Linux USB printer.c update for older kernels

Using ptal-mlcd with USB under Linux requires a minimum kernel version of 2.2.19 or 2.4.2, and some models require a minimum of 2.4.19pre5 or 2.5.7. If you use an older USB-capable kernel, you will need to update /usr/src/linux/drivers/usb/printer.c so ptal-mlcd will work properly.

You will need the updated printer.c, Makefile, and README file from here. (You don't need this if you're running kernel 2.4.19 or later.)

uhci patch for stock Linux 2.4.18 kernel

The "uhci" host controller driver in the stock Linux kernel 2.4.18 is broken. The 2.4.18 kernels provided with Mandrake 8.2 and RedHat 7.3 already contain the necessary fix. Other users may download and apply ("patch <linux-2.4.17-rc4-usb-je-uhci-update.patch") this patch to the "linux-2.4.18/drivers/usb" directory, then rebuild the kernel.
