Oddly enough, even though the SPLIT packet's contents are now correct, the device still doesn't respond. Bizarrely, when I interpose a USB-1.1 hub between the RPi and the compound device, it _does_ work. I guess this indicates the device's embedded hub isn't quite up to snuff. But why it should work okay with a PC and not with a Raspberry Pi is beyond me. > > Can you tell me how to configure a mainline kernel to work on the > > Raspberry Pi?

No easy way to figure out why -- nothing shows up on the HDMI screen but the color splash.
