Hi anyone,
for some reason I can't get the string descriptor of an device:
# ...
for device in devices:
if device.iManufacturer > 0:
string = usb.util.get_string(device, 254, device.iManufacturer)
print "string:", string
else:
print "no descriptor"
My backend is the latest libusbx-1.0.14-win.
I get a similar error when I'm using C directly:
unsigned char *data = malloc(30);
ret = libusb_get_string_descriptor_ascii(handle, desc.iManufacturer, data, 29);
if (ret < 0) {
const char *error = libusb_error_name(ret);
printf("ERROR in retrieving string descriptor: %s\n", error);
exit(1);
}
The error message:
"ERROR in retrieving string descriptor: LIBUSB_ERROR_NO_MEM"
Might this be a bug in libusbx?
Best regards
Stefano
