how to fix this?
