I own a Texas Instruments TI-89 graphing calculator as well as a "Silver Link" USB cable to link it to my Red Hat 8-based computer. I am using the popular linking problem called TiLP to link the two devices together. I have no available serial ports for the older "black" links (or others like it) so I am using this USB cable instead. It has a driver that is even included with the kernel sources starting with 2.4.20. I have tried both using the available RPM files and building from the sources. Every time I try to configure the program to use the USB cable, it says "No such file or directory" and the console output (if you run it in a terminal) asks if the driver is loaded. The driver is loaded (an lsmod will confirm this), and I have read the documentation of the driver in the kernel sources to find out the major/minor numbers and what device name to use, etc. I discovered that the program looks for /dev/tiglusb0 to be a character special with a major 115 and a minor 16. I have run a 'mknod' to do this myself (and set permissions to 666) and it still gives me this same message. I have run it both as root and under my normal user account, as well. I have recently (within the past six months) switched to Red Hat 8.0 from Slackware 8.1 and I vaguely remember having this same problem and fixing it somehow. Does anyone have any ideas as to what could possibly be wrong and how I might fix it? Thank you in advance for any help you can offer.
