Hi all, I am trying to use a Cherry USB Keyboard (with ID card reader... of course I don't need the reader with P9 but it's the USB keyboard I have at hand) with P9 in the Raspberry.
The keyboard works just fine with all other Raspberry OSes I have tried (Raspbian, RaspBMC and IIRC, I also tried with RISC OS once.) But with Plan9 it doesn't work at all. If I have it plugged from start the system won't boot (halts when starting the USB devices and hangs there) and if I plug it after bootup, it does nothing at all (not even error logging in the error window.) I have tried this same keyboard under qemu's Plan9 (under Mac OS host) and it works without problems. I'm not sure if Mac OS serves the USB device "as is" and then Plan9 has to use its driver to use it (which would mean the keyboard is OK for Plan9) or Mac OS hides the device behind a generic USB keyboard to show to the virtual machine. So I'm not sure if (for some reason) Plan9 can't use it because it doesn't work under Plan9 (except for the card reader, it is a standard USB keyboard, nothing fancy,) if Plan9 draws more energy from the Raspberry (go figure) and makes the keyboard unavailable (doesn't make much sense, since I can plug the keyboard and an USB mouse at the same time with all other operating systems.) Any ideas? Regards, Ruben Berenguel
