-The program is just evhz.c. Compile and run:
+Just do ./run (run is very short and readable).
- gcc -o evhz evhz.c
- sudo ./evhz

+There exists a kernel bug for USB ports which use the uhci_hcd driver,

+https://bugzilla.kernel.org/show_bug.cgi?id=60586. A workaround is to
+use USB ports that use the ehci-pci driver.
