According to it's datasheet, The ISP1562 integrates normal OHCI / EHCI compliant USB cores. My ISP1563 works fine with these CONFIGs enabled. > Please do reply Please don't push anybody.

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.

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 clear my query sir (-: 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.
