PCMCIA Cardbus 2.0 cannot work

Hi all,

I juz got a generic USB 2.0 Cardbus PCMCIA card (no brand, made in China) and trying to make it work with my Iomega Predator 3 (external CD writer) . I am running Mandrake Linux 9.0 (kernel 2.4.19-16mdk) and using the pcmcia_cs-3.2.0-3mdk package. My motherboard already has a built-in USB (1.0) port.

The PCMCIA card and the Predator are recognized by WinXP as :

Code:

NEC PCI to USB Enhanced Host Controller 
+- USB 2.0 Root Hub Device 
     +- USB Mass Storage Device 
          +- IOMEGA CDRW1920ET2-B USB Device 

NEC PCI to USB Open Host Controller 
+- USB Root Hub 

NEC PCI to USB Open Host Controller 
+- USB Root Hub

I have to remove the card during boot time because it would cause the system to freeze, but it is detected when hotplugged. The following modules are loaded : ds, yenta_socket, pcmcia_core, ehci-hcd, usb-ohci, usbcore.

Checking /proc/interrupts shows :

Code:

9:     5     XT-PIC    Ricoh Co Ltd RL5c476II, Ricoh Co Ltd RL5c476II (#2), ehci-hcd, usb-ohci, usb-ohci 

11:   37     XT-PIC    usb-uhci             (for the built-in USB 1.0)

I thought that the card is working properly. Further checking shows :

# cardctl config

Code:

 
Socket 0 : not configured 
Socket 1 : 
   Vcc 3.3V Vpp 3.3V Vpp2 3.3V 
   interface type is "cardbus" 
   irq 9 [exclusive] [level] 
   function 0: 
   function 1: 
   function 2:

At this stage I tried to connect the Predator drive. Previously it was connected to the built-in USB 1.0 port. The following modules were loaded to make it work : sr_mod, scsi_mod, usb-storage, usb-uhci.

# usbview

Code:

 
+- USB OHCI Root Hub 
+- USB OHCI Root Hub 
+- PCI device 1033:00e0 
+- USB UHCI Root Hub 
     +- USB CDRW23042EXTB

and

# lsusb

Code:

 
Bus 004 Device 001: ID 0000:0000 
Bus 003 Device 001: ID 0000:0000 
Bus 002 Device 001: ID 0000:0000 
Bus 001 Device 001: ID 0000:0000 
Bus 001 Device 002: ID 059b:005a Iomega Corp.

But the device failed to be recognized when hotplugged to the USB2.0 port (PCMCIA) . Monitoring using usbview program shows :

Code:

 
+- USB OHCI Root Hub 
+- USB OHCI Root Hub 
+- PCI Device 1033:00e0 
   +- Unknown device 
+- USB UHCI Root Hub

The "unknown device" would appear for a couple of seconds then disappears.

Similarly doing

# lsusb
repeatedly while hotplugging the device shows the additional line :

Code:

 
cannot open /proc/bus/usb/002/0xx

then it disappears too.

Well, I am stumped. Any help or suggestion would be welcomed. Thanx
