correction:
la_write_cmd_buf is not the problem
cos it would print an error message
("Failed to send command" or "Invalid send command response")
the problem should be
hardware/sysclk-sla5032/protocol.c
```
ret = libusb_bulk_transfer(usb->devhdl, EP_REPLY, (uint8_t *)&reply,
sizeof(reply), &xfer_len, USB_REPLY_TIMEOUT_MS);
if (ret != SR_OK)
return ret;
```
which should look like
```
if (ret != 0) {
sr_dbg("Failed to receive reply for read register command: %s",
libusb_error_name(ret));
return SR_ERR;
}
```
-1 == LIBUSB_ERROR_IO == Input/output error.
can be caused by a false endpoint (EP_REPLY in this case)
this should be visible in the USB captures
