Hello Olav,
some news from my development. Two facts I have found:
1. Assuming that USB needs hot plug-function the kernel always needs
usermode-functions i.e. call_usermodehelper() to install dev-nodes for
USB-Mass Storage-device. In my case I have static linked isp116x-Drivers
which are registered during __init of the kernel before rootfs is available
therfore call_usermodehelper()-> /sbin/hotplug gets -1 when open a file.
Do you know a way to register isp116x-driver after rootfs is loaded?
2. I get an Interrupt from isp when isp116x_start() is initializing the chip
before HCD_RUNNING is set. In this case the base-interrupt handler
usb_hcd_irq() never serve isp116x_irq() the interrupt stays pending. I
believe it is better to set chip-setup after hcd->state = HC_RUNNING; is
installed. What do you think about that?

It was my fault: it turns out that I had put up on the
webpage the 2.6.13-rc1 version of the driver instead of the
intended 2.6.12 version. I will change the driver on the
web. Sorry about wasting your time.

The 'SCSI emulation ...' message can be issued only after
the device attachment is detected. But it is not clear
whether the attachments are detected at all. Therefore the
problem is still likely on the isp side, not the scsi.
Play with the sel15Kres setting again. Maybe just the
current setting is incorrect. Try attaching different flash
drives. Rebuild your kernel to include USB HID device
support and try whether keyboards or mice are detected. If
you have progress, please post also the new dmesg.
Olav
