Hi, I have a BeagleBone Black and want to attach a number of numpads via USB. Unfortunately it is not possible to connect more than 5 USB numpads. It seems like a kernel or device driver limitation since the bus topology does not matter. The sixth numpad always produces the following (/var/log/syslog):
input: USB Keyboard as > /devices/ocp.3/47400000.usb/musb-hdrc.1.auto/usb1/1-1/1-1.4/1-1.4.1/1-1.4.1:1.1/input/input40 input: failed to attach handler kbd to device input40, error: -16 hid-generic 0003:1241:1503.0028: input,hidraw11: USB HID v1.10 Device [ > USB Keyboard] on usb-musb-hdrc.1.auto-1.4.1/input1 I've connected a powered 4 port Hub with another unpowered 4 port hub but have tried several other topologies. Maybe someone knows what the problem is or knows what the obscure error number 16 stands for. Thanks in advance.
