According to it's datasheet, The ISP1562 integrates normal OHCI / EHCI
compliant USB cores. My ISP1563 works fine with these CONFIGs enabled.

Well, that seems odd. What kind of cpu / platform / hardware are you using?
Please send the output of `lspci -vv` and `cat /proc/cpuinfo`
If you have the ISP1562 attached to PCI, I guess the interrupt assignments
are wrong or the IRQ line is broken.

Try booting the kernel with "irqpoll". Example:

 > linux noapic pci=irqroute pci=noacpi acpi=off irqpoll

Check if that helps.

Well, I just don't know.
What kernel architecture do you use? ppc or powerpc?
In case you use the former (which is deprecated),
you might want to try the latter.

(-: Please follow my advices:

1. DO NOT remove the mailing list from CC: (and the chance anybody is
    able to help you!)
2. post the output of lspci -vv.

Next step is: contact the guys in the linux-usb mailing list.
