OK. I looked too and it doesn't look like glib offers an equivalent. 
Maybe I'll contribute this at some point.

I'd rather see it "open coded".

You're still using inappropriate constants for endpoint addressing. 
Stick to a number OR'd with USB_ENDPOINT_IN or USB_ENDPOINT_OUT. If you 
wish to give more meaningful names to endpoints, you can #define them 
like I do in other drivers.

Thanks!
