I've installed the appropriate kernel headers and required tools: gcc, make, but can't compile the kernel module. Getting these errors:

Should I get a newer client from you?

Change function `fthc_get_frame` on `hcd.с` on:

```
static int fthc_get_frame(struct usb_hcd *hcd) {
#if 0
struct timeval tv;
do_gettimeofday(&tv);
return tv.tv_usec / 1000;
#else
return ktime_get_ns() / 1000000;
#endif
}
```
