HP ScanJet 5300C notes.
Okay, continued research on this machine. How have people got this scanner to work under GNU/Linux? After much research and a little bit of experimentation, this is how. Open up Simple Scan on Ubuntu (or any derived distribution), of a somewhat old vintage, say 10.04 LTS, Karmic Koala, or Hardy Heron, and just do a regular 300 DPI color photograph scan, no customizations involved. Then everything will just work. But, if you make any customizations or use a newer distribution, or a distribution that is too old, then it won’t work.
Note that you will also be able to get everything to work if you run the operating system in a virtual machine and have the guest OS use the USB device exclusively.
Oh yeah, and if you do mess up the USB device and need to reset it, here’s how.

Including the source code and instructions of that program here for posterity:
/* usbreset -- send a USB port reset to a USB device */
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
#include <errno.h>
#include <sys/ioctl.h>
#include <linux/usbdevice_fs.h>
int main(int argc, char **argv)
{
const char *filename;
int fd;
int rc;
if (argc != 2) {
fprintf(stderr, "Usage: usbreset device-filename\n");
return 1;
}
filename = argv[1];
fd = open(filename, O_WRONLY);
if (fd < 0) {
perror("Error opening output file");
return 1;
}
printf("Resetting USB device %s\n", filename);
rc = ioctl(fd, USBDEVFS_RESET, 0);
if (rc < 0) {
perror("Error in ioctl");
return 1;
}
printf("Reset successful\n");
close(fd);
return 0;
}

Oh yeah, I like this quote:
Thanks for the advice. I really know nothing about computers, so I’ll wait for this to get fixed. In the meantime, I’m using my wife’s computer to scan documents, and carting them over to my machine. Sure it’s cumbersome, but it’ll work for now.
Too bad, waiting will never get it fixed!

Oh, that LundScape website was particularly interesting and useful, here I’ll include another link to it about setting up FreeNX because I saw it nearby.
