I am looking for assistance on how to resolve an issue with getting the Keyspan USA-19Qi USB to serial port adaptor to work with a vanilla build of Redhat 7.3. I noticed in the error log that the USA-19Qi is registered without firmware and am concerned this is causing the problem. Steps taken so far are: 1. Download the driver files from the keyspan web site 2. Copy these files to /usr/src/linux-2.4/drivers/usb/serial 3. cd /usr/src/linux-2.4 4. copy the generic config from configs/kernel-2.4.18-i686.config to .config 5. run make xconfig and turn on the firmware in the USB->SERIAL CONVERTER section 6. make depend clean bzImage modules modules_install 7. Copy arch/i386/bzimage and System.map to /boot 8. update grub 9 reboot The system boots ok, but when the USA-19Qi is plugged in, the following error is logged in /var/log/messsages and the USB subsystem no-longer functions.
