since this is such a short list, here's the output from my kernel
scanning script that ran through the drivers/usb directory, looking
for preprocessor tests of CONFIG variables that don't exist, with a
lost of all files *throughout* the entire tree that refer to them:
>>>>> ARCH_KARO
drivers/usb/host/isp1362.h:11:#if defined(CONFIG_ARCH_KARO)
include/asm-arm/mach-types.h:4388:#ifdef CONFIG_ARCH_KARO
arch/arm/tools/mach-types:207:karo ARCH_KARO KARO 190
>>>>> CPU_PXA27x
drivers/usb/host/ohci-pxa27x.c:206:#ifdef CONFIG_CPU_PXA27x
drivers/usb/gadget/pxa27x_udc.c:2564:#ifdef CONFIG_CPU_PXA27x
>>>>> MACH_OMAP_H4_OTG
arch/arm/mach-omap2/board-h4.c:280:#ifdef CONFIG_MACH_OMAP_H4_OTG
drivers/usb/gadget/omap_udc.c:2097:#ifndef CONFIG_MACH_OMAP_H4_OTG
drivers/usb/gadget/Kconfig:193: select ISP1301_OMAP if MACH_OMAP_H2 || MACH_OMAP_H3 || MACH_OMAP_H4_OTG
>>>>> USB_LANGWELL_OTG
drivers/usb/gadget/langwell_udc.c:24:#if defined(CONFIG_USB_LANGWELL_OTG)
drivers/usb/gadget/langwell_udc.h:22:#if defined(CONFIG_USB_LANGWELL_OTG)
as in, for example, there's a file testing for CONFIG_ARCH_KARO when
there is no Kconfig file that defines the config variable ARCH_KARO.
you get the idea.
