Hello,
I've the same problem in my notebook. Some time ago, when I tried to
find a solution, I realized that the uhci_interrupt() function was never
called, so I supposed it was a more generic IRQ/PCI problem and not a usb
driver problem.
Last night, playing a littel with the pci code, I found that if you put
the PCI access mode as BIOS, and in the file
linux/arch/i386/kernel/pci-pc.c in the function pcibios_enable_device()
add the line
if (dev->irq == 10) dev->irq = 0; // Being 10 the IRQ of your
// USB controller
Just before:
if (!dev->irq) {
u8 pin;
...
you force the rescaning of the PCI bus when the uhci or usb-uhci driver
register de interrupt and everything works fine.
The bad thing is that really I don't know where is the problem, neither
have time to study how the PCI support is done to find it. I just did a
quick follow of the request_irq() function.
Hope this can help to solve the problem.
Cheers.
Nacho.
PS: This should be an old problem as I've tried the usb backport in 2.2.14
and al least 5 kernels from 2.3.34 to 2.3.99-pre4
