I had a similar problem with USB devices about a year ago. Some device would be recognized if plugged into a front port and not recognized if plugged into a rear port. What I conluded was the 2.4.20 through 2.4.25 kernels I was using did not completely support my motherboard, which has an nVidia nForce2 chipset and USB controller, since switching to a 2.6 kernel fixed the problem. I am currently using a Debian kernel-image-2.6.5-1-k7. I've also tried 2.6.7-1-k7 and 2.6.8-1-k7 but have had some problems with them. If you have fairly new hardware, your current kernel drivers may not completely support it. -- Jerome
