Hello
On a pretty standard PC with Intel chipset / UHCI
00:1f.2 USB Controller: Intel Corporation 82801AA USB (rev 02) (prog-if 00 [UHCI])
Subsystem: Intel Corporation 82801AA USB
Flags: bus master, medium devsel, latency 0, IRQ 11
I/O ports at 1820 [size=32]
with 2.4(.21) usb-storage worked fine. With 2.6.5 I had a hang, which I
reported on the list, but the information was not sufficient, and I was
somewhat reluctant to crash this PC too often. Now I've tried 2.6.9-rc4
and storage doesn't attach to devices at all:

USB Mass Storage support registered.
The deregister / register above is because I unloaded usb_storage,
recompiled it without CONFIG_USB_STORAGE_RW_DETECT and re-loaded.
An extract from my .config:

The distro is pretty old, I am not using any hotplug, but all necessary
modules should be loaded:
usb_storage 39424 0
uhci_hcd 30028 0
usbcore 114180 4 usb_storage,uhci_hcd
scsi_transport_spi 11616 0
sg 30720 0
sd_mod 12560 0
scsi_mod 104428 4 usb_storage,scsi_transport_spi,sg,sd_mod
pcspkr 3080 0
i2c_i810 3876 0
i2c_algo_bit 8904 1 i2c_i810
i2c_isa 1600 0
i2c_i801 7116 0
i2c_dev 7616 0
i2c_sensor 2912 0
i2c_core 19888 5 i2c_algo_bit,i2c_isa,i2c_i801,i2c_dev,i2c_sensor
Am I missing something simple? I could try acpi=off, but it looks like the
interrupt is fine, otherwise devices wouldn't be configured at all.
Thanks
