Hi,
I have the strange problem, that when I'm using pyUSB with libusbx as backend I
get the error "Insufficient memory".
I tried to use then libusbx directly and it end up in an similar error:
"ERROR in retrieving string descriptor: LIBUSB_ERROR_NO_MEM"
I have extended listdev.c:
// ...
char data[50];
ret = libusb_get_string_descriptor_ascii(handle, desc.iManufacturer, (unsigned
char*) data, 29);
if (ret < 0) {
const char *error = libusb_error_name (ret);
printf("ERROR in retrieving string descriptor: %s\n", error);
exit(1);
}
I get an similar error when I'm using xusb.c:
Reading string descriptors:
libusbx: warning [auto_claim] program assertion failed - autoclaim_count was
nonzero
libusbx: warning [auto_claim] program assertion failed - autoclaim_count was
nonzero
I'm using the dll of libusbx-1.0.14 for Windows.
Any ideas?
Best regards
Stefano
