I suffer from the same application hang with usb devices that others seem to have encountered too. USB devices work fine after bootup, but after the system has been up a while any application accessing a usb device hangs. The program does not respond anymore and ps lists its state as DW. The device is completely hung up at this point, and refuses to work until a reboot. This problem came with the 2.6.6 kernel version (the only 2.6.x series kernel I've run on this machine). In 2.4.x it works fine.
Then I tried with the usbfs unmounted. The problem doesn't occur anymore. No matter how many days the system stays up, or how many times the device is accessed by a program, it continues to work as normal. This almost a vanilla 2.6.6 kernel. Only a lirc patch is applied.
