Hi,
Happy new year for everyone :)
I have a strange problem with libusbx 1.0.14 on windows 7
when i run this test :
status = libusb_init(&ctx);
libusb_get_device_list(ctx,&list_devices);
libusb_open(libusb_dev[dev_index], &handle);
libusb_close(handle);
libusb_open(libusb_dev[dev_index], &handle);
Here the libusb_open return -3 and debug messages is :
libusbx: error [winusbx_open] could not open device
\\.\USB#VID_0525&PID_A4A0#1_00000000#{A5DCBF10-6530-11D2-901F-00C04FB951ED}
(interface 0): [5] Access Denied
then i tried this test :
status = libusb_init(&ctx);
libusb_get_device_list(ctx,&list_devices);
libusb_open(libusb_dev[dev_index], &handle);
libusb_free_device_list(libusb_dev, 1);
libusb_close(handle);
libusb_exit(ctx);
status = libusb_init(&ctx);
libusb_get_device_list(ctx,&list_devices);
libusb_open(libusb_dev[dev_index], &handle);
ThenI have the same problem !
May be we cannot open close the same device many time on the same application.
Is this normal ?
Regards,
Mohamed
