I am trying to get nqc 3.1 r1 working on my Slackware 9.1 box using Linux
kernel 2.6.11.2. When I plug the IR Tower into my USB port, it's recognized.
This is what I get from dmesg:
hub 2-0:1.0: state 5 ports 3 chg 0000 evt 0002
ohci_hcd 0000:00:01.3: GetStatus roothub.portstatus [0] = 0x00010301 CSC LSDA

usb 2-1: configuration #1 chosen from 4 choices
usb 2-1: adding 2-1:1.0 (config #1, interface 0)
usb 2-1:1.0: hotplug
but when I try to send data to the rcx, this is what happens:
# nqc -v -raw 120001 -S /dev/usb/lego0
Problem talking to IR device
Tx: 55 ff 00 10 ef 10 ef

Retrying...
Tx: 55 ff 00 10 ef 10 ef
Rx:
yes, the rcx is turned on, and facing the tower.
Anyone have any ideas?

| Hi David, (...) these are the log messages from the USB core, but I don't see any from the driver, are you sure the driver is loaded? Also, the device nowadays is supposed to be at /dev/usb/legousbtower0. If you use udev it should create that (...) (20 years ago, 17-Mar-05, to lugnet.robotics.rcx)
