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!!!!
