Actually I remembered that I had seen this before in gdm_usb_send()
from drivers/staging/gdm72xx/gdm_usb.c. Apparently there is a
firmware bug.

/*
* In some cases, USB Module of WiMax is blocked when data size is
* the multiple of 512. So, increment length by one in that case.
*/
if ((len % 512) == 0)
len++;
