bus_alloc_resouce() failure for OPTi 82C861
Hi there,
I installed -CURRENT on my old PC(ThinkPad235 aka Chandra2),
but its USB device doesn't work.
(it works on Windows environment)
[boot message]
ohci0: OPTi 82C861 (FireLink) USB controller irq 10 at device 5.0 on pci0
ohci0: Could not map memory
device_probe_and_attach: ohci0 attach returned 6
in source code, sys/pci/ohci_pci.c
rid = PCI_CBMEM;
sc-io_res = bus_alloc_resource(self, SYS_RES_MEMORY, rid,
0, ~0, 1, RF_ACTIVE);
if (!sc-io_res) {
device_printf(self, Could not map memory\n);
return ENXIO;
}
It seems the function bus_alloc_resource() returns NULL.
How can I avoid this failure?
TIA

You can't. However, you can work around it like the pccbb driver
