This always fails:
char devname[256];
if (libusb20_dev_get_iface_desc(pdev, n, devname,
sizeof(devname))) break;
while this works:
char devname[128];
if (libusb20_dev_get_iface_desc(pdev, n, devname,
sizeof(devname))) break;
Because this function takes a uint8_t for length:
<libusb20_ugen20.c:851>:
static int
ugen20_dev_get_iface_desc(struct libusb20_device *pdev,
uint8_t iface_index, char *buf, uint8_t len)
even though the kernel ioctl structure has a 16-bit length.
Hans, why not just use size_t for such arguments?
