docker container give usb access
To give a Docker container USB access in C, you can use the libusb library. Here is an example code snippet:
#include <stdio.h>
#include <libusb-1.0/libusb.h>
int main() {
libusb_context *context = NULL;
libusb_device_handle *handle = NULL;
// Initialize libusb
if (libusb_init(&context) != 0) {
printf("Failed to initialize libusb\n");
return 1;
}
// Open the USB device
handle = libusb_open_device_with_vid_pid(NULL, VENDOR_ID, PRODUCT_ID);
if (handle == NULL) {
printf("Failed to open USB device\n");
libusb_exit(context);
return 1;
}
// Perform USB operations here...
// Close the USB device and exit
libusb_close(handle);
libusb_exit(context);
return 0;
}
Replace VENDOR_ID
and PRODUCT_ID
with the appropriate values for your USB device. You can find these values using the lsusb
command in Linux or macOS.
Make sure to link against the libusb library by adding -lusb-1.0
to your compile command.
