Having struggled to make my USB Zip 100 drive to work on my Toshiba Laptop, I wonder whether the problem is in my controller (NEC) which appears to need a usb-ohci driver (/sbin/lspci --v). When I was using the kernel 2.2.14, the controller was not recognised at all. The laptop worked well otherwise. When I upgraded to the Red Hat linux distribution version 7.0, I had a kernel 2.2.16 up and running. At my first re-boot after the new kernel was on, kudzu (I thikn it was kudzu) said that a new hardware was found and asked me to confiure it. Yes, I said. My problems then began. When I turn my laptop on, a significant number of times the system hangs when initialising the ohci controller, or if it passes this stage, it freezes when mounting the usb filesystem. Trying a few times generally works, in the end. Support for usb-storage (needed by the Iomega ZIp USB 100) was not included in this kernel 2.2.16, so I have compiled my newset kernel 2.4.2 with built-in scsi disk support, usb-ohci and usb-storage as modules. I have had care to upgrade to the most recent modutils and hotplug, plus some more requirements reported in source/Documentation/Changes. Now booting with kernel 2.4.2 also produces hang-ups, this time they can also be when hotplugging starts or also when checking for new hardware. The system freezes and there remains the only option to re-boot. I am beginning to think that my usb-ochi driven NEC controller is not happy to talk to the usb-ohci driver, as this comes with kernel 2.4.2. I need to use this laptop in a secure and stable way, so may be my priority now is to exclude the initialisation of the usb controller, though it's very sad considering all the time I have invested (plus the money that I have spent to get the USB Zip drive). Could anynone please recommend a document to read on how to mange the hardware to be supported at start-up? In addition, is there anything that I can do to understand whether my NEC usb-controller is `well driven' by usb-ohci? May be I should change some lines in usb-ochi.c ?
