Hi people,

I am trying to make my two USB peripherals : Iomega Zip 100 USB and Iomega Predator 3 to work in RedHat 8.0 through a Cardbus PCMCIA USB 2.0 card. It is a no-brand one so I don't known which company manufactured it, but it is based on the NEC chip. My motherboard also has one built-in USB port. it is working using the uhci module.

I am using kernel 2.5.46 with support for USB and hotplug, while ehci, uhci, ohci, usb-storage, scsi generic, scsi cdrom were compiled as modules. I have installed the pcmcia-cs 3.2.3 packages, and when I slot in the Cardbus, the appropriate modules were automatically loaded (yenta_socket, pcmcia_core, ehci_hcd and usb_ohci).

Now, no matter what I do, I can't get any device that I connect to any USB port (either the Cardbus ones or the mobo one) to be recognized by the kernel when checking either through lsusb and usbview. I have checked through lspci, /proc/interrupts and /proc/ioports but cant find any conflict in the resource allocation. Coldplugging or hotplugging the device again doesn't help either.

Is there any step that I miss here? Any help would be appreciated ...

Hi,

Try to install hotplug:

http://linux-hotplug.sourceforge.net/

It detects usb devices and can mount too ...

.. but anyway I've got a new PC with built-in USB 2.0 and everything works fine afterwards. Suspect the problem last time was due to unsupported cardbus.
